Hi all - I cleaned out the strainer of my Northstar pump yesterday, lubed the O-ring and replaced the cover. Now, water leaks out of the cover when the pump is turned off. I guess the seal on the cover isn't enough to hold the back pressure when the impeller stops.
The pump was perfectly fine before I took the cover off. The pump is one year old. Is it possible that the O-ring needs to be replaced already? I also noticed that Hayward doesn't sell the O-ring separately, and instead, you need to buy the whole cover assembly?
