I have a Pentair Challenger 1 1/2 pool pump (CH II-N1_1 1/2A) that has a steady leak around the large square "O" ring around the outside of the pump housing.
I replaced the "O" ring after greasing it with silicone pool fitting grease but it continues to leak as before.
is it possible that the clamping ring has stretched or spread over time and is no longer the right shape? and if so should i try to squeeze it or gently hammer it into a tighter shape.
The pump is running a series of waterfalls and has a head of 30 psi. This may be to high for this pump.
Thanks
John
