    Can't figure out why pool is cloudy

    He does not have a test kit nor interested in using one - he relies on the pool store. I just thought I'd test once with my kit to see if anything major was off.

    Can't figure out why pool is cloudy

    I have had no issues with my pool in so long, I've forgotten a lot of things I've learned here. But a neighbor has been pouring lots of money into his pool with no luck clearing up the cloudy water. It is a 7 foot deep pool, and is not terrible, but definitely can't clearly see the drains at...

    Solar panels not draining when pump is running

    I was thinking of adding a second valve on the return so that when solar is shut off, the panels are removed from seeing any pump pressure and then dumping the solar water back into the pool - but it would require the addition of another return line, or I could use the vac line except for that...

    Solar panels not draining when pump is running

    I have the temperature set for 86 and what typically happens is the pool cools overnight, the pump comes on about 11 am and the controller diverts the water to the panels. Sometime later in the afternoon the temperature reaches the set point and the valve is turned so no water can go up to the...

    Seeing white flakes (calcium?) in pool after 10 years of never having them.

    All chemical levels have been the same. The SWG cell was replaced 2 years ago. I only started seeing these white flakes after adjusting the TA. My numbers were: Salt = 3600 Chlorine = 5 PH = 7.8 CH = 330 TA = 20 So I added enough baking soda to get TA to 60. Then added about 1/4 gallon of...

    Hitec Helicoil panel leak

    Friends just bought a home that has 10 year old Hitec Helicoil panels installed. The panels are 4 foot x 10 foot and there are about 10 on the roof. All 5 bottom panels have leaks at the lower part where the tubes connect to the header. This is where the pressure is highest and their system...

    Reducing overall pressure

    Filter pressure, solar bypass ~ 10 psi Filter pressure, solar 100% ~ 18 psi I have the solar valve set so filter pressure reads 14 psi, so some portion is bypassed. From what the manufacturer has told me, pressure is very important. I also think the cycling of panels, on and off, causing them...

    Reducing overall pressure

    OK. Panels are Solar Bear, about 15 ft average above the pump on the roof. Very close to the pump, so minimal pipe run. Yes, I have recently installed a solar valve with the check valve built in, so the panels drain properly. If you don't think pressure is important in the life of the panel...

    Reducing overall pressure

    I have measured 4-5 psi up at the panels at the lower header. Talking to a rep at the company, I was told the lower the pressure, the longer life I can expect. But back to the question.... will a return loop lower pressure enough to make it worth plumbing?

    Reducing overall pressure

    The lower the pressure, the longer my solar panels will live.

    Reducing overall pressure

    Other than changing to a variable or 2 speed pump, what are some ways to lower the pressure on my system? I had two ideas. 1. Use larger openings for the returns. 2. A return loop from the output to the input of the pump with a valve - although I'm not sure how much that would actually...

    High pressure in solar panels

    Thanks mas985. You would not believe it, but I was an IT guy once - but that was back when Fortran ruled.

    High pressure in solar panels

    This is the best I can do. I used to have no problem inserting images, but now it says they are all too large even if they are 200k. https://lh3.googleusercontent.com/-eaoho6RYS0M/VwwN3XadvRI/AAAAAAABaE0/wSf-pmJhP9M2QyjFf_rbqBeLZBpNeaUCwCCo/s800-Ic42/valve.jpg

    High pressure in solar panels

    If you look back at my photo, you will see a small valve T-d into the solar panel input line. Not shown is a similar setup above the return checkvalve. If I use the washing machine hose to connect the two, would that work? Thanks
