Pump Woes

[NullQwerty]

It's a 36 X 18 foot inground vinyl. Deep end is 8 feet and shallow is 2 or 3. So, my guess is about 24,000 gallons. The pump is the Hayward EC-65 which is 67 gpm.

Edit: 67 gpm was specs from the internet. The filter itself says Flow range is 35-65 gpm

If your filter is rated for AT LEAST that many gpm's, the pump size is fine.

Got your message after I wrote that last one. Ok, so the previous pump that was used was too small then?

The filter actually says the flow range is 35 to 65 GPM

Let's get back on the same page.

Your pump gpm should be LESS than your filter gpm. IMHO, your new pump is too big.

Thanks for the help! Went and exchanged it for a 1 HP Super Pump. They didn't sell any dual speeds or I would have checked those out.

Thanks again everyone!

Just to finalize this thread, I installed the new pump tonight and while I was doing that installed a Union and Ball Valve to make removing the pump at the end of the season easier.

The new 1 HP pump is great and extremely quiet. Apparently my old pump was extremely loud, but I just didn't know it. Having never heard how loud or quiet it was supposed to be, I was clueless. I now know though that the old one was squeeling like crazy. It was probably my sign that the pump was about to die.

All is great now though. The PoolForum and you guys pulled through for me one more time. Thanks!

D'oh!!! My pool documentation from when I purchased the home was wrong. The previous owner had written down that I had 1.5 HP pump, and I guess I never doublechecked. I just noticed that my previous pump is a 3/4.

So, I called up 2 pool stores but both said that I want either a 1 or a 1.5.

What do you guys think? Did I buy the wrong size pump (1.5 hp), or will I be fine with it?

Also just to mention, the pool has 2 return jets (using a multi-valve port set to 1/2) and 1 skimmer. The return and suction lines are 1.5" thick.
