Replacing a motor on a pump, and getting the correct size for your pool?

[mitchryan912]

Fired it up for about a half hour late tonight. Found I had a multiport valve leak and still haven't finished rebuilding the filter yet, so I'm leaving it off until tomorrow when I'll have time to monitor it to make sure everything is working.

Been running for a while, and it's fairly hot to the touch, and I'm only seeing 12 psi at the filter. However, the skimmer is sucking things in at a rate like I've never seen before, so I guess the suction seems to be working well there. Should I be worried about the pump being too hot, or is that pretty normal?

Pump motors can get pretty hot but unless it is shutting off, it is probably ok. One reason to run on low most of time.

After being down for a week, I wanted to get it going. I have an Intermatic T10604R timer to control it, but it's not hooked up yet. Probably should have the electrical ready for it by tomorrow (there was NO timer control whatsoever prior to this whole ordeal.)

I'll probably have it on low most of the time, shutting it down for about 6-10 hours a day at first, until I figure out how much I actually need to run it to keep it clean. Our yard has arbor vitae trees as a privacy fence around our whole yard, so the debris from them lands in the pool all the time. Probably can't shut the pump off completely for very long.

...and the SQS1072 is smoking. Could this still be too large of a pump, or not large enough? The pump is having problems priming, and is overheating right about where it's getting close to being fully primed. Im at a loss as to what's going on...

The motor is the same size as the old motor so should be fine.

But make sure everything was installed properly (impeller ring, diffuser, seal, etc). Any misalignment can cause overloading in the motor. Otherwise, you might just have a bad motor. I can happen sometimes.

I installed a vacuum gauge on the basket side today, and on its own, it wasn't able to get much more than 1 mm Hg. Later in the day, I stuck a drain king into the skimmer and had it blasting water towards the pump, and only then did it shoot up to 20+ mm Hg. The motor still kept shutting itself off before it was able to get full prime though.

It ran just fine for a week before I changed some of the plumbing around. It would be easy to say THAT is the problem, but since we've owned the house, THREE motors in three different plumbing configurations have had problems that caused a motor to stop working. The pump that came with the house worked in the fall we bought the house, but then didn't start up the spring after. The replacement pump worked for a year, but then that motor failed. Now the new replacement motor that we bought on July 20th has died.

I've emailed the company I bought it from in hopes there is at least a 30 day warranty on it.
