Al,
Thanks for replying! Immediately before replacing all the seals, gaskets and impellor the pump was very quiet, just as it had been for as long as i have owned it, but leaked a lot of water. The pump is a spx1610, i think that it is pretty old, perhaps even the original pump with the pool (early 1980's). I replaced all of the seals, gaskets, and my impellor, put everything back together, leaks stopped, but noise started. I took everything apart this morning to see if i missed something, or perhaps the ceramic seals were not lined up, but nothing. the noise seems to be originating near the rear of the pump and resonating from there. I am getting better pump pressure than ever, but it is so loud that it makes it difficult to enjoy swimming over the noise. The noise does not seem to subside as the pump heats up, if it does, it is not noticably. Thanks again for everything!
