    Pentair Posi-Clear RP Cartridge filter lid leaking

    You are absolutely right! I don't know how I missed it! I inspected the o-ring and did not notice anything wrong with it. Just in case, I ordered a new one and hopefully it will fix it. Thanks a lot for pointing it out.

    Pentair Posi-Clear RP Cartridge filter lid leaking

    Last weekend, I cleaned the cartridge as I regularly do, put the lid and the lock ring back and everything seemed ok. This model has no gasket or clamps and the lock ring clicks in place without any problems. The next day, I noticed there was leakage through the lid, what never happened before...

    Kreepy Krauly Great White problem driving me nuts!

    Surprisingly enough, the problem was the oscillator spring on both units. It seems that over time the springs get too compressed and lose the ability to keep the gears together, creating a small slack between them. Because of the slack, the gears may angle just enough to kind of get locked to...

    Kreepy Krauly Great White problem driving me nuts!

    I have an old Great White that was working fine until it decided to keep rotating. I noticed that the brush would come out and not retract, causing it to go into an endless pivoting. After replacing gears and disassembling and reassembling everything several times, I gave up. I bought a used...

    Zero chlorine all of a sudden

    Sorry. I do have a SWCG. According to PoolMath using the TroubleFreePool suggested levels, the ideal FC for my pool is 4.

    Zero chlorine all of a sudden

    Unfortunately, I am back. As you can see above, back in July I was having problems with chlorine disappearing from the pool, and with the help of the people on this thread I performed the SLAM process and have been good since then. I had been checking the chemistry regularly and everything...

    Zero chlorine all of a sudden

    Last night: FC still 21ppm and CC zero. This morning, FC 17ppm and CC zero. No loss during the day, with sun and rain but 4ppm loss overnight???

    Zero chlorine all of a sudden

    Tested before going to bed last night: 21ppm and zero CC. This morning: 21ppm and zero CC. No loss! I will test for one more night, but it seems that the process is complete.

    Zero chlorine all of a sudden

    I am back in business. Received the reagent today. FC at 22ppm and CC at 0.5ppm. Water continues extremely clear and there is no visible algae. I will let the FC progressively drop to 16 as suggested above. I was using a higher number as the chlorine/CYA chart for SWG starts at CYA 60ppm and I...

    Zero chlorine all of a sudden

    I am back. It seems that the situation was not resolved. So, I started again, now using the Taylor K-2006 kit for accuracy. Here is what I did: - July 26 - Early morning: Close to zero FC on the pool. Reduced the pH to 7.2. Measured TA and got 60. Measured the CYA and got 35ppm. Checked the...

    Zero chlorine all of a sudden

    So far, so good. Chlorine levels seem to be holding. For my surprise, the cartridge filter was very dirty, even though I had replaced it less than a month ago and the pump pressure had not increased. I wonder if the algae were sticking to it. I guess cleaning it also helped. I will clean it...

    Zero chlorine all of a sudden

    Thank you for the fast reply. A couple of questions: how do I calculate the amount of liquid chlorine to add (trial and error?). What is your best guess of why this problem happened, so that I could prevent from recurring?

    Zero chlorine all of a sudden

    I have been successfully taking care of my pool for almost 5 years, with no major issues. Last weekend I noticed just a few little dark dots on the floor of the pool and thought:: algae! I brushed the pool and they disappeared. I tested the water and to my surprise, zero chlorine. My first...

    URGENT! Motor is screaming and I am about to!

    Which seal or seals? I see a water leak on my current one and it is likely that was the cause of the damage to the bearings, so I assume a seal or some seals are bad. Thank you

    URGENT! Motor is screaming and I am about to!

    I guess I will stick to the 1 HP then. Would I need to buy any seals if replacing like for like? Thank you all for your comments and suggestions. This is an amazing forum. By the way, best price I found so far was at Amazon (and free shipping for Prime). Would never imagine...

    URGENT! Motor is screaming and I am about to!

    Thank you for your fast reply. Sorry, just one more question: would I be better off replacing the 1 HP motor with a 1.5 HP motor? The installer of the solar panels said my 1 HP was fine, but the guy at the pool store (which may just be willing to sell) told me that with the panels I would be...

    URGENT! Motor is screaming and I am about to!

    Can I replace a one speed motor for a 2 speed without having to replace anything else? Thanks

    URGENT! Motor is screaming and I am about to!

    In the last few days, the motor of my pump started to scream something like "oooooo" that is getting louder and louder. Based on the fact that it is also leaking a little bit of water and there is salt around the bolts, I would assume that a seal went bad and caused water to get into the bearing...

    SW recommendations not matching store recommendations

    Thank you all for the fast and great replies. I will take your suggestions, as I have been fighting all the time to low the pH and it keeps creeping up. It seems that the numbers suggested by the stores are not helping. Another interesting thing is that yesterday I took a water sample to a store...

    SW recommendations not matching store recommendations

    I am new to this and just read here the recommendations for salt water chemistry: FC 4-6 ppm PH 7.5-7.8 TA 60-80 CH 250-350 for plaster CYA 70-80 Salt 200-400 ppm ABOVE recommended optimum level Borates 30-50 ppm (optional) I just had my water tested at Leslie's and they recommend: FC 1-4 ppm...
