high/low pressure in tub.

Okay so we purchased this new house about a year ago. THis issue has been puzzling. Once in a while the pressure in the tub both coming out of the shower head and the faucet itself in the tub come out wit a huge amount of pressure. When the faucets are turned up the pressure out of the shower head is so greta it almost hurts on your back. The sink is about 4 ' away from tub. This faucet as well as the rest in the house do not seem to be any different in pressure. Now, this high pressure episode lasts a few weeks and then it seems to be greatly reduced ( about the same pressure as our old house was) and seems more normal. The reduce pressure portion lasts a few months and then the high pressure is back. Since we moved in last September the high pressure incident has happened about 4 times in the past 12 months. I am wondering if this could be a problem with faucet itself. It is an older style 2 handle faucet. Probably 15 + years old. I would rather have the high pressure all the time but it is puzzling when no other fixtures seem to be experiencing this. THx for the help.

Are you on city water or do you have a well? Knowing this will help us figure out why you have higher pressure sometimes and not others.

Here's one guess why you might have higher/stronger pressure at your tub/shower: Relatively modern faucets have flow restrictors. So, even with strong water pressure any faucet with a flow restrictor will probably feel like it has "less" pressure. If your tub/shower has an older faucet it might not have a restrictor so you feel the full flow & pressure at that one fixture.

Okay it is city water not well water. So maybe at certain times the city is supplying higher pressure and that could be why I am not seeing it. The sink faucet in bath is new as i put that in 6 months ago. The kitchen is looks very new as well. I guess to be sure I could put a pressure gauge on outside spigot and see if there is a difference.

Flow restrictions actually cause higher psi and less flow..

The issue I think in your old two handle shower faucet may be a loose washer..

Can you take a pic of the faucet?

Next time you get high or low presuure open and close the hot and cold side a few times. see if you can get the pressure to vary each time..

Often what you may hear with a loose washer is a machine gun sound. tat tat tat tat tat.. Thats the washer moving around in there..

Could be a whole house reducing valve issue but you would get the symptoms at all faucets...
