Replaced a similar size unit that was a cheap Asian version that made a loud, annoying chatter when in use. Did my best to research other reviews/videos about its noise level and I was not disappointed. When in use, it just has a soft hum that doesn't wake up the neighbors!

I have a 1989 Formula PC29....and the pump I had in it went bad.....When I pulled it out....the date stamp on the "Shurflo" pump was.....1989!!!!! It was the original pump! So this "SeaFlo" has ONE tough act to follow!I can tell you that the poor old Shurflo had been failing for a while and I am guessing that is why it was so LOUD! It worked...so I didn't mess with it....I just thought it was a loud pump!Now after installing the Seaflo....WHISPER QUIET! A HUGE "Night and Day" difference!I read a ton of reviews about threads not matching the stock configuration....I had NO PROBLEMS! "Bolted" right up to my existing PEX lines!I did have to get a little creative as my original pump did NOT have a strainer on it....so I had to mount the new pump in a different area, but that's not the pumps fault.....So far (it's been LESS than a week!!!) I have been impressed! The pump works fine!One thing you may want to be aware of....is this pump DOES have the "5 Min on...10 Min off" cycle, so if you shower with it....plan accordingly! I don't think that was covered in the info on the ad.....We will see if it lasts! I see some reviews stating "Mine died after a year".....but we all know it could be a million factors that caused the issues.....
