I installed a new 1 HP Intelliflo last year and pretty much all of my runtime is on low speed. My Polaris is wired to run only on high speed. The pool is 20,000 gallon inground with an IC20 installed downstream of pump and sand filter. It seems that when I run in high speed, I end up with cloudy...

Ok, folks. I have pressurized the suction lines and blew a little trash back out but nothing major. I reconnected the pump, filled the basket and powered up. Same problem. I guess at this point I have to assume a suction side leak, but I don't know where I would have generated a leak since I...

That had crossed my mind. I was thinking maybe use a water hose to jet the lines, especially thru the skimmer since the lines are easily accessible.

Actually, I did go to recirc to bypas the filter and saw no change. The results being the same is what made me back off from the idea of the filter being the culprit. As for run time, I gave it maybe 5 minutes (the O&M calls for a max of 8 mins to prime).

I installed my new 1 HP, 2-speed pump this weekend. When I tried to prime it, I got alomst no flow. My pool is in bad shape since it has been sitting for awhile. The steps I have taken thus far are: 1. Filled the suction lines with a hose until the water stopped running out of the basket into...

So....I just picked up a Superflo 1 HP 2-speed and an Intermatic P153. The pump came with the manual switch on the power end, I assume to switch between high and low speeds. Should I wire up with the switch on "high" or disable/remove the switch? Surprisingly, the install/O&M paperwork does not...

Being in a similar boat (I'm considering a two-speed pump for the replacement I'm about to do), could I use something like an Intermatic 153 to run the main pump as a two-speed and run the Polaris booster? I don't need fancy as I have no other loads to deal with, and this Intermatic claims to be...

Gotcha. I just wanted to make sure I was on the same page as you. Now for some more info (and if we need to move this I don't mind)... I've been having trouble keeping the pool clean/clear after it really warms up, say after Memorial Day. It doesn't matter what I do with regards to pump run...

Thanks to both of you. The pump housing is crackedand the impeller is locked up so I'm playing it safe and replacing the whole pump unit. Mas: As far as HP, you're loosely suggesting the 3/4 HP motor uprated to 1 HP, correct? Also, I'm interested in how you calculated the loss and flow...

So.... My 1 HP Hayward Superpump died and I need a replacement. I'm trying to determine if I can reduce the pump HP, maybe even as far as an uprated Pentair 1/2 HP. The relevant numbers: 18'x36' oblong (oval with straight sides), 3 ft shallow end and 8 ft deep end approx 21000 gallons IC20...
