    PoolMath app feature request -- individual measurement history

    Please let me know if there's already a way to do this, or move this thread if there's a better place. It would be really nice to be able to look at the logs for an individual measurement -- for example, to click on "CH" and see just the logs of CH measurements. I measure FC and pH often, of...

    Dolphin/Pentair filter and warranty question

    So the 11 year old booster pump for our trusty Polaris 280, affectionately named “Splash” because, well, he often comes up to greet visitors a spray from the tail sweep, seems to be done (longer story about attempted repairs that reduced a big leak but now have it seized up). While I could...

    Injecting liquid chlorine before SWCG

    I recently installed an SWCG (Camilar CMARSHA40-3Y after seeing a good deal at $625), and it's working so well that I've forgotten about the Stenner pump I was using :-) I have a 15-gallon drum with about 8 gallons of 12.5% liquid chlorine, and the question is -- is there any reason I can't...

    Feeding Stenner pump straight from MA jug

    I just installed an SWCG and am considering whether to repurpose the chlorine Stenner pump for Muriatic Acid injections. I have a 15 gallon drum that would have to be emptied and cleaned, but don't really need or want to keep that much MA around, nor do I really want it inside the pool...

    Account doesn't stay logged in

    Anyone else having this issue? Every time I come back to troublefreepool.com after an hour or so, I have to log in fresh with username/password. Yes, I'm checking the "stay logged in" box, have checked cookie settings and cleared cookies. I've tried several different browsers, all with the...

    Stenner pump remote control/home automation

    I am about to install a Stenner pump for chlorine, and am looking for timer options that I can control remotely -- I generally bring a water sample in to the house at night and test it. I'd like to pull up an app and adjust the chlorine delivery for the next day without having to go back out to...

    Replacing Pentair CCP drain port with a valve and hose attachment

    I thought this might be of interest to some people -- I have a Pentair CCP420 filter on a concrete pad with the pumps, and opening the drain makes a big mess everywhere, so I wanted the ability to connect a hose to a better location when cleaning the filter or draining excess water from the...

    Connecting light with cord&plug

    I am replacing my 120V pool light with a 12V bulb and a transformer (for a number of reasons, including safety). I'm using an Intermatic PX100 (listed pool light transformer). My question is whether the transformer must be hardwired (via a switch) to the 120V supply, or if I can put a proper...

    Need help with used FAFCO solar panels

    So I’ve been eyeing used solar panels on Craigslist, and yesterday saw an ad for 6 panels being left out for free, so I hooked up the trailer and picked them up. I could use some help identifying them -- they are FAFCO, 4’x12’ (including the headers), and are a split-tube design that’s a bit...

    Pentair EasyTouch 4P vs PL4

    I’ve been looking into an EasyTouch system, focusing on the 4P, but just noticed that Pentair has another newish EasyTouch line -- the PL4 (and PS4 for pool+spa): http://www.pentairpool.com/products/automation-easytouch-control-systems-49.htm...

    Valuing used solar panels

    I've been looking for used panels on places like Craigslist, and found a set that would fit well on the flat shade structure roof I have available -- 6 4x10 Heliocol panels, 8 years old, no leaks according to the seller, comes with connectors and brackets. There's no asking price, just "make an...

    Intellichlor with copper pipes

    I’m currently deciding whether to go with a Stenner/bleach or an SWCG for chlorine automation; it’s tied to a complete electrical upgrade and prep for solar, so the finances get interwined a bit (e.g. an Easytouch with IC40 isn’t much more expensive than a Stenner + SunTouch). This is a 60 year...

    Polaris 280 leaf bag ineffective

    Background: California, no-close, no-cover, water in the 40s currently, leaves almost done falling for the season. "Splash" as we call our Polaris 280 does a pretty good job with leaves, but gets full too quickly when the full brunt of the leaf fall is in the pool. Maybe someday a cover of...

    Ineffective granulated CYA?

    I recently decided to increase my CYA from ~35-40ppm to the 50-60 range, because with our always sunny, often hot days, my daily FC loss is a bit higher than I'd like; last year when we bought the house the 80ppm CYA worked better. I understand the tradeoff of higher required SLAM levels, thus...

    Help! Leaves getting sucked out of pump when turned off

    For the last few weeks, I keep thinking that the strainer basket in the pump is full while looking at it (new pump). When I turn off the pump and open it up, however, there's very little in the basket. I finally watched it closely enough to realize that the pile of stuff is getting sucked back...

    Which way does your filter face?

    (I'm starting this as a new thread because it's not directly related to the pump selection) This may be a silly question, but which way does your filter face? I have a Pentair CCP420 that I put in last year: Apologies for the mess, it all needs a good cleaning, and I inherited most of the...

    Replacement pump recommendation

    Okay, I was putting this off, but our pump is grinding louder and louder by the day, to the point that it’s uncomfortable to be in the pool area when it’s on, and I’m just waiting for the neighbors to complain. Whether it’s on its last legs or not, I think its time is up, so I’m deciding what...

    VS Pump: are there only 4 or 8 speeds?

    I was curious about this; also considering a VS pump to replace a 3/4hp single speed from 2005 -- are the 4 or 8 speeds the number of different settings you can have (e.g 1 hour at speed A, 2 at speed B, etc), with each selectable across a much more granular RPM range? Or is it that there are...

    Pool light old wiring help!

    I need advice on our pool light. This pool was built in the late 50s/early 60s, with a light fed from a metal junction box under the diving board, maybe 18” from the edge of the pool. It does (well did) have a cover marked “suitable for wet locations) with a gasket. From that box, the wire...

    Filter Help

    We recently bought a house with a pool; I think I have the basic chemistry under control thanks to this site, now moving on to address some of the equipment oddities, particularly the filter (and later I will have some skimmer/main drain questions for another thread). Basics: 21000(est) gallon...
