Low water pressure in shower
Recently replaced a moen shower faucet cartridge (1225) that was leaking. The leak has now been fixed however now I'm only getting about half the water pressure I was previously getting. I took it all apart and made sure there was any blockage, and put it back together but same result. Thought maybe I had a bad cartridge so I bought a new one and installed that...but again same issue, low water pressure. I also replaced the shower head and that wasn't it. Any ideas?

Look for a flow restrictor in the shower head.

They are standard now and pull that out.

Not the shower head as I even put the old one which had a great flow on and it also had low pressure. Is it possible to get two bad cartridges?

The rest of the house has normal pressure?

Yeah...just that particular shower and ever since I changed the faucet cartridge due to the old one leaking. I'm tempted to reinstall the old cartridge and put up with the leaking just so I could have decent pressure again.

Call moen for help, they would have sent you free parts too.

Call Moen.

With all the new water restrictions, they are putting quite a few things in these new assemblies to get the water flow down. Wouldn't be surprised if the new one had some sort of limiting device or set screw.

I would swap the old one back in just to know 100% that the problem was in the cartridge and then would call Moen. There is always the chance I guess that when you took one in or out that something got in and blocked the port. Putting the old one in and having more flow would rule that out.

I know they are messing around with water savings as WW pointed out but I can’t see them changing a replacement part from the original. But then again nothing would surprise me.
