Pool was built in 1987, refinished in 2015 with waterfall feature added, and pool deck re-done. There's a 3 foot retaining wall on the back property line, about 4 feet from the pool deck at the closest point. The land behind my property sits down about 3 feet. There are a lot of holes...

I think I'd need to dig out a bunch in front of the pool in order to get fill under there. I have a hunch the water ran along the pool shell and washed out a lot of dirt. I was just hoping the answer would be "Nah, don't worry about it"... I think any backfilling/compacting I did without...

Hi Folks, Haven't posted in a while, because I haven't had any issues. You all helped me get through my first 6 years of pool ownership - switching from tabs to liquid chlorine, installing a new pump & sand filter and finally installing a SWCG. I hope I can get some input on my latest issue...

Thanks for your help! I have a Pentair Superflow 340042 1 HP 2 speed 230v on it's way.

Thanks for the links and the advice! I think I've got it figured out with your help.

Hi folks, I didn't want to clutter this thread (pump-sizing-help-t40222.html) where mas985 gave me some pump recommendations. I'm going from a single speed 230v pump with a mechanical timer to a 2 speed pump & adding an SWCG and trying to wrap my head around how (or if) to re-do the timer. I...

Ah, thanks for the clarification. Both of the pumps you recommend are 115v. I have 230v at the pad & no interest in running 115v out there. Based on a quick look on the net - all of the 3/4 2speeds are 115v. I guess I have to go 1hp?

Thanks for the input. I guess I should mention that: 1) the female threads on the whisperflow return are iffy due to a freeze last winter pushing the threaded pvc out - I've had leaking issues all summer around that fitting and am tired of jacking with it and 2) the motor's bearings are...

Hi folks, I'm in the market for a new pump. ~13000 gal in ground pool. 2" suction line. 1 1/2" return. 24" sand filter. Soon to be adding a SWCG. I currently have a pentair whisperflow 1 1/2 hp single speed. Would like to go to a 2 speed or variable, without breaking the bank. What model/size...

1) Pump make and model. Pentair Whisperflow 1.5hp 2) Approximate age of pump at failure Unknown - pool was built in 1987. We bought the house in 2007. Pump motor failed 4/2011 3) Reason for pump failure. (e.g. motor, leak, housing crack, etc) Motor failed - replaced - pump still going...

It's about 1" x 1". Back side looks the same as front side. The jagged bit at the bottom is where it must have torn off from whatever it was attached to. The setup's pretty simple. No fountains or water features or heater. Equipment: Hayward 300lb sand filter with multiport valve on top...

Anyone know what this is? [attachment=0:26jnlik2]IMG_3263.JPG[/attachment:26jnlik2] I found it stuck in one of the return eyeballs. I've done seal maintenance on the pump, pretty sure it's not from in there. The valve on the filter is only a couple of years old and works fine, so I doubt it...

Hi all, After topping off the pool (we had closed it for the winter) and some spring rains, my CYA level has dropped to 10 ppm or less. I have a leftover bucket of HTH trichlor tabs from the previous owner. Does anyone have an approximation of how much CYA is added over time by the tabs...

Step 13 - Re-install the diffuser with the allen screws. Grease the seal plate gasket with teflon lube, then press it into place (flat side down) on the seal plate. Take your time and make sure the gasket is fully seated all the way around. I had to use a screwdriver (GENTLY) in some spots to...

Step 10 - Remove the old ceramic seal from the impeller and clean the impeller. [attachment=2:23yfgkzz]10.JPG[/attachment:23yfgkzz] Step 11 - WASH YOUR HANDS! Make absolutely sure there's no silicone, lube, etc. on them then wet the new seal with a little water and gently press it into place...
