Does anyone know if a minirester can cause low water pressure at the faucet?

Depends on what a minrester is.
Never heard of one before.

it is a device to stop waterhammer.

I see no way it's going to lower the flow, Pluged up aireators in the faucet, old steel pipes can though.

And if water hammer was an issue before the mini-restors were installed, some calcification or deposits could have jarred loose and partly blocked the water flow, either with a pipe or at the aerator that joe mentions.

its a 2 year old home. the minirester was insyalled at time of build. i just bought the home and the kitchen faucet is the only place i have low pressure. its also the only place with a minirester. if its not that, any thing else it might be.

Twobtaz:

Unscrew the aerator on the end of your kitchen sink faucet spout. It unscrews by turning it counter clockwise, just like a light bulb.

Now check the water pressure with the aerator off.

that was the first thing i did. its not plugged or dirty. not that. i just cant figure this out. i even turned up the water pressure regulator to the house. still no difference. its only a prob at the kitchen sink. i have a dish washer and garbage disposal . if that makes a difference or not. any advice would b greatly appreciated.

I find it hard to believe a minirester would be the problem -- meaning I doubt it is the problem. Sometimes debris can come through a line and plug up something. I would remove the supply tubes at the base of the faucet and point them to a five gallon bucket and then turn on the water supply valves. I'd be looking for very good pressure to be coming out. Something may have plugged up your faucet internally, or plugging up a supply valve. One question to ask is if the hot water has low pressure as well as the cold water, or if only one of them is the problem.

thanks will try tomorrow. ill let u know.

Yeah, but what are the chances that BOTH the hot and cold supply pipes are clogged with sumfin at the same time? If he took the aerator off, then the line that wasn't clogged would have provided good water pressure out the spout.

Twobtaz:
Is this a single lever faucet or one with two handles?

(I'm thinking that it's a single lever ((probably Moen)) that's not opening all the way.)

PS:
doesn't need repeating, but...
Scratch the minirester. If that's the cause of the problem, then my faith in the science of physics and the principles of logic are out the window and I'm joining a monestary to become a monk. Praise God.

Do note - that isn't what I said.

yes its a single handle.

Well, if it's a Moen, I'd start by replacing the cartridge in it.

Other faucet manufacturers, like Delta, have parts on their "cartridges" that you can replace. What you need to do is buy the overhaul parts for your faucet and rebuild it, keeping an eye out for gunk that may be plugging up the cartridge or restricting it's range of motion.
