Our 3 hp variable pump has finally died on us. We knew the time was coming since it was making unusual noises and pool service guys working on something else unrelated to pump told us they think our pump will die eventually, but is fine for now and functional. However, days are numbered.
Historically, we have had issues with air bubbles coming out of the jets (both pool and raised spa). It is possible the issue is coming from our Hayward 1750 cartridge filter which currently won’t secure close all the way (due to threading issue). We’ve never been able to figure out how to stop the air bubbles from coming out.
The pool service company we hired in the past to diagnose something unrelated told us we probably want to downsize the pump from 3hp variable to 1.85hp variable to help (or solve) the air bubble issue - is that a valid suggestion? Maybe it makes sense… too much HP is trying to pull (pump) water from pool, that the pool equipment system cannot keep up, so it ends up sucking air in. We do see the skimmer barely show any water in it from time to time when pump is pulling water hard, but then pump lets up for a bit, the water level in skimmer returns to normal. Is this indicative that 3 hp might be too much for our pool?
Want to check in with the resident experts on this forum before we make a purchasing decision (new pump replacement).
Description of the pool can be found in my post signature, it still holds true today. By the way, we did used to have 1.5hp pump (not variable) when we originally bought this house, before we replaced that with 3 hp variable pump a long time ago when the 1.5 died on us. Back when we had 1.5 hp, we never had air bubble coming out of jet issue. When we first started to use 3hp, we didn't have air bubble issue either, but few years later we started to have it.
