    Hayward Multiport and Sand Filter Issues

    I hear you. 😔 I guess I was just praying maybe we didn’t add enough to nuke it. Assuming we now have a bromine pool (and we can’t drain all 35,000 galloons right now)…what now? Aside from burning through tons of chlorine, is there anything else we should know or do?

    What do you think about this procedure for testing chlorine vs. bromine?

    Well, that’s not the news I was hoping for ☹️ I appreciate your expertise none the less. I can not believe the pool store gave us these instructions.

    Hayward Multiport and Sand Filter Issues

    In doing other research this morning, we think we are putting too much flow into the multiport. Our pump runs at 3405RPM on high and 2205RPM on low (I know we can probably change this programming but we’re still new at this). When we looked up a chart for the Pentair Intelliflo VSF, 3405RPM...

    Hayward Multiport and Sand Filter Issues

    Okay water test results: 0<FC<1-2 0<TC<1-2 CC = 0 pH = 7.6 TA = 80ppm CH = 110ppm CYA < 30ppm (pool store said 22ppm yesterday) Sat Index = -0.25 That is everything I was able to test with our kit. Is there anything else? We have always struggled with our cyanuric acid. We add it daily but...

    Hayward Multiport and Sand Filter Issues

    Thank you so much. We did learn about the sock method! We took apart the filter and confirmed there are no issues with the laterals. Like you said, we didn't suspect that was the issue seeing as there is no sand in the pool. The MVP was the first place we looked. All appears well with it but...

    Hayward Multiport and Sand Filter Issues

    Any thoughts on why/how the granules are making their way through? If our chemistry is good but the pool is green, it leads me to believe our filter isn’t doing it’s job. We run it 10PM-8AM every night and during the day sometimes.

    Hayward Multiport and Sand Filter Issues

    Thank you. We’d like to get it apart and take a closer look but yes, getting to it is quite difficult. It seems we’d have to remove the top bulkhead to do so and that one is not leaking so we don’t want to mess with it. Trying to decide to tear this thing apart mid season or deal with the drip...

    Hayward Multiport and Sand Filter Issues

    Hi! We have a Hayward multiport and Hayward S310S sand filter. We are having multiple problems: 1) The bottom bulkhead is leaking profusely (5 gallons in a couple hours). We have tried to clean and tighten the bottom bulkhead (which is relatively new and does not appear cracked) but it does not...
