    Finding different o-ring part numbers for pentair fns filter standpipe

    Yes! I went to the pool store, told him what filter I had, and the guy knew exactly what I needed. But both part numbers I thought it might be, that said on the website in stock, weren't showing in the stores computer system, but he said 'you're just looking for the manifold O-ring right?'...

    Finding different o-ring part numbers for pentair fns filter standpipe

    Its still on the pipe, but I'd be worried it may be deformed/stretched to try and gauge by it's size to a new one. Even though I may start convulsing as I hand over the money, I may just drive down to the pool store. Both of the part numbers I think it could be show to be instock on their...

    Finding different o-ring part numbers for pentair fns filter standpipe

    I'm wondering if anyone here might know if the mfg year of pentair fns plus de filter is a factor in getting the correct standpipe to manifold o-ring. Something I thought would take 15min to order is now going on 2 hours. -The expanded parts diagram in the downloadable fns owners manual on the...

    wow, hayward no warranty vs circupool 7yrs (prorated-and haven't dug into the details on that yet) And now understanding what the 10,000 hr life standard means, I just went back on that discountsalt site and see that the RJ-30 ,RJ-45, & RJ-60plus all are rated at 15,000 hrs. I also just saw that...

    Help/opinions with SWG selection

    Did some searching learning about REEs - I had no idea of all the products that use them creating more demand driving costs I take back thinking it was SWG mfgs greed. Seems like the mining companies may actually hold all the cards good to know the RJ-45 should work at least as low as around...

    Possible reason why cheap pool thermometers give wrong temps? (tube glued into holder at wrong reference temp)

    Same here, just really posted/asked out of curiosity. Many of the documents I searched on the US nist.gov standards and measures site regarding themometers mention the reference mark, but none seem provide a standard reference temp, other than saying its 'often the freeze point', which def not...

    Possible reason why cheap pool thermometers give wrong temps? (tube glued into holder at wrong reference temp)

    I just purchased 2 inexpensive alcohol filled LIG(liquid-in-glass) thermometers for the pool. Sitting side by side 1 is consistently reading 3deg higher than the other and then I noticed both have a black horizontal line marked on the glass, one lining up about 70Fdeg(~21C) and one lining up...

    Does lowering (or raising) Ph have any effect on organic stain removal?

    Very ugly indeed. Thanks Allen. I will try the 'shock' brushing in a test area on one of the darker stained spots. Using caution to avoid further damage as you suggest. If I gain any ground I'll take a pic. This debacle is another lesson learned the hard way.

    Does lowering (or raising) Ph have any effect on organic stain removal?

    thanks, I forgot PH invalid at high FC. Here are some pics. When I mentioned feeling the brush rise up as if going over a raised area that only happened at a couple places. Mostly it feels flat as I brush.
