My Hayward pool pump is pulsating rather than keeping a constant flow of outward water. It expels water continuously, but about every 10 seconds or so it will pulsate a much larger flow of water for a few seconds and then keeps this repeated cycle of steady to pulsated water flow. Any thoughts or possible solutions would be greatly appreciated.
Make sure all intake unions are tight you have a air leak or top pump seal is bad
SOURCE: The pump (Hayward) is rattling loudly, a pulsating vibration
Like a bearking grinding noise? or inside the wet end noise? if in wet end then it could be something broken inside or you have a rock inside by the impeller or diffuser open it up and check for anything broken up
SOURCE: it pulsates; but pretty much stays in one spot
check your diaphram for a tear near the plastic ring that hold it on the tube
SOURCE: Barracuda Zodiac G3 is not pulsating. It's got
either some debris is caught in the diaphragm or it's deformed enough to render it inoperable. Unthread the nut just above the handle and pull it apart, then push the white tube downward until it comes out of the bottom of the unit. Inspect the diaphragm to see it there is any debris in it or if it is deformed. Usually the diaphragm has a uniform opening, if the gap is wide, it will not function. The most common problem is that the diaphragm needs replaced. Hope this helps.
Thank
you for posting your question here on Fixya.com.
The
Hayward H100 has a diverter plate welded into the header that helps direct some
of the water flowing thru into the heat exchanger to heat the water. If the
weld fails the diverter can interfere with that flow and cause overheating or
poor flow thru the heater which in turn can lead to the problems you describe.
Remove
the inlet side hose once you have blocked the flow of water from the pool and
you should see the diverter in the inlet. If you can move it then it is broken
and needs to be fixed back in place or the whole heat exchanger needs to be
replaced.
If
the diverter is not moving then your issue is likely an overall water flow one
and the next place to look is the filter. Poor overall system flow may be
enough to close the pressure switch telling the heater the pump is on but not
enough to keep the water in the exchanger from getting too hot, again causing
the symptoms you describe.
