thank you for your reply i had a drip coming from the bathtub i replaced the cartridge and that stopped that… im not familiar with springs and seats?
Yes, that faucet has two rubber seats and two springs.
But replacing those will probably not correct your issue.
Replace the cartridge again and make sure you use an original Delta part.
Does this pressure drop happen when you run the tub spout ? Or only when you run the shower ?

its the same for the tub and shower… i turn it on pressure is normal for 20 seconds then drops pretty low
Is that when it started the pressure drop ? After the cartridge was installed ?
The new cartridge came out of a Delta package ?
Did you replace the seats and springs ?

no the bathtub was dripping thats the reason i changed it from the beginning.. it fixed that… but it was doing the same thing before the replaced cartridge as well… starting normal pressure 20 seconds lated drops
Replace the seats and springs behind the cartridge.
You possibly have a piping restriction on the hot or cold.
If you have a thermal expansion tank it can be giving you 20 seconds of constant pressure before it exhausts its pressure.
If that’s the case, the expansion tank is fine....there’s a restriction in the piping. Are sure all valves are all the way on.
It’s a guess....

Turn the shower on and the lavatory at the same time.
see if the pressure drops at the lavatory like it does at the shower. Run them both at the same time.

You can also try taking the cartridge out and then turn the water on full force and try flushing it out.

yes it does
You may have a valve partially turned off some place. Or some bad pipe......
A restriction of water flow of some type snd it could be anywhere.
