too much filter pressure?

[Staggers]

Every opening season I have something needing replacement and during that time that the part comes in (with the inevitable multiple delays) the pool gets a nice dark green. This year is no exception.

So my new pump came in, I installed it and let it run all night. This morning the pump was still running but the tank was only half full and it was not pushing water through the pump. I backwashed, rinsed, emptied the pump basket and now it's running like it should.

SO ... should I be worried about anything with my system? Would it be that the filter got too full and the pump couldn't match the pressure, so the pump just ran half full for a while? Did I damage my brand new pump?

thank you, in advance, for the help with this.

I'm sorry I can't advise you on the pump issue but....

For future reference, any time your pump is out of commission, just add your liquid chlorine in to the pool and mix it up manually with a broom or something like that. It should help keep algae at bay in the meantime.

Yippee

Very unlikely that you damaged the pump. What is the clean pressure? And the pressure when it wasn't pumping? We recommend backwashing when the pressure rises 20-25% above clean pressure.

Maybe it is time to break it down and clean the filter.

I run it 10 psi clean, backwash at 20. I'll keep an eye on it and see how it goes. May need to do a thorough check on all the joints and everything for the season

Is shaving cream still recommended on the joints to look for suction loss?

I am confused that you need shaving cream.....isn't your pump running as it should now?

 

[Staggers]

It is but when I turn it off I can hear the lines start to fill with air. Sorry, forgot to mention that part. I think I just need to check all the joints for suction loss anyway before the season starts

If the pump is off, the leak you hear can be anywhere in the system. Pump running, If you see no air bubbles in the pump lid, I suspect that leak might be on the pressure side......where the shaving cream will do no good.
