Mrc8858 said:Bout time lol which one did you get? And we are having a major communication issue lmao. Ok.. the return pump runs to the pvc, the pvc then runs up to the top of the sump and a short piece towards the back, then you have the first visible elbow in that picture. From that elbow why did you run it down and then over instead of just over to the T.
CorallineAlgae said:You have to add a check valve on the return lines. This is pretty critical because it'll stop a back siphon when the power is out. If you don't have one the water will drain into the sump all the way down to where your lowest return is in the tank. That would be most of the top tank.

CorallineAlgae said:I mentioned the check valves in my posts on 11/10 and 11/11. BRS has a couple of different ones in the 3/4" size. I'd get any one for the high return and a really good one got the lower back wall return. That's the critical line that needs to be protected from back flow. I use the iPod app so it's hard to post links.
CorallineAlgae said:Then it's a simple choice. Just get two of the $18 ones. You may even be able to get by with one. Call BRS and ask them what they think. It may be better to get one good one placed a bit lower in the return line than to have 2 normal ones placed at each return. Either way, they deal with these questions all the time and they know their stuff. See what they say and let us know what you decide. I'm sure whatever you do will work out.
Mrc8858 said:If its just a slow leak then it shouldnt be an issue unless you can see bubbles traveling thru the gaps.
They both have points. The thing is, your system needs it. Nobody drills three extra holes low in their tank for returns without using check valves. If the power goes out or you turn off your pump gravity WILL push the water down whatever pipe is connected to any one of those holes... unless something stops it.
I'd put one check valve right under the "T" that splits your two return lines and one above the "T" that goes to the low return. That way, if the first check ever fails the second one will be it's backup.
I've plumed many many many tanks. Almost none used checks. The ones that did use them truly needed them to protect the home or business. In your tank it's only optional to have the second check under the T for backup. They can fail. I'd use both.
okay you have a point lol im confused as to where u want me to put these valves tho? the one above the "T" i get, but one below? the "T" runs horizontally
