    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

    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 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...

    How much is too much scale build up

    I'm just about to start my second season with my new SWCG. I have never cleaned it, and have read a lot of advice in this forum suggesting not to clean it too often. But I want to get a better idea of how much scale is too much before I have to do something. I'm assuming there will always be...

    SWCG Buildup

    I've read enough here to know that calcium can build up on a SWCG, but I'm surprised to see it already - I installed mine about 5 weeks ago. I keep my levels (mostly) within the Pool Math ideal ranges - TA is a little high (90), and pH seems to be constantly rising, so may be reaching 8 for a...

    Add SWCG wiring to Intermatic timer enclosure

    I'm planning out the wiring for my SWCG install. I intend to wire the SWCG control to the LOAD side of my Intermatic timer, so that the SWCG and single-speed pump are always on at the same time. I'm trying to figure out the best way to get the new wires into the enclosure. There are already 2...

    PVC rework for SWCG

    I'm thinking about installing a saltwater chlorine generator and trying to plan it out with my current setup. I'm comfortable doing some PVC cutting and cementing, but need some guidance on how to work with what is already there - I'm not familiar enough with all the various PVC connection types...

    Is it possibly my main drain is fake?

    Still getting to know the pool at the house I bought a couple years ago. I have a "drain" - at least a cover, at the bottom of my pool. When is that supposed to be used? I've never felt any kind of suction from it - with the pump on or off. Once my water goes below the skimmer, my pump fills...

    Help identifying thing on pipe

    Anyone know what that rusty metal round thing might be that is attached to the top of my pipe on the right side there (just above the black Jandy Valve)? Wonder if something used to be mounted there.

    I think I dumped a bunch of DE in my pool. Now what?

    Symptoms: my water is very murky, kinda greenish, and has a fishy smell. It feels a little slimy, though that could be in my head. I noticed my polaris cleaner wasn't being very effective - when I pulled it out, the filter bag was still holding water! I think it may have been coated with DE from...

    Does low temperature impact SLAM?

    Apparently I let my chlorine get too low too early. I thought it was too cold for anything to grow (getting down to 30s at night) so didn’t add anything for about a week. But in the past few days my pool has gotten very murky, green tint, and a bit of a fishy smell. Last year I had it crystal...

    How to read liquid chlorine label

    For comparison purposes, should I consider this 12.5% or 11.9%?

    Going through a lot of liquid chlorine

    This is my first season using the TFP approach and liquid chlorine (last year I used tabs - I have since replaced most of the water). I'm very happy with the water - its is sparkling and clear, and I no longer see the hints of algae that I used to get occasionally. However, I seem to be going...

    Is this the mustard algae I need to worry about?

    I'm a relatively new pool owner and have been lucky so far with clear water without any major outbreaks of algae. However, occasionally I'll get some yellow growth/stains in corners, or around the water outlets. In the attached picture, you should see some yellow in the corner, just below the...

    Very high combined chlorine

    The quick summary is that I currently have 0.4 Free Chlorine, and 22ppm Combined Chlorine (using Taylor K-2006 FAS-DPD test kit). I have never seen anything like that before, nor any online posts mentioning CC that high. Now I'll give the longer story of how I got to this point. I don't know how...
