I am new here so please be gentle. I have a 16x32 igp with Hayward 1-1/2 max flo pump. my guage reads 40 psi but returns seem weak. they are hardly seem to be moving water. I have already cleaned the filter. any suggestions?

Welcome to TFP!
What kind of filter do you have? 40 psi seems incredibly high. What was your pressure before you cleaned your filters?

Sounds like a clogged filter........and those filters are only rated up to 50 psi i believe. Before you have a catastrophic failure you may want to open up the housing and manually clean the grids and or give them a overnight soak in detergent then acid bath
I ran the filter without cartridge just to see the difference and it made NO difference stayed at 38 psi
Wait you have a cartridge filter? I thought you had a DE filter. Anyway does your gauge read zero when you shut the pump off?(the gauge is functioning properly)?
maybe I used the wrong terminology. I took out the piece inside the filter that looks like pcs of screening. it reads 0 when off then climbs to 38 I also have an inline chlorinator. when I put on the water slide the psi drops 2 psi
Ok what does your filter normally run for a psi?Its starting to sound like you have a clog some where.
The filter shouldn't be an issue being you removed the DE grid and still had the same high pressure. Sure sounds like some kind of restriction downstream from the filter. Any restrictions before the pump should lower your pressure at the filter, not raise it. You mentioned an inline chlorinator. Some, like Hayward, restrict the opening down to close to 1/2" where the flow goes through the chlorinator. I had a check valve that used to break about every 2 years and get stuck right there. I since replaced the check valve with a Jandy and replaced the chlorinator with a Pentair 320 which has full flow through the chlorinator. How hard is it to bypass your chlorinator to eliminate it as a potential problem? After that it's all just pipe to your pool. How many returns?
Thank you for your help. It turns out the gauge was bad. It now reads 22psi. I guess that's much better
Good to hear. Glad you got it figured out. My filter runs right around 20 so i think your in good shape. Are you getting weak flow from your jets still?
Yes. I got some opinions from neighbors. Whom bye the way are all "experts" at everything. Lol. But it seems I have 6- 90° elbows on the outlet side of filter. I was told there might be friction loss there and to repipe everything to minimize elbows. Does that make any sense?
6 in plain sight? Seems excesive do the pipes resemble the board game " mousetrap" ? Lol. But yes every time the pipe turns 90 degs you do lose flow from friction( the exact amount i dont know)
