    DE flowing back into pump

    Interesting, I hadn’t heard that. I inherited my system with the DE filter already installed. Is there a recommendation for a check valve that works well with a VSP? A quick search brought me to this one, but it says it require 5psi for water to flow. My VSP running at 1500rpm shows around 4psi...

    DE flowing back into pump

    I have noticed a new gurgling sound around the MPV after installing my new VSP. I attributed it to lower water levels running at lower speed. Is that normal? It’s possible the noise was there before but I didn’t notice because the old single speed pump was so loud.

    DE flowing back into pump

    I don't notice any hissing. I think I replaced the relief vale + o-rings last year.

    DE flowing back into pump

    You're right, it only happens when the pump is not running. I mistakenly tried that to get the water to drain more, to test the priming. But when I open the air relief valve while the pump is running, I do get milky (DE) water shooting out the valve. That seems like a new symptom - the first...

    DE flowing back into pump

    Meant to include a picture of my plumbing setup with the newish vertical SWCG:

    DE flowing back into pump

    I never noticed this my first 3 years of pool ownership, but starting near the end of last season I noticed that under certain conditions, DE would flow back into the pump, or if I had to the Polaris cleaner valve open, it would flow back into the pool. I'm not sure of all of the circumstances...

    Nidec NPTT165 Questions

    Yeah, I have a feeling I'm going to need to do some plumbing work. In that case, it may make sense to get an entirely new pump, since the idea of an easy motor swap out job is less likely. Any comparable VSP in that price range? I found references to a cheap CaliMar in this forum, but could not...

    Nidec NPTT165 Questions

    I am also looking at this motor for the same reason (at @1poolman1 suggestion). The manual mentions a built-in relay sounds like an interesting option for switching on my SWCG - does anyone know if the flow threshold is configurable? From the manual: "The Auxiliary Load Relay automatically...

    Pump makes new noise, and stops after seconds

    I tested the capacitor today and it was a little low - it is rated for 30uF +- 6%, which means 28.2 on the low end. It measured at 27.98. The capacitor is dated 2015. But my symptoms now are that as soon as I turn the power on, it trips the breaker. Would a bad capacitor cause that? I actually...

    Pump makes new noise, and stops after seconds

    Rained on for 10 years, definitely. Spray from filter relief value, yes. Totally submerged, unlikely. Ok I put the multimeter on both lines (terminals 1 & 3) and read 240V. However, this time when I turned the switch on, I heard a muted pop, and the pump didn't come on at all, and the breaker...

    Pump makes new noise, and stops after seconds

    I've seen other mentions of capacitors on pool pumps, but don't see something that is obviously a capacitor. Do you see something in that photo? Do I have to disassemble further?

    Pump makes new noise, and stops after seconds

    I turned on my pump the other day and a few sparks shot out so I turned it off. It had been raining recently and was wet in the area. That has never been an issue before, but wanted to mention it. Left it alone for a couple days and tried it again today. First I opened the strainer and verified...
