Title: More fish room work
Post by: LizStreithorst on October 19, 2016, 05:19:42 PM
I went to the fish room this morning and saw a pair of RSG's in distress!  There sponge wasn't getting any air.  I freaked, but managed to fix it and do a tiny WC and get done in time to get to work on time.  They're fine.

I have a Jemhco LPH60 linear pump.  http://www.jehmco.com/html/lph60.html    I've added a couple more tanks and I'm now running 47 sponges and air stones, 7 of which are in my 250 gallon water storage containers which are deep!  I've noticed in the past few days that unless everything was perfect I'd loose air to one sponge.  This afternoon I tightened up a few valves with a wrench that I had depended on hand power to screw in when I first put them in.  It helped! 

When I set this up years ago, I drilled about half the holes with a drill that was imperceptibly too big  I bet that it was metric rather than standard or vice-versa.  And I didn't use a drill that cut threads.  I just used a drill bit.  I used lots if thread tape on the threads, but I bet that a wee bit of air is leaking from them.  Also, I didn't plumb the PVC to make a loop.  I just stuck a cap on the end because it was easier. 

I am reaching the capacity of my pump.  I must not allow a molecule of H2O to escape the system and I must make it easier on the pump by making a loop.  I've never used a drill bit cuts threads.  On 3/4" PVC.  I bet it would be best to drill a pilot hole so when I put on the bit that cuts threads it won't go off on me.  I don't have a drill press.

I suppose I should tackle this project this week end.  I have nothing else pressing...If anyone has any advice I want to hear it.  I want to do this right.  I always regret doing an imperfect job that I think should work well enough.

How old is your air line that you have running now?...it can get brittle and lose a good connection when jiggled while do sponge maintenance etc.....got more air line than you need on some connections?...you can trim 'em back some....real fine sponges getting older can get so they don't clean up well....toss em in the washer and wash em a time or two..... 8)

take a pipe cleaner and ream the valves out....wash your pump filter sponge well too..or replace it....Jehmco will do a rebuild for around $75 on most pumps, if need be too...I have one to send them a the moment too....

I bought an extra filter when I bought the pump. 

A pipe cleaner is way to big to fit through my valves.  I've been using a needle with thread to clean them when they fail.  It works great.

I replaced all my old stiff air lines with new when I set back up after the stands were rebuilt.  I cut most to a good length but there are some I could trim a good bit.

I have noticed that my ancient small pore sponges have gotten harder and harder to squeeze.  I can't toss them in the washer because they are not hydro sponges.  They're square and glued to a 4"X4" piece of tile.  I need to bite the bullet and contact Swiss Tropical's for some good sponges  It won't hurt if I buy a few at a time.

Anything wrong with the rest of my plan?  Is the drill that cut's threads what I need?  Will making a compete loop back to the pump help?

I've heard of folks making a pilot hole then putting the tap in a variable speed drill to tap in the threads....is that what you're saying?...then yup, that'll work...

sounds like you have the rest covered....and yes, I think a loop may equalize the pressure better for ya too...

The Jehmco pumps work better, and last longer if loaded....not under loaded...hopefully it hasn't weakened a bit....

I don't know if a loop would help or not. Are you going to re-drill new PVC with threaded holes? If so you need a tap that matches the threads. This video might help...

Wow!  That helps greatly  What a great video from an unassuming guy from "Dull Knife Productions".  I like that man's style.

I will buy a tap.  I don't imagine I will be able to buy just the one I want by itself.  I'll need the tool to screw it in, too.  My good neighbor might have those to loan me, but I doubt it. 

Gonna go back and watch that video again.

I asked John at Jehmco when I bought the pump if I should bleed off air to make it easier on he pump.  He asked me what tanks I had and how many sponges.  He said that I was fine, that I was buying the right pump...

I may need to think on this project a little longer.  I need to figure out the least stressful way to do it.  Least stressful on the fish, I mean.  I need to redo the air supply to the entire fish room to get it perfect.  I can do it but I have to get it all planned in my head first.

Thanks very much for educating me.

I kind of think that a loop will help.  I can't put "why" into words.  I bet BillT or Dennis could put the "why it would help"  into words.  Or maybe a loop won't help huh  I'm a bit of a dull knife myself ;)

Jehmco has self-tapping air valves for PVC. Part AV1E. If that will work all you need is a#14 drill bit.

A linear length of pipe, with several taps bleeding air off of it, will result in a pressure drop from a high point near the pump to a low point at the place furthest from the pump.
A loop will connect the far end of the linear pipe to the pump without any taps bleeding air off (in the simplest to explain of case).
This will make another pressure high point at the far end (from the pump) of the pipe. The pressure will then drop off from the high points at both ends of the pipe to a low pressure point somewhere near the middle. This should result in increasing the pressures at the far end of the pipe. Dividing the air flow from the pump in this way will probably reduce the high pressures near the pump a bit. More even distribution.

If you have large diameter pipes and small outlets, the pressure drops will be less.
Larger pipe has less resistance to air flow. Besides bleeding off air from valves, resistance along the pipe results in pressure drops along a pipe.
If all the valves are closed (a static situation with no air flow, but bad for pump), the pressure in the pipe will become equalized. Small flows out will result in smaller pressure drops.

Leaky valve ideas:
Depending on what kind of valves you have, you may be able to avoid using new pipe and making new holes (if the holes are not too loose):
1) little metal air valves: take them out, apply PCV glue to the hole, put the valves back in. Blow off the fumes before sending the air to the tanks. The PVC should fill the gap, harden up and make a new thread. Use pliers to snap metal threads free of glue.
2) little metal or plastic valves: Same idea, use silicon sealer. Easier to remove. Less noxious fumes.

I want equal pressure thought.  I'm not smart enough to know if your telling me that a loop or a dead end is better.  I think that you're telling me that a loop is better.  I asked the lady at Jehmco if I should re-plumb with 1" PVC rather than the 3/4" that I'm using.  She said no, but there has to be that the friction is greater in a 3/4" pipe than in a 1'' pipe.  I am right!

Now I just need to replace all the air pipes.  It won't be that bad but it will be worse than I thought.  I will have to do stuff that makes my back hurt.  As long as I'm going to go to all this trouble I might as well do it right and tap the threads like Dan suggested.

I can do this.  It won't happen this week end.  I'll stare at it this week end and figure it all out while I'm asleep.  I do my best hard thinking when I sleep huh

If your weakest outlet wasn't as strong as you wanted it, then a loop would help to even out the pressure among the outlets. A larger pipe will always have less friction, but at some point going with a larger pipe won't make a noticeable difference... it will just cost more.

I think if I had that many tanks I would go with 1" pipe and the self-tapping valves. You can use the plastic ones but then you have to thread every hole. And the cost difference is slight.

Speaking of threads... here is one you might remember. There is some food for thought in it.

I agree completely with this. A bit more concise than what I said.
Like Wallace said there will be a point where although a larger pipe will have reduced resistance, there will be diminishing returns on the investment and labor.
Where exactly that tipping point is will depend on how much air is flowing through the pipes. A small flow will experience less pressure loss than a larger flow.

lol.  Obviously my memory could use improvement.  It seemed like some of what I was saying was stuff I'd read somewhere...

The valves I'm using are brass with 1/8" pipe threads.  In the past I've just drilled the hole and muscled them in by screwing them.  I like the idea of tapping out the holes better.

That's what I do.  You can get a tap at Jehmco ( http://jehmco.com/html/air_accessories.html (http://jehmco.com/html/air_accessories.html) ), or better hardware/tool stores.  I think I ordered mine on E-Bay for two or three bucks.

It's really easy to tap the soft PVC pipe so you don't really need the T handle for the tap.  I just start the tap by hand and then use a small wrench to finish the job.

That's what I do. But it took me about three trips to the hardware store to get the right size tap.  If you go to the hardware store to buy a tap, take one of the valves along to get the right size tap. Don't be a klutz like me.

Some sponges some air stones.  I cleaned up the valves and screwed some of them more tightly and fixed it.  I still need to make the change to make it right.

The reason I inquired is that it suddenly hit me that the nipple where the airline fits on sometimes gets a mini clog...we cleaned (2) here today that were slowing down....it doesn't happen often...but it will slow em down quite a bit....just use a thin piece of wire..... |^|

I have a few hydro sponges but most are sponges that are glued to a piece of tile with a piece of PVC stuck in. 

I noticed that as I was doing my WC today two of my sponges quit bubbling.  It was because my huge 250 gallon water storage tanks were either low on water or empty.  Having the airstones bubbling into air was enough to make the sponges quit working.  As I filled the containers they started bubbling again.

I need to do this job.

Yep, happens often enough that I have a piece of wire hanging from the main airline for quick access.

I hate thinking.  I'm making up my materials list.  That means that I have to figure out exactingly how I'm going to plumb my air.  I realized in my sleep that I should get everything measured and drilled and tapped first.  Then I'd put in place and ready to hook up to the pump.  That way the fish will be out of air only for as long it takes to screw out of the old system and into the new system and hook up the air tubing.  After that I'll hook it all up to the pump and everything will start working as it should.  An important thing that I figured out in my sleep was how to manage the corner that I can't get to because my huge water storage containers go almost to the ceiling.

Right now I'm going over every place where I will need a each kind of connector.  I'm also trying to figure out how to get the job done with least breaking my back on the lower rack.  I'm afraid I will just have to break my back huh  This thinking part is hard.  The more I look and think the closer I get to knowing exactly how it will go, and the harder it gets on my poor feeble mind :( 

Oh well...no use pissing and moaning...I might as well get back to suffering.  The planning is always the hardest part for me.  The work itself is sometimes difficult but it's satisfying.  There is no joy in figuring out how to do it.

I would order a little extra of everything... theres always a booboo. You could lay all the parts out on the floor in front of the tanks, dry fit the parts, label them, and make a mark for the taps. A mistake I've made lots of times in plumbing is not watching the rotation when gluing... ending up with stuff pointed the wrong way.

My wife tears into things without thinking it through and I overthink things and delay the doing part. It gives us something to tease each other about. It works though... I do the measuring and cutting ("it doesn't need to be to the nearest 1/16th of an inch, Dan") and she does the hammering and screwing ("you want to try going clockwise with that, LauraLee...").

Post by: LizStreithorst on October 29, 2016, 06:11:09 PM
I always buy extras of what I figure I'll need.  That's why I have a box full of fittings.  As I was typing about connecting to the pump I realized I'd have to reduce a 1" fitting to a 3/4" slip/ MPT to hook up to up the pump!  That would have meant another delay!   No matter how much I think I almost always run into something I didn't think of.  At least the way I'm doing this project my fish won't be without air for long since the existing system will be working until I'm ready to switch over.  Rotation of fittings is not a problem for me.  I'm not great at measuring to the 16th of an inch but I don't have to measure that close for this job.

If your wife didn't have you, she'd learn to think before she dove in.  I've always had to figure it out for myself except when I was a carpenter's helper in Mobile.  It's easier doing what I was told by a smart person that figuring out how to do it myself.

I finally ran out of excuses and went to Lowes and got all my stuff.  Jack and Judy were walking down the road as I was driving home.  I stopped to chat.  They saw the 180' of 1" PVC in the back of Charlotte.  Jack knew that it was for my project.  I told him that I had put it off for as long as I could.  That I didn't want to do it but nobody was going to appear out of nowhere and do it for me.  It's always like that for me when I have a project.  I love the results but getting started is the hardest thing.

Jon mentioned using a drill to turn the tap. If you have a drill that does a good job of going slow, that would be much quicker on 47 holes.

Are you running an upper and a lower air pipe... or would it work to just have one line above? It would be harder to adjust air flow but easier on your back. I'm probably missing something.

Thanks for the suggestions, Dan.  I'll be using my 18 volt DeWalt drill.  I can make it go slow.

I would truly love to do the top rack only and run long air tubing to the bottom rack.  It would make the job almost a piece of cake and save my back.  My back can handle it, but it does bitch me out when I abuse it.  My thinking was that I had to do the top and bottom tanks separately  because it would be more work for the pump to run long lengths of air tubing  than short lengths due to friction.  I'm doing this so I can get the most out of my pump.  Is my thinking wrong?  Is it right but the difference in pump effort minimal?  I'm going to 1" PVE rather that the 3/4" I'm using now to reduce friction.

I can't wait to hear what you tell me.  I would love to make this job easier.  If I can, I will.  If I can't, I'll do the back breaking thing and bitch about it  even though I'll know that I will be very proud of myself when it's done :-[

It will increase the friction loss, but how much is hard to say. If you are already close to the maximum number of sponges with your pump, then maybe its not worth risking it by dropping the extra distance... but if you had air to spare it would be nice to have them all above. The new looped route will increase your overall performance, which is a gain... you also have the larger 1" piping working in your favor... would these gains be equal to the loss from the longer drops, and even out?? That's a tough question, and I'm afraid only trying it would give a good answer.

The air lines to the lower tanks, I'm guessing, would be a little more than half the total? And what is the distance from the upper pipe to the lower? This distance would be the additional length of each small air line. Guessing about 4 feet times +/- 25 drops?

The head loss parts of this can be calculated, but I don't know how to calculate the effect of reduced back pressure from having the loop in the system versus no-loop.

I'm not smart enough to figure it out.  I'll try it the easy way first.  If I'm not satisfied I can hook back up to the existing system and break my bad. 

Thanks, Dan.

I'm taking a break.  I tackled the corner that I couldn't get into first since it was the hardest part.  I wish I could tell one of the dogs to "stand here and hold the end of this pipe".

I'm slightly over 1/4 of the way around the room.  I'm taking at a slow pace because my existing system is working fine.  It's funny how much I despise starting a project considering the fact that once I start I have fun doing it huh

I found that kitchen twine would work as well as a dog or human who would stand there and hold the pipe.  I reminded I could crawl into a small space like a little monkey.  By back isn't breaking.  This is fun!

Bad day with the microscope.  It's no biggie.  I had a good day in the fish room.  I only work on my fish room projects on my days off because the thinking part is hard for me since I don't do this stuff every day.  All I have to do tomorrow is glue in two more pieces of PVC, remove the air valves from the old system and screw them into plumbing, and hook up to the air pump.  Everything should work perfectly.  If it doesn't all I have to do is unscrew the valves from the new PVC and screw them back into the old system which I have left in place.  Everything should work just fine.  Still, I'm a little stressed over leaving my fish without air for an hour or two.  I shouldn't be but I am

They do fine in shipping bags for days.....a couple hours is nothing......

I see, you only have one set of valves. I hope it works.

It'll work just fine, Dan.  I've learned to take time figuring out the best way to do fish room stuff.  This is air!  It's of greatest importance.  I took a long time for me to figure out the best way to do it so in case I screwed up I could get it working again.  I have taken a very long time putting it up.  I check myself a gizillion times at every step by taking a break and putting it on a back burner.  I want it to be clean like something a pro would do.  Mostly I want it to work perfectly the first time with no unfortunate surprises.   My carpenter could have done it with a helper in half a day, but I know how to do "simple" things like this myself (with a little help from my friends).

Mug, I know damn well that a few hours is nothing.  But what if everything were to turn to shit and the new stuff didn't work and I couldn't get the old system working?  I know that it won't happen.  I have so much stupid insecurity sometimes.  Other times I think I'm wonder woman huh

I don't know if I pussied out or got lazy.  I put in some water valves that I'd been needing instead of finishing the air.  Later I shipped off a couple of fish.  Mostly, I just piddled around wfwf

I am ashamed.  I didn't want to do it on a work day because I was afraid I have not taken something into consideration and have to run to town while the fish had no air.  I thought I'd do it yesterday but I looked at the state of the house and decided I couldn't stand it any more.  I spent the day cleaning instead.

I'm finally at it now.  I have all the tanks on the top rack connected to the new system and I have bubbles galore.  I thought I'd smoke a ceegar and drink a beer before I cut air line and hook up the tanks on the bottom rack.

All done.  I can tell that I have more air now.  I don't know that I'll have enough to put 9 sponges in my 3 150 gallon outside containers.  I'll find out when I set them up next summer.
