FYI - Strainer O-Ring source

[sybrmike]

I couldn't find a 3-1/8" O.D. o-ring for my raw water strainer at big box or auto parts stores. Then realized it looked to be the same size as my pool chlorinator.

$1.59 at Pool Warehouse sure beats $4-6 at a marine specific source. A true plumbing supply house maybe even cheaper.

Great find, you will get very little suction if you don't have an o ring
