    Pentair Intelliflo VS shuts off at low speed

    I've got a EE background too, so I also opened the controller to have a look. I already had a full set of security bits. ;) You won't get too far. There are some large polar caps that are potted into the housing that must be de-soldered to get to the front of the PWB. I didn't go that far but...

    Pentair Intelliflo VS shuts off at low speed

    The cost of a new replacement controller (with only a 90 day warranty, IIRC) is nearly the cost of a new pump, so I got a new pump and a third-party extended warranty. My credit card paid me the repair cost, I paid the remainder. This happened December, 2018. If you do a web search you will...

    To maintain your pool yourself - or hire out - thats the question

    I fired my once a week pool service 6 years ago and never looked back. TFP is the way to go. However If I was having a new pool built, I'd still use the contractor's recommended service for the first 3 months or so. If anything goes wrong with any part of your new pool the builder will likely...

    Pentair Intelliflo VS shuts off at low speed

    I had the exact problem with my Pentair 011018 at just under 6 years. I found that it worked ok warm but when cold (I'm also in SoCal, so that's below 50F), the vibration occurred after the pump slowed from start mode to low speed. I first thought it was due to an imbalance but it turned out to...

    Relay modification/upgrade possibility?

    When an SSR switches on, there is a voltage drop across the TRIAC junction that’s mostly independent of the load, so a higher current rated SSR will only be slightly cooler due to its lower loss. The data sheet should show a value for "on voltage" at full load or at differing loads. I don’t...

    Relay modification/upgrade possibility?

    Your 6KW heater load is 27.3 Amps at 220V, so it's no surprise the 30A relays are failing. SSRs can be a good solution, but with your high load you need to consider the heat they generate from their internal loss. The data sheet I found on Ebay says 1.6V voltage drop, so at 27.3 amps that's 44...

    Poolvergnuegen Pool Cleaner low wheel RPM

    Take the top off the cleaner and look for debris trapped in the gears. Check that the turbine blades are free to move.

    Strange holes in pool cleaner hose

    Racoons caused the same damage to my hose. Cute & cleaver critters while in a zoo, nasty and destructive in your backyard. Good luck.

    No Cell Power 2?

    If you just re-solder the failed connection it will almost certainly fail again if the relay doesn't fail first. The root cause is very high heat from the relay that is conducted down the heavy lead into the solder joint. The heat comes from the load current (your pump?) passing through the...

    Stenner Chlorine Pump - Installation

    Nice installation. I love my Stenner setup and after 5 years of operation (pool open all year) I've learned to replace the pump tube each spring. If it cracks inside your enclosure you will have a bad day. Also, be careful selecting the tubing & connectors that come in contact with chlorine...

    No Cell Power 2?

    The solder joint failed because of excessive heat from the relay due to oxidized or pitted contacts. You need to replace the relay, Omron G8P-1C4P 24VDC, about $10 from Amazon or Digikey. And yes, you can learn to solder on YouTube but big parts, like the relay can be challenging to remove.

    Best Places to Buy Liquid Chlorine

    I just purchased 10% HDX at Home Depot in SoCal and the price is now $8.98 for 2 gallons. Last purchase in December was $6.86. That's a 31% increase.

    Goldline Automation - Actuator Help

    All the actuators I've seen have a small 3-position toggle switch that sets normal action, off, and reverse action. Perhaps one of your switches is set incorrectly.

    Holy Electricity Bill, Batman!

    If you have a Smart Meter installed for your service, you can go to the SCE.COM site and configure your account to show your usage by month, day, or hour by hour, usually delayed by a day or two. This is really useful to track down surprise usage. There are several low cost devices that...

    Stenner with Tank Mounting

    The white Stenner tubing is not UV rated and will fail quickly in direct sunlight. Stenner also offers black tubing that is UV rated and works well outside.

    Chlorine level varies greatly

    I had similar problems with my Stenner system a while back. It turned out to be an internment suction side leak at some compression fittings I used. I installed a flow meter on the suction side and could occasionally see an air bubble go by. I found and replaced the cracked hose and all was well...

    Stenner Pump stopped working

    You could have a leak on the suction side from a cracked hose or fitting. If you have a duckbill check valve, it could be plugged. If you've never changed your black hoses in 6 years you could have sufficient sediment deposits to plug the line. Depending on how you attached the injector, you...

    Reliable SWG's for under $700??

    If you are using 128 oz of 8.25% bleach every day in your 20K pool that's about 4.2 ppm loss per day. I think their may be a problem with your water, or the bleach.

    Surprised when looking for chlorine in Murrieta CA (SoCal) coming from FL

    Welcome to SoCal. I get my 10% chlorine at Home Depot. I always check the date code and usually find it about 4 weeks old. This varies by store and occasionally some 6-month old shows up. If you are new to SoCal you may not be ready for our power rates. I'm on SCE and was paying as much as 31...

    Add SWG Copper Pipe after Old Heater

    My pool has an ancient Laars Series One heater and has about 30" of copper on the in & out lines, PVC everywhere else. According to the manual: Do not install PVC plastic piping directly to the heater inlet/outlet header. PVC pipe does not have the high temperature capabilities required to...

    Stenner pump problem

    You need to remove all the salt deposits. I take my injector apart and let it soak in diluted acid in an open area. Rinse and reassemble. If the wedge end of the duckbill isn't closed, replace it. Before you replace the injector also check for deposits in the fitting. I was surprised to find...

    Stenner pump problem

    Do you regularly clean the injector and duckbill check valve for salt deposits? I do mine every 6 months after I learned the hard way.

    Problem with Stenner Pump

    Most black tubing is UV resistant and safe to use outdoors in direct sunlight, but most clear or translucent tubing isn't. Also whatever tubing used needs to be chlorine compatible. PTFE is semi-transparent and chlorine resistant but costs about $5/foot. I use a Stenner AK600 flow indicator...

    Stenner Pump priming?

    My Stenner self primes. I have a flow meter on the suction side and can see liquid flow after a few minutes. I think you should look for a leak on the suction side tubing and fittings. If you have a duck-bill check valve it may be installed backwards. Good luck.

    Is this the lighting junction?

    It looks like my pool light junction box except mine (20+ years old) has a brass base. The jacketed cable looks like it's from the pool light. Do a web search for: pool light junction box code The code requires the box to be at least 4" above grade & 8" above the maximum water line. Looks like...

    Help with Jandy Valve

    One direction is your skimmer, the other your main drain. It is likely set for skimming action with a little bit of drain. Move it to the other direction and check that the skimmer is off. Put it back the way it was and label the pipes.

    Here we go again - Variable Speed Pump and GFCI breaker tripping AGAIN ??

    If your reading was 2,000 ohms at 500 volts that would be .25 amps, a massive fail. I suspect the reading was really 2,000 K ohms or 2 Meg ohms, for a leakage of .25 mA.

    CYA Sample Solution (50ppm) Photo

    I use 10 ml of water, 10 ml of reagent. Mix for 30 seconds and let it stand for at least 2 minutes. Then I transfer to the red cap bottle and fill the sample tube until the black dot is occluded. I note the value and repeat until I get a consistent reading. Then I repeat the test with my own...

    CYA Sample Solution (50ppm) Photo

    I got a pint bottle of R-7065 standard last season to calibrate my readings. When I mixed up my first sample I was surprised there was no trace of the black dot or the white background at 50ppm. Nothing like your picture. I've retested several times along with new R-0013 this season with the...
