I'm not even sure if product is escaping the reactors anymore when they are powered off. I haven't cleaned out the sump yet, so for all I know the foams are doing their job and the initial escaping was just a misfire on my part when loading them
I need check valves as my reactors and pumps are in the return chamber, but the outlets are in the chamber before the socks and that chamber has a higher water level. Hence, when they are powered off, water back-flows through the reactors
I could run the outlets into the same chamber as the pumps, but I'd rather have it going back through the socks
And although it's a good suggestion, I don't want any more hoses in there, but thanks any way Tim
Thanks neoh, but I'm looking for barbed valves and I believe Corix only has PVC pipe style ones
Plus I can't get there anymore due to working hours
