smallreef July 8, 2012 July 8, 2012 SO, this is my overflow setup... obviously I have a plumbing problem... The setup you see coming from the left goes about 1/2 an inch down to the right,, has a flushing effect... VERY LOUD and very annoying can someone else give me an idea on how to fix it... as far as I can tell Im just going to have to cut the PVC off and put 2 seperate soft lines to the sump
Fishie July 8, 2012 July 8, 2012 (edited) Is the durso making a gurgling sound...if yes...I've had success making a small hole and either leaving it as is or sticking a small piece of tuning in it ....it's made mine silent....dead silent Edited July 8, 2012 by Fishie
smallreef July 8, 2012 Author July 8, 2012 I dont have a durso or any other piping than what you see... its just 2 overflow holes drilled through the back of the tank....

I have never really understood the science of this. How far is the tubing sticking down into the pipe? A little? A lot? Thx in advance.
GraffitiSpotCorals July 9, 2012 July 9, 2012 You need some vents close to the bulkhead. What does the inside of the tank look like?

Origami July 9, 2012 July 9, 2012 You normally vary the depth of the tubing in the drain until it quiets down. The problem that I see is that you have such a long run on the left and the two sides are tied together into a common drain. What's happening is that the left hand drain is acting like a plumbing vent and is sucking air through the bulkhead. A piece of tubing may help, but I've never seen a drain come off horizontally like this. I like to tee off of the back of drains like this. Alternatively, you can use an downward pointing elbow with a piece of tubing tightly inserted into a hole drilled into the top of the ell.
GraffitiSpotCorals July 9, 2012 July 9, 2012 Also on drainlines I always go straight down then when I combine them I make sure the pipe size increases so the water doesn't fight to get to the sump.
treesprite July 9, 2012 July 9, 2012 If you have 2 separate drains, you can add valves to more finely tune the outflow to match the return pump flow, then you get less noise.
zygote2k July 9, 2012 July 9, 2012 turn down the flow on the return pump until the gurgling disappears.
smallreef July 9, 2012 Author July 9, 2012 The pump barely seems to have much pressure as it is, if I turn it down in its current position there will be no flow, lol Its not a constant gurgeling,,, its more like a flushing, which is leading me to believe that the one overflow is fighting for air while the other is fine... What I have decided to do is cut off what I have in the back, put on an elbow on each with a ball valve near the top and have them head down at a 45degree towards the center, and then put soft tubing on each to go into the sump/// hopefully this will stop it, then if I need to I can shut the valve to make them match....
Integral9 July 9, 2012 July 9, 2012 obviously I have a plumbing problem... Indeeed. I think the slopping down and the asymetry are your problems. You could replumb the whole thing, but might end up with different problems. For a quick fix, you might consider adding a T to the horizontal line pointing upwards. Then attach a small piece of plumbing so it rises up above the tank rim. Then take a PVC cap and drill a hole into it (about 1/8" should be fine). Then put the cap on the stand pipe. I wouldn't cement the cap on until you get the hole the right size.
GraffitiSpotCorals July 9, 2012 July 9, 2012 Don't cement the cap since it doesnt get water to it and then it also acts as a cleanout in case something gets stuck in the pipe. Redoing the plumbing without vents (the t's) you will probly have the same issue.
smallreef July 9, 2012 Author July 9, 2012 SO it seems it would be best to cut off what I have on there, put on T's from each overflow pipe out one with a cap (with a hole) set ontop and the bottom with a pvc piece and then some flex hose to go into my sump? or should I just hard plumb it all the way down?
GraffitiSpotCorals July 10, 2012 July 10, 2012 Sounds like it would work to me. I only hard pipe mine because I have a car that loves to get into stuff and I would be scared he would play with the flex. Either should work.
GraffitiSpotCorals July 10, 2012 July 10, 2012 Cat that is, my car is parked outside and rarely comes near the plumbing on our tank.

Yes. It would be better than what you have there now.
flooddc July 10, 2012 July 10, 2012 If you have 2 separate drains, you can add valves to more finely tune the outflow to match the return pump flow, then you get less noise. 1+ I'll get used to mine after a while. It's actually work out great for me because, if I don't hear it. I know something is wrong.
Origami July 10, 2012 July 10, 2012 You know, I never "tune" my drain by intentionally restricting it without having a secondary (backup) drain to handle problems if there are restrictions in the first. I think that's setting yourself up for a problem. A Herbie-style drain has a backup for this very reason.
GraffitiSpotCorals July 10, 2012 July 10, 2012 Yea lots of people suggested valves on a drain to me but I think the odds of something getting stuck in the drain where the valve is is to high. Our system is fairly loud and I would rather deal with noise then worry about what could happen.
Origami July 10, 2012 July 10, 2012 I don't mind putting a valve on a drain. I just leave it wide open unless I need to work on the plumbing and have need to do a little surgery.
treesprite July 11, 2012 July 11, 2012 1+ I'll get used to mine after a while. It's actually work out great for me because, if I don't hear it. I know something is wrong. I feel the same way. I like some sound, just not so loud that it would keep me awake. As long as I can ever help it, I won't keep a tank with only one drain hole.
smallreef July 11, 2012 Author July 11, 2012 Well, considering ourr bedroom is on the 3rdoverflows floor and the tank is on the first and its loud enough for me to hear ...ugh
