Pressure drops inexplicably

[markayash]

What I wondered is if that bypass valve opens and bypasses the heater then heater senses low pressure and shuts down.
But thinking that wouldn't cause your flow to drop in the pool. Also seems if something was blocking it your pressure would go up.

I think James has the next next step and check vacuum at the pump. That's a weird issue

I think this pump is near the end of useful life. We found a store open today. Going to go check it out.

Price around, Pool stores pump prices are usually 40% over online

I may be willing to pay a premium for getting it today instead of in a week.

Are you saying pool stores pump up prices ?

Homedepot has some pumps, not sure how good/big but worth checking

can't remember the pricing but my cartridge filter was almost 1/2. I also priced my hayward heater and it was about the same..I am cheap, will wait a week to save $750

Wish you were i Atlanta, I would give you a 1 1/2 HP hayward superpump..Still sitting in my basement

It’s ok. We are lucky to have jobs still that pay pretty well. We ended up getting a Pentair Superflo VS. About $300 more than online but we are good supporting local business for this. And I get it today. Now to install!

You will like the VS pump, will save a lot of power and be shocked at how quiet it is.
Hope it’s fixes the issue also

Well we got it installed and got it primed. All good. Of course we were a bit impatient and got it going before the cement was really set. Gave my wife and me an impromptu shower. >.>

Redid the cement and waiting for it to bond. Hopefully it does. If not will plumb it a bit more tomorrow.

Get that electrical connection at the pump box closed up.

After letting it set for 45 minutes this time, we have no leakage and it is going well.

Heater still not going. I’ll call the guys who fixed it in the fall to see if they can troubleshoot tomorrow.

I am unsure of the best way to do this. I can press it in - the threads are either too small or too stripped to screw in. Silicone around it?

 

[markayash]

I will say LOL on the wife shower if you don't tell her
I am always over cautious and let it sit a couple hours

Did the pump not come with a new electrical conduit connector? Measure the opening and get one that fits or your new pump won't last very long if moisture gets inside.

The hole on the interior of the housing was just smooth. There’s threads where it could be screwed in on the outside of the hole on the housing. I guess I’ll have to get to Home Depot again tomorrow to see if I can find the right connector for the end of the conduit to the pump housing.

1/2" liquid tight 90 in the electrical isle.

We had a similar issue, but at our electrical box. Went to Lowe's and purchased 1/2" to 3/4" reducers (yeah, product is named backward). So, the 1/2" connection on the electrical whip now firmly and watertightly connects to the 3/4" hole in the box.
