    What is the difference between a 3/4 hp pool pump and a 3/4 hp booster pump?

    I have a Pentair Kreepy Krauly Legend pressure side pool cleaner. The manual does not give pressure or flow requirements for the cleaner - just says to use a 3/4hp booster pump. I have a 3/4 hp Pentair Whisperflo pool pump available. Is there anything different (pressure or flow) between a...

    Pentair INTELLIpH - how do you reset the fault history?

    My IntellipH had a bad motor. I replaced it this weekend. Does anyone know how to clear the "fault history" (the XX Didn't Dose)? Is there a service mode (maybe entered by holding two buttons at the same time. etc..) that will allow me to reset the fault counter to zero?

    Do I need to get all the Black Algae out? Can I go back to normal chlorine levels now and start swimming again?

    I've been doing the SLAM for a week now. I have been scrubbing and keeping FC levels up to around 24ppm (CYA at 70) all week. I have reduced the amount of black Algae spots by 80 to 90% but it's not gone completely. Water is clear. Can I just go back to normal chlorine levels now (5 to 7 ppm)...

    Black Algae - doing SLAM - questions

    My pool has a lot of Black Algae. I guess I didn't pay enough attention to the pool chemistry, and now I have to deal with it. Usually I'll get some green algae in the summer months and its easy to brush away. I have been doing the SLAM (My FC is at 24 and CYA is 70). It's been three days now...

    my Polaris 360 goes to far corner of pool and gets stuck there - should I go Robotic?

    My current cleaner, a Polaris 360, just goes straight across the pool from its wall connection to the far corner where it gets stuck in the corner of the pool wall and sun shelf. I've tried setting the water jet nozzle located on it's rear end at different angles and directions - but this...

    IntelliChlor not displaying salt level in IntelliTouch

    I have a Salt Cell (IntelliChlor IC40) connected to a Pentair Acid dispenser (IntellipH). It used to display the salt reading correctly (i.e. like 3000) in the IntelliTouch display and IntellipH display, but now I just get a 0 salt level. So I removed the IntellipH and just connected...

    Who makes a fully sealed underwater pool light?

    I've given up on my two color-changing SAM lights. They keep getting water inside and that ruins the color wheel motor and stains the lens. I have repaired and resealed it several times over the years - now I want to replace it with something that will not leak. My gunite pool has the standard...

    Any tips or tricks in pulling old wire out of long run of buried conduit?

    I have a raised spa on my pool with a 4 button spa control. The spa control is hardwired to my pool controller about 100 to 125 feet away. The wiring runs through buried 3/4" conduit and has been in the ground for 10 years now. I tried to pull the old wire out (planning to tie a "pull string" to...

    Broken flange on waterfall fixture - what glue should I use to repair?

    The flange or hub on the back of my waterfall fixture cracked. I was able to remove the spa hose and the flange came off. The flange looks to be glued together at the factory. What kind of glue should I use to reattach the flange to the water fall fixture (it is PVC). This is "face to face"...

    PVC pipe from Spa Heater melted - why?

    I was out spraying the weeds around my pool pad and I noticed something strange - the PVC pipe from my Spa Heater looks to be melted. This Heater was just installed (self install) at the beginning of the year and has only been run twice (setup and testing). I don't see anything in the manual...

    Cal low, Cya low, chlorine good but seeing green algae

    I've been brushing away green algae almost daily. I see it on the walls (even had some on the cleaner hose). I wonder is chlorine is not working because CYA is low. I have a SWG pool and chlorine output is good. I have a muriatic acid injector (Pentair IntelliPH) I also just put a "chlorine...

    Sun is damaging the fiberglass on my filter housing and pump - surface is chalky ...

    The fiberglass on my pool filter and pump is being damaged by the sun. When you run your hand across the fiberglass it wipes off like a powder. And it does make my skin itchy like fiberglass insulation will. I don't have much options as far as protecting this equipment from the sun (I can't...
