Low Water Pressure

Pressure that drops suddenly rather than slowly usually points to a leak or a failing valve rather than ordinary old pipe, and it's worth a call.

When this becomes an emergency

What a pro does

Low water pressure has more possible causes here than in most places, from scale narrowing the pipe itself to a pressure regulator that's failed to a leak losing pressure before it ever reaches the tap. A plumber checks the main pressure reading first, then works through the house fixture by fixture to see if the drop is isolated or affects everything at once. Homes tied into drip irrigation or pool equipment sometimes lose house pressure when a valve on that side fails or stays partly open. Water district supply pressure can also shift with time of day, which a plumber rules out before assuming the problem is inside the house at all.

Frequently asked questions

Not always. Water district supply pressure can dip at peak usage times, and a plumber checks the incoming main pressure first to rule that out before looking at anything inside the house.
Yes, if a valve on that side of the system fails or sticks partly open. That draws pressure away from the house even though nothing inside the home has changed.
It can. Mineral deposits narrow the inside diameter of older pipe little by little, and that kind of drop tends to happen slowly over years rather than showing up overnight.
Usually, once testing confirms it's actually the regulator failing and not a leak or a supply issue somewhere else in the line.
