Pool filler pulsating water noise when the pump is running.

[Sn00py]

Recently I've noticed that my pool filler will pulsate when the pool pump is running. If I turn off the pump pulsating noise will stop.

Where is the water level in relation to the skimmer mouth (e.g. half way)?

Do you have a waterfall or spa that is engaged when this occurs?

Is this a new autofill?

The water level may be dropping slightly when the pump turns on forcing the fill to run.

As for the oscillation, that could be because the autofill is new and the valve stopper is quite elastic allowing the float to bounce.

If the water level is above 1/2 the skimmer mouth, then you could try adjusting the autofill float to one stop down (i.e. slightly lower level).

- the water level is about the halfway, not higher..but will check later today
- no waterfall or spa engaged
- was already installed when we moved in (3y ago, might be installed around 2017)

Is there a 'better' valve stopper on the market that I can use?

That is the same one I use and it seems to work ok for me. You might check the seal on the end of the float to see if it is worn at all. But you might want to turn off the water first.

Do you have an attached spa? Is it raised above pool level?

Nope

@mas985 water level is a bit more than half in relation to the skimmer so I adjusted autofill float for one stop down
