18' x 9' x 3.5' catfish tank build in progress.....

  • We are currently upgrading MFK. thanks! -neo
thanks for the update. the gates should work fine but I do agree that you need to have a way to change them as I too have had bad luck with them after a bit of use they leak and weap. the pics are great. keep up the good work.
 
Lookin' good I can't wait to see some fiberglass in there.
 
Nice pics! Haha! Those gate valves are what they use on RV waste tanks! The only way they don't stick and last is to silicone grease the rubber seals. I don't think silicone grease is fish safe though. Debris also gets stuck in the seals and causes them to eventually not shut all the way. I would use ball valves like stated before. "Cheap" usually bites one in the butt!

It will help but silicone spray washes off after a while. There might be a fish safe silicone grease. I think they use something like that in food handling equipment.
