    Auto fill plumbing

    Thanks for the thought. Yeah, I know they are made in a huge amount of specifications. I didn't use the spring plunger variety, assuming that the pressure would never be enough. I think I did neck it down to 1/2" but might be 3/4". I used a stainless metal "swinging gate" valve. Some of...

    Auto fill plumbing

    I put on an auto fill on my AG pool last year. I built it into the deck, and plumbed it out. But now I realize it doesn't actually work as I had hoped. The problem is that being plumbed into the return injector line, I needed obviously to put in a check valve so that the pump wouldn't just...

    Stenner liquid chlorine pump - How to choose and install

    Yes, I'm interested also. I've only been running my Stenner pump for a year, and no problems whatsoever. I also have a completely shaded system, and less heat. I also don't use anything stronger than the 6% bleach. Can you tell us more about if the cracks are in the PVC or in the black...

    Using old rooftop solar water panels to heat pool.

    True, copper has some value. But the bladder on a panel is pretty thin. I sort of doubt that there is more than 20 lbs per panel, maybe 1/2 that. Not to say worthless, but not a huge amount. I used to use these 4 panels to keep a hot tub hot. Worked very well, kept the water at about 125 in...

    Using old rooftop solar water panels to heat pool.

    Yes, one can do that for sure. My neighbor on a ranch next to mine does that, but that is a considerably more expensive system. I think I should just go get some of the poly panels. Anyone have a good idea of which ones work best?

    Using old rooftop solar water panels to heat pool.

    Ah, so you are saying that the copper and Chlorine might indeed make for problems. I'll read that.

    Using old rooftop solar water panels to heat pool.

    Thanks for the reply. yes, the pipes too and from the panels would be PVC, but agreed, the gauge of the copper itself in the panel is fairly thin. But if destruction of the panels themselves is the only downside, then I think I might use them. They are not worth much to me otherwise. I was...

    Using old rooftop solar water panels to heat pool.

    have a 13,500 gallon AG pool I installed last year. All has gone really well, with the advice from a member here. I’d now like to raise the temperature of the pool a few degrees. Last year, in the middle of the summer, from July thru August, the pool stayed in the mid to high 70’s on average...

    Stenner liquid chlorine pump - How to choose and install

    Thanks Steve. Think I understand this pretty well. .... Well, who am I kidding. probably I understand it well enough so that I will be able to figure it out as it happens! pk

    Which pump do I choose of these two?

    Thanks for taking the time to give me a long answer. Interesting, I am on another woodworking forum and there are lots of electrical engineers on that forum and while I may well be misunderstanding, I did not know that single phase motors were able to be variable speed with such a drive...

    Which pump do I choose of these two?

    I'm not an electrician, but my understanding is, basically all 3 phase motors are variable speed, thru, as you say, varying frequency. Basically single phase AC motors are NOT variable speed. So, not saying that this is what is going on, but if it is a variable speed motor, in general, it is...

    Which pump do I choose of these two?

    Thanks Bizzle I do understand I need to wire the SWCG in such that it is not going without the pump. That can be done, but yep, will need a bit of figuring out. If I couldn't, I guess I'd have to run a different way. As to why I like DC pumps? DC motors are great motors. They used to be...

    Which pump do I choose of these two?

    Thanks VERY much Bizzle and Chuck. All very good points. Yes, I do have inverters of course, and yes, I have 220 and 110, all 60 hz. I suppose you are right about a PV sensor that might indeed save my system if it is cloudy for too long. Just being off the grid makes one VERY careful about...

    Chuck, couldn't seem to get the PDF to save here, so hopefully taking a picture of it, and I can figure out how to post a picture.
