Booster Pump Needed for Re-Plumb?

[lblanketx]

Currently my polaris is sitting in between my pump and sand filter which means I have to constantly change the filter screen on the polaris to keep it moving. That also means that with all of the energy I'm using to pump water out of the pool, I'm only filtering 1/2 of it while the other 1/2 goes back unfiltered through the polaris. I was thinking about re-plumbing so all water goes through my sand filter first and then my Jandy Valve will come after the filter allowing water to flow in one direction through the chlorinator and back into the pool and in the other direction through the polaris. This would seem to be much more effecient.
My concern with this, and my question to the experts in the forum, is will my polaris now suffer from lower pressure since I've moved it down the line and will I now have to install a booster pump to maintain enough pressure to keep the polaris moving?

Appreciate any and all feedback.

The booster should have been installed after the filter in the first place so what you are suggesting is a good idea. The purpose of a booster pump is to raise the pressure and they are designed to be placed after the filter so there should be no problem.

But I currently do not have a booster pump. The polaris is powered by my main pump currently and what i want to avoid is moving the jandy valve after the filter and suddenly needing a booster pump to keep the polaris moving.

Ah, sorry I missunderstood.

What is the model# of your cleaner?
What model pump do you have?
What is your clean filter pressure?

A polaris 360, 165 & 65 don't require a booster so they should work fine post filter. A booster cleaner such as 480, 380, 280, 180 might not work post filter but it depends some on your setup.

The branding on the bottom has rubbed off so i cant quite tell but it looks like a 380. It has ribbed hosing. Unfortunately, the writing has worn off the pump as well. All i could make out was C-Fab 1.5HP. Clean filter pressure is just over 10PSI.

Thanks for the advice, I really appreciate it. Think i'll take a stab at it this weekend and if the polaris slows, I'll just have to add the booseter or put it back the way i had it.

Again, Thanks for taking the time to give me some advice.
