Question DetailsAsked on 12/20/2011

why would the water pressure in my shower change drastically overnight?

for years we've had average water pressure, but out of nowhere and quite suddenly it increased dramatically. now there's so much water coming out our tub isn't draining quickly enough and we're left to shower in standing water.

Do you have the same question? Follow this Question

Hi Shelly,

Your question reminded me of an article that Angie's List Magazine published last year:
Pressure woes plague Indy-area homeowners

Hope it helps!

The pumps from your water supply keep going even when demand is diminished at night. It's like an air compressor. If a tool is being used the pump usually doesn't keep up. Stop using the tool and the pressure builds until it hits a certain limit and then it cuts off. The utility company has this pressure set high so the pumps will not shut off during heavy use. Otherwise, they wouldn't keep up.

A pressure regulator installed by your meter will help but make sure it has a servicable screen that can be cleaned out. Deposits and debris in the water can clog them and force replacement if it's not able to be cleaned. There's not much price difference but plumbers like to use the ones without screens so they can charge you for replacement in 3-4 years when the diaphram gets clogged. I see it all the time and people are unknowingly paying money they don't need to repeatedly. Once is enough.
