It was made by Dolphin/Maytronics, but was branded as the Pentair Prowler 930. It did a good job, until it didn't. Bad motor and $500+ to fix so I went new for the same price.
Interesting. Why is that unusual? Just a little background. The PB built us an underground drain for our two gutters on that side of the house and tied in my basement sump pump drain tube and dehumidifier drain tube to the same underground drain pipe.Your setup is somewhat unusual. Most people with cartridge filters do not have a valve that goes to waste. So I think he, like me, thought you had a sand/DE filter with a multiport valve.
You may move the valves while the pump is running just try not to starve the pump of water while doing it. I never shut my pump off before turning valves.
That's correct. You'll need to use a coupler to attach a new length of PVC to the union. Make sure you use a union compatible with your SuperFlo pump.I need to cut the pvc that this cracked union is connected to in order to fit new one on, reconnect the pvc pipe to the pipe I am going to saw it off from and then screw the new union to the pump, right?
Each valve actuator has two positions it can move to. It has been that way for a long time.works like a champ! Thanks for double checking me!
Do we know if the feature to modulate valves at different positions is a feature that they finally released on the intellicenter? I poked around a bit, but didn't find anything that stood out. I'd love to be able to set the valve position different depending on what feature I'm using. ex: Valves set in one position for running just the waterfall and set to a different position if running waterfall and deck jets.
What is the make/model of the new pump? Pentair VSF 3
What is the RPM when running the booster? 3K
What is the filter pressure when running on full speed with and without the booster? 20 PSI same with or without booster
The booster should not be making that much of a difference unless you are running at very low RPM. I know. That's why I'm having a hard time understanding why it makes any difference at all. I can hear the air in the booster for the first few moments when it starts and see bubbles coming out of the 280 tail.
I think the booster is a clue, not part of the problem. I'm just not sure what it's trying to tell me. It's almost like the pump can't expel the air from the basket on its own but somehow the booster helps to draw it out. It's a separate line from the booster to the pool. Is there any way the pump could be too large for the 1.5" lines? It wouldn't seem that would matter especially lower the flow rate with the pump.
The app is either flow rate or % rpm. I calculated rpm to be 87% to be at 3k which I use as the reference. Not sure what the flow is at that rpm. If I turn off the booste, the air in the pot comes back, even at 3K rpm.
1. You get algae and need to backwash more than you think.You say I need the valve, but I still don’t know why I would need it.
I was told 1 skimmer can cover 400sq-ft of pool so since this was slightly over, I decided to go with 2. Thanks for the input on the other items.Not so much on circulation but more about dirt accumulating on the shelf.
Yes, any pump can handle that but it may require running at higher RPM $$.
If wind blows right to left, the skimmer should be in the deep end where all the surface debris will end up. Also, with that size pool, 2 skimmers is a bit overkill. But it looks like they already cut out the skimmer locations so maybe it is too late?
