Can return cause pressure to rise by 5psi?

[JenMichelle]

Got everything up and running today, and noticed when I took the standard eyeball 1 inch return fitting off my pressure dropped from 15psi to 10psi. Is this normal?
I have a powerful pump (2 speed) and if it’s on high it does this. I might look into making my own return.

Absolutely if you have only one return. Why do you need to run the pump at high speed?

The standard eyeball on the Hayward skimmer and return kits is 3/4" that might be what you have, here's the larger 1" you can swap in.

I only run on high speed when adding chemicals or vacuuming or to get it mixed up quick. I thought about making my own return with a 90 degree angle or 45 if I can find instructions on here where someone has done something similar. The existing one is a 3/4 or maybe 1 inch, I’m not home to measure.
Does that hurt my system for the pressure to go up that much? I am going to purchase a 1 inch return and see the difference, I just don’t want any long term affects on my system with that much difference! I have never noticed that.

Thank you! I will try that one or possibly make my own.

No harm is done.

Your piping is probably good for 300-400 PSI. Your filter has a pressure rating on it that should never be exceeded. Mine is 50 PSI, to give you an idea of ballpark range for that. Your pump is designed to handle as much pressure as it makes, as long as you don't have any extreme/unusual design elements (like trying to use several feet of half inch PVC pipe at the filter outlet). 15 PSI is not approaching any design limits.

Awesome, thanks for the info! I just wanted to make sure no harm was being done.
No crazy designs or 1/2 inch pvc, all 1 1/2 I believe.

This is what I did, easy to find parts at your local hardware store.
