DigitalMan Posted December 10, 2013 Report Share Posted December 10, 2013 So I've noticed lately when I have pump 1 on high (ie pressing Pump 1 twice) the water pressure pulsates. Is this air trapped or something worse? Quote Link to comment Share on other sites More sharing options...
Water Boy Posted December 10, 2013 Report Share Posted December 10, 2013 There could be something wrong with the pump itself, but I would check a few simple things first. Make sure your water isn't too low. Even if you think it isn't too low, maybe add a little bit of water to the spa. If the water gets too low, it can cause surging at the filter canister, which will cause the pump to cavitate and cause the pulsation you are describing as well. When the water gets topped off, it should stop that if the water was too low. Also, clean/and or replace your filter if it has been a while since you have done either of those. Check those things and report back if that doesn't. Quote Link to comment Share on other sites More sharing options...
DigitalMan Posted December 12, 2013 Author Report Share Posted December 12, 2013 Well thank you very much. Although the water appeared to be down only about 1/2 inch once I topped it up the pulsating stopped. Thanks again. Quote Link to comment Share on other sites More sharing options...

Sazl Posted January 22, 2019 Report Share Posted January 22, 2019 My tub just started this and the water levels are high, like topped right up and I haven’t changed the water in a month! So why is this happening to me is it the pump then? It pulsates and then stops for a minute and then starts again! Quote Link to comment Share on other sites More sharing options...
