PB4SQ LEAKING

[wireform]

As I'm not too familiar with this pump but came upon it this morning to find it spraying from the sides (both sides) as pictured at the label edges. Was wondering if there's a failing seal in there or sign it's gone. The cleaner is/was in the water at the time with no kinks or obstruction which one would think can contribute to this.

It appears to be a cracked housing. You may need to replace the whole thing.

It is a well known design failure.

File a warranty claim for a new housing.

Polaris PB4SQ Booster Pump leaking from body

Has anyone seen leaking from a 1 yr old Polaris PB4SQ main body? It is literally coming out of the main body, not a seam or joint. I am not sure if there is a rebuild kit or washers. Any recommendations or is 1 year the average life of Polaris Booster products? Any suggestions on a better...

found a leak on my pb4sq booster pump

Found a leak on my pb4sq booster pump do you think the pool pump body replacement (R0723100) is good enough or should I also do the o-pring replacement repair seal kit as well?

Thanks to all who responded. While I was waiting for hits on my dilemma I googled and found similar experiences. May just order the upgraded version and get it done.

Update:
I bought the new housing from Amazon (new design) which comes with a set of two gaskets. The bottom two bolts were tuff to say the least and a bit of a bear because I didn't want to remove the electrical so with a knee pad on the floor with limited space and being tethered by the seal tight connection got it done. The large black O ring/seal was looking like it's twenty years old, literally brittle and the orange O ring had a split and couldn't reuse even if I wanted to. The problem I ran into was the replacement orange O ring was way too small and I just stretched it with my two palms and kept checking till it was a good fit but what are they thinking when it was included for the repair. Reassembled it with anti seize on the bolts as I do with most repair work so future repairs are a non struggle. I have seen the aggressiveness of impact tool destroying the weaker of the two metals which in this case would've been the housing losing the thread possibly so it wasn't even a thought in my mind.
