    Sand filter pressure rises with use then returns to clean pressure with OFF/ON cycle?

    My sand filter has had odd behavior that I wondered if anyone else has seen. The gauge goes to zero when off and is around 10psi when the pump is on and the sand is clean. If I run my suction side Kreepy Krauley after not having cleaned the pool for a week or so (there's small leaves on the...

    Do CoverStar automatic covers come with a cover pump?

    When my CoverStar cover was installed 2.5 years ago, I was given a Little Giant cover pump. It kinda showed up one day amongst the clutter and I'm not certain if it was part of the cover package or if it was something that the PB threw in. I don't remember seeing it as a separate line item in...

    Someone dumped this Hayward Bag Filter in the alley behind my house

    I was out of town this last weekend and today I go behind my house and there's this massive filter laying on it's side in the alley. Not more than 5 feet on the other side of the fence is my pool. Now Seattle doesn't have a high concentration of inground pools and the likelyhood that someone...

    Pool pump quandary

    My current pump is an antique bronze Jacuzzi driven by a 1hp 220V 56C motor (possibly the last one on the planet). The 56C means it doesn't have a screw-on impeller, it has a keyed shaft and the motor shaft doesn't even enter the wet end of the pump. It runs pretty quiet and I've rebuilt the...

    Plaster dust after bringing CH down

    For a couple of years I had been living with a CH in the 475 to 525 range. Wasn't too much of a problem to work with; my CSI hovered around zero give or take a couple of tenths. This last winter we had a lot of rain and I've been able to use rain water so I'm now at the 275 point and my CSI...

    Japanese Onsens - in Japan

    Just came back from 2 weeks driving around central Japan - the Japanese Alps. Water runs everywhere. The Japanese use an enormous amount of concrete to control the flow. Everywhere you go there's water falls and runoff channels with water cascading down. It is amazing. The other thing that...

    CoverStar cover trips GFCI, motor appears bad, how to prevent in future?

    Starting a month ago, my CoverStar started tripping its GFCI when being closed. What started as 1 trip per closing has become many trips per closing. Replacing the GFCI had no effect. Measured the circuit wiring without the motor connected with a Fluke handheld; it was over-range (>40Mohms)...

    Simple repair for Kreepy Krauly regulator

    I've had a Kreepy Krauly for a long time, and the vacuum regulator, where it's constantly connected and disconnected from the cleaner hose, got brittle and developed a split right at the connection snout. The plastic is real thin there and realized it wouldn't be long before a section broke...

    Best eyeball return for flow

    A posting by ifyjetzzz, concerned about only having 2 returns reminded me of a question I had. I have a 16' x 40' pool with 3 returns. One return, in the deep end short wall is pointed down to promote mixing flow. The other 2 returns are on opposing ends of the two long walls, and I have them...

    Post Halloween Weirdness

    :stirpot:I have an auto cover on my rectangular pool. I use a Little Giant cover pump positioned towards the shallow end of the pool (because that's where my closest power outlet is) and I run a hose to the other end of the pool where I leave the cover open an inch for the hose to drop down a...

    Jandy Lite 2 millivolt heater not starting

    Every season my Jandy Lite 2 millivolt heater is a bear to start. Sometimes I find something wrong like a bad pressure switch or a low output generator. But even after replacing those parts, and with everything, measuring fine through the whole safety and control loop, on the first startup of...

    Repair of Little Giant APCP-1700 Pool Cover Pump

    I have a Little Giant pool cover pump. It’s a model APCP-1700 and it’s a bit of a pricy pump, going for around $140+ online and likely $250 at a pool store. I noticed the pump wasn’t automatically starting unless I gave it a sharp tug on the output hose. It would then turn on and complete a...

    Is there a "My Posts" link like the old forum?

    Is there a "My Posts" link like the old forum so there is a one-click way to check and see if someone has answered your question or contributed to one of your topics. The changes look great and are pleasing on the eye. G

    Will filter sand sitting on plaster over winter cause harm?

    I have an internal leak of sand from my sand filter that puffs out a little bit each time the pump starts. It's not really noticeable after one or two starts but eventually a small pile develops beneath one of my returns. During the summer when I'm vacuuming frequently there's hardly evidence...

    Anyone use a solar cover with an auto-cover?

    Wonder if this has ever been tried. It's for next year's season. I had solar covers for many years. I found they gathered and retained heat very well. I now have an auto-cover which is wonderful for keeping the pool clean and convenient to open and close but worthless at retaining heat. I...

    Cleaning your test block

    Just thought I'd mention that although it may be necessary to get more aggressive, I noticed a simple rinse in hot water was all that my color test blocks needed to clear up. I do all my testing outside, and my blocks are just rinsed in pool water. Over time they've gotten a little cloudy, but...

    Fire in my pump room partially melted acid jugs

    I had a fire in my pump room that, by absolute luck, was noticed by a mason working on my deck. He put it out with water. I wasn't home at the time. Could have been a disaster. The fire burned a 4 pack box of gallon 20 baume muriatic acid. The top portion of the jugs are melted and...

    Can Calcium be removed from water using sequestrants?

    I thought I'd split this inquiry off from the post linked below so as not to sidetrack that threads focus. http://www.troublefreepool.com/want-to-add-ca-without-clouding-pool-t63130.html I've been a member for a while and seen dozens and dozens of posts about high calcium levels and scaling...

    How I fixed a crack in my multiport valve

    My old multiport valve was hard plumbed to my filter. When I replaced my laterals I thought I'd convert to a union style mount for easy future disassembly. Someone had goobered one of the threaded connections to the valve with silicone, so in hindsight I should have suspected what I was soon...

    Do sequestrants bind calcium & release it as they degrade?

    I've watched my calcium level slowly increase from 280 to 380 over the last month and a half and I was wondering if this can be partially explained by degradation of a sequestrant (Jack's Purple) that was added back then. I've added no water or chemicals other than straight bleach and muriatic...

    Buyer beware

    http://seattle.craigslist.org/est/for/3769615326.html Noticed this pump for sale on Craigslist. It could be an innocent mistake, but the title and description call it an IntelliFlo and it's even shown in an IntelliFlow box, but it sure looks like a much less expensive WhisperFlo to me. I sure...

    Can I shut off my pump for a week without a problem

    Would it be Ok to turn off my pump for a week if I'm going on vacation. Pool will be fully covered so no contaminants can get to the water. Current pool chemistry is: pH = 7.5 FC = 3 CC = 0 TA = 90 CH = 320 CA = 40 B = 45 Temp = 70F Water looks crystal clear I was going to lower my pH a...

    All u wanted to know about expansion joint foam filler cord

    I happened upon the manufacturer's site for a company named Backer Rod who makes backer rod products . Backer rod is apparently a trademarked name and a common name (Kleenex/kleenex) for the extruded foam cord you stuff down into your coping/deck expansion joint before you apply sealant. The...

    A couple of positive vendor experiences

    I just wanted to acknowledge 2 positive vendor experiences (3 if you count the fast service provided by the TFTestKit store). First off, I needed a part for my antique American Products 24" sand filter. Among dozens of online vendors, some whose site's said they had stock, none really had or...

    Are diagonal and side wrinkles in auto cover normal?

    Here's a couple of photo's. I had the installer return to check on this and he said that all alignments were good. My water level is even with the ledge that the front bar sits on when it's open. The front edge also stops square with the pool when open and closed. It's hard to see, but in...

    Deck to coping expansion joint sealing

    I need to select an expansion joint sealant to apply between a concrete deck and granite coping. It looks like polysulfide rubber has long been used for this and I've found both positive and negative reviews on this forum. There's also acrylic sealers that have very mixed reviews. Someone who...

    Why are Jandy valve handles opposite most other valves?

    This is more a curiosity than a problem but why is it that Jandy pool valve handles are positioned 90 degrees from the manner in which most other valves operate? The best example would be a Jandy 2-way valve, in which the valve is open when the handle crosses the pipe and closed when the handle...

    Fine point about threaded pump fitting – very long story

    My PC replaced almost all my plumbing during a pool refinish but kept my existing pump, filter and heater. At first startup, I was getting a continuous bubble stream at my returns and my sand filter would fill with air in a few hours. Hadn’t done that before the refinish. PC told me it was...
