Question about Hayward 1.5 Hp Northstar High Performance Pump

1 Answer

Jet pressure I removed the winter tarp and shocked the pool, after a hour and so the pressure in the jet was not powerful. I backwashed and rinsed the filter which seemed to help for alittle while. Now I am trying to vacuum on the pool and I can seem to get enough pressure for the vacuum the work for more than about one min.

I have a Haywood pump and filter - S180t - I started it up after winter and I have no backwash or rinse pressure??


Did you drain it completely before Winter? If water was inside the pump, it could have been damaged by expanding freezing ice. The impeller could be trashed (i.e. ''physically broken'').

First I'm assuming we're talking about a sand filter. Back washing is the right thing if pressure increases.A 8-10psi pressure increase is the magic number where you must backwash. Be sure to run a rinse cycle too before returning to filter. If you want to clean filter you can buy chemicals that you add to your skimmer as you backwash. Follow their directions. If you do want to drain the water, open your basket cover on the pump and remove plug, this will allow air to enter the filter, so it will drain. It drains slowly. Not really necessary, except to winterize.l

Recommend backflush pressure of a hayward pool filter


After you have backwashed your filter until the site glass run clear. Go to rinse mode for 30 seconds. Make note of the filter pressure. Don't backwash until the pressure goes up 10 psi!! It is important not to backwash too much. As pressure climbs the sand filter actually filters better.

Pressure at 15 psi after backwashing


No that is normal pressure, when the pressure rises more than 10 psi over that in a 24 hour time, you should backwash the filter. Hope this helps

Are you using the rinse setting for a few seconds following the backwash? If not, once you finish washing, stop the pump, change the valce to rinse, then run it about 3 to 5 seconds. Shut down then switch to filter and the particles should stop coming back to the pool.
