    The best laid plans of mice and men

    Have been prepping the pool for the arrival of the grandkids tonight. I was just about there, only to wake up this morning to 2 drake and 1 hen Mallard in the pool. I have pigeon proofed the pool, but haven't figured out how to keep ducks out of the pool in the spring. Of course, they have all...

    Recommendations/advisibility of changing from single speed pump to variable speed pump

    Seems to be about time to replace my pump. Should I consider a variable speed as a viable option? As you can see from my signature, I think that my filter is oversized and that my pump at 2.5 HP is sized so that the in floor cleaning works correctly. The pump is run off an intermatic timer, but...

    Trying to understand TFP method and actual FC numbers

    I understand that listed numbers for minimum FC is actually 7.5% of CYA. At this minimum FC level you must have a certain amount of FC that is not bound up in CYA and available for disinfection. What is the formula for figuring the actual FC level available for disinfection and what are the...

    Think I need new cartridge filter

    My 15 year old {Hayward C5000?) filter just recently started leaking at a point between the upper and lower body parts. I got a replacement O-ring, cleaned upper and lower mating surfaces and installed new O-ring but it still leaks in the same place on the body and rotating upper does not help...

    Diverter valve rebuild and position question

    Sorry...posted on wrong forum earlier. All 3 of my diverter valves are starting to stick when moved and may be introducing air into the suction side of the pump. I will be rebuilding all 3 within about a week. I usually run the pool in the position shown with the spa supply and return off. When...

    diverter valves position and rebuild

    All 3 of my diverter valves are starting to stick when moved and may be introducing air into the suction side of the pump. I will be rebuilding all 3 within about a week. I usually run the pool in the position shown with the spa supply and return off. When using the spa I only run the spa supply...

    Broken bond wire

    When checking my yard I noticed what appears to be a broken bond wire. Not sure when it happened as it probably took a while to work its way out of the ground ( CA quake of July 2019 )? It seems to be coming from the left (towards pool as the equipment pad is to the right ). It is less than 20...

    PH reading at high FC

    Since my CYA level is about 80-90 I have found it easier to maintain my FC at 9-11 to prevent excessive loss due to Las Vegas sun and high temps. I under stand that PH readings can be difficult to read accurately as FC approaches 10 or above. My question is... are PH readings at this FC level...

    pentair air pressure switch settings

    While researching a Pentair minimax NT problem for someone I came across some useful info regarding the actual set points for Pentair air pressure switches that lists the switch set points by Pentair part number and air pressure switch label color in some cases. I don't know how to make this...

    Liquid Chlorine vs SWG CYA recommended levels

    I have noticed a large difference between recommended CYA levels for liquid chlorine vs SWG pools. Living in Las Vegas with a high UV Index, I have found it difficult to maintain chlorine levels with CYA at 40-50 due to large daily swings. I seem to have found what I consider a sweet spot with...

    Ignition modules, flame rectification and true RMS multimeters

    I have been answering questions regarding gas/propane pool heaters for a while now and thought it might be time to add a knowledge base to some of these "mysteries". AC voltage is a sinusoidal wave form that is continuously variable. It can deformed by different variables in the circuit so that...

    high FC and PH

    I have read that when FC is over 10 ( correcting for high CYA or slamming) that PH readings will be incorrect. Since the PH appears to be higher than it actually is when tested, I am assuming that the high FC is skewing the PH when chemically tested. Would a digital PH meter show the correct PH...

    Pigeon Problem solved

    When I first got my house with a pool I had 30-40 pigeons sitting on my roof in the morning waiting turns to get a drink. Needless to say I had pigeon poop all over my deck and the pool/spa spillway. Also whenever it rained the pigeon poop from the roof would wash down onto my patio. After some...

    FC available for sanitation when balancing FC vs CYA

    I have read that when balancing FC vs CYA that your FAS-DPD FC reading is not the FC that is actually available for sanitation and that bathers actually see. I assume that this is the reason that SLAM FC is pushed up so high. Is there a formula to figure out the actual FC available for...

    Chlorine discrepancy?

    Just got TF 100 kit. Daily test shows 5-10 chlorine with color nearer 10. When tested with titration FC only shows 5. Total tests: FC 5, CC 0, CA 600, CYA 80,TA 110,PH 7.6, TDS 1500. Las Vegas water starts at CA 290, so hard to keep it down with summer evaporation. I see that with CYA of 80, I...

    Pool heater repair

    I am an extremely handy retired HVAC service technician. This is my third pool in my lifetime. Recently my 400K BTU Hayward pool heater started leaking at the water header. I took it apart and order a new O-Ring/gasket. Cleaned all surfaces and installed new O-Ring/gasket. It still leaks! Do you...
