Having 2 cartridges would be good. You could alternate using one while giving the other a good cleaning. What's the filter pressure now that the filter's clean?
Thanks! I forgot all about that one!PoolGuyNJ said:PS zea3, lithium hypochlorite doesn't have any CYA either. It' just expensive.
The only chlorine type suitable in that feeder is 3" trichlor tabs.

The VS-3050 can be speed limited so that those with 1-1/2 inch plumbing don't have to worry.. I believe you have 2" plumbing, so you will be fine. Your normal use speeds will be much lower anyway. You won't be using the full output capability, nor will you want to. By slowing the motor, it uses less power.
The motor itself is actually desigmed being able to go to controllers that can provide it with sufficient power to be rated at 6 HP. Pentair's controller limits it to 3 HP. This is able to be done because the motor is a 3 Phase 6 pole design. Regular pool motors use a single phase 2 pole design. The Pentair controller creates the needed power digitally using DC pulses in such rapid succession to accurately simulate a utility provided 3 phase power source. Getting 3 phase power from the power company is an expensive proposition. This is how the do it with large AC units, elevators, escalators, large hoists and many other applications. The technology behind it is sound and proven.
Your day time speed will use about 300 Watts. You're currently using a 1-1/2 HP which uses about 1500 watts. The motor for the Intellifow series of pumps uses it's power at this speed (about 1100 RPM) is about 90% efficient. Your current pump motor is about 50% with the wasted energy turned to heat. The casing is hot!.
Additional energy savings come in the fact that slower moving water through pipe has less friction loss.
I expect a flow rate from 30 to 35 GPM which will push enough water to feed the chlorinator. Your current flow is guestimated at 50 to 70 GPM, depending on whether the floor jets are on or off.
At night, Easytouch will change the return path to the floors and turn on the pump to about 2000 RPM, push about 70 GPM to drive the floor system. I expect about 800 watts. For two hours.
The bottom drains are normally open unless you close them fully or partially, like when you vacuum. They are independent of which returns are open.

Wall Return at 14 - good and makes sense
Wall and Floor @ 14 good, makes sense.
Floor only @ 20 Good and makes sense.
No Floor or skimmer @ 30 Doesn't make sense.
Running on the bottom drain and sending to the wall returns should yield a slightly lower than 14 psi result, not higher pressure in the filter. Something was partly closed, like a loose eyeball rolling in the return fittings or a valve not fully open.
The pictures you posted earlier show your skimmer and drain are tied somewhere at the skimmer. My question to you is where exactly are they tied?

The "return" is where the water returns back into the pool. It is the outlet where water enters into the pool from the pump/circulation system. The skimmer is where water is skimmed from the top and goes back to the pump via the suction lines. So the return and skimmer are opposites -- water from the pool goes into the skimmer to the pump, filter, etc. and then back into the pool via the return.JohnPHX said:And just to be clear, the return and the skimmer are the same thing right? I don't want my terminology to get mixed up.

A floor drain also takes water from the pool (like a skimmer, but at the bottom of the pool) while a pop-up is like a return on the floor putting water back into the pool.
