Sqwd???

[Jason McK]

I ued one in a closed loop after about 3 months it jamed and I was unable to access it so it never changed direction. I have since taken down the tank and cleaned the SQWD it worked after that but never installed it

I've run one for 3 years now. I'm on my 2nd one. The first one lasted over 2 years. They are absolutely silent...require no power...but are very sensitive to sand. Ensure that you have a sponge filter in front of the return pump.
