We had our pool put in shortly after we moved into our house about 6-7 years ago. I have always found the pump very noisy, but one way if dealing with this was to shut it down during the day while we were using the pool. This also made sense because our electriciy utilioty (Toronto Hydro) went to TIme of Day electricity pricing so it made more sense to run at night rather than during the day.
I am now looking at putting in roof mounted solar panels for heating the pool water. That means that I should be running the pump during the day.
So what pump can I get that is as quiet as possible? Note that I did have an enclosure made in the past to quiet down the pump but that only helped a bit. If I can get a pump that is significantly quieter than I am willing to pay 2X the price.
FYI - my pool is 18'x36' and has a max depth of 8' and a shallow end of 3'. I believe it holds a little over 100,000L.
p.s. There is a web site called silentpcreview.com that exists solely to test computer components for the amount of noise the make - we need this for pool pumps as well.
