    Good afternoon all, My booster pump is on its last legs, it is roughly 9 years old and i believe it is getting water behind the impeller. It sounds very rough and has white scaling coming from the impeller housing. My Polaris 280 has also been rebuilt several times in the last 9 years and is...

    Waterfall feature and WF-28/011774 pump/motor downsizing

    Getting to know my pool a bit more, i decided to tackle another small issue. when we are running our waterfall feature, the pump/motor is very loud. Up until recently, we just accepted it. I decided to examine the plumbing a bit more, and found a valve that was more than half way in the closed...

    Pump/motor and I’ve about had it...

    Long story short: my motor/pump stopped turning. After taking it apart, I found that the seal plate bolts had rotted, allowing the plate to bind the impeller. I installed a new seal plate and re-attached the motor and subsequent wiring. Matter filling basket with water, I turned it on and it...

    4 month old B2984 humming

    I purchased a B2984 two speed in early April and tonight it would just hum then a click sound and hum stopped. I’m thinking capacitor, but is it normal for these to only last 4 months? It is in sun until noon, then shaded. I currently run it from 11-7. Before tonight, it ran normally.

    When is CSI too high? When is it time to refill???

    OK you chemistry experts... FC: 7.5 pH: 7.7 TA: 70 CH: 600 CYA: 50 (slowly going to 70) water temp: 84 CSI: 0.12 City Water: TA: 130-150 (depending on lake levels) CH: 150-180 I understand that TFP promotes a slightly negative CSI with a SWG. I also understand that with a SWG, pH tends to...

    Lowering TA = Increasing CH

    Questions below. A bit of background: Before I found TFP last summer, i did not know how to test water properly (mainly used strips), i let my CSI get high enough that i had scaling in my pool, to include my SWCG. One day, i had white scale flakes coming out of my jets by the thousands...

    Good afternoon everyone! I just wanted to share something my son and i made to keep the leaves/pollen pods/toys...etc out of our baskets in between cleaning. I made these after my motor/pump ran dry for some time, as both of my baskets were full of leaves and pollen pods. feel free to utilize...

    IC40 center blade nearly deteriorated

    My Pentair IC40 has been blinking ‘check cell’ for some time. I’ve cleaned it with the hose and acid according to the instructions. The cell light continues to blink, so I decided to take a closer look. When I got a bright light and shown it into the cell, I noticed the center blade was over...

    Century B2984 HELP!!

    Folks, i am switching from a single speed to a 2 speed motor. Century B2984. While moving the capacitor, to gain access to the shaft for tightening the impeller, the red wire, going from the capacitor to the motor came loose, and i have no idea which prong it goes to. Anyone out there either...

    Strange lights after pressing 'more' Intellichlor I40

    Good afternoon pool world! as you can see from my picture, after pressing the 'more' button, the 20% and 60% lights are lit. The reason for me doing this, is my 'cell' light is flashing green....which means i need to inspect. i cleaned the cell per Pentair's and TFP's instructions, yet it the...

    Winter/cold water CSI

    First winter with TFP... FC 6 CC 0 pH 7.8 Alk 80 CYA 80 salt 3600 CH 360 water temp 40*f CSI 0.42 Question: with the 0.42 csi being ‘potentially corrosive to plaster’ should I allow the pH to rise to 8, to keep CSI on the lower end? I was going to lower it to 7.6 in the morning, but am second...

    Keeping pool open all winter/pump run times

    I'm in Central Texas and keep my pool open all winter (this is the first winter using TFP methods). I've searched and read a few threads, but haven't gotten what i'm looking for (not to say i didn't miss it). Details: 1. I've been monitoring the chlorine and pH levels regularly and they are...

    Level pH for weeks....normal?

    pH 7.7 TA 90 FC 7 (trying to get my SWG% and pump run times to work together a bit more) CC <.5 CH 330 CYA 70 Folks, after following advice obtained in other threads, i adjusted my TA a bit then allowed the pH to 'settle' where it would naturally settle. (Prior to that, i was adding MA daily to...
