It’s no fun when you are in the middle of taking a shower in your Winterthur home and the stream of water slows to a trickle. The most logical thing to blame the loss of water pressure is a toilet being flushed or a washing machine being filled. It is not uncommon for losses in water pressure to be associated with simultaneous water usage in other parts of the home.
But if low water pressure seems to be a constant problem when only one source is being used and there are no other appliances using water at the same time, you may have a bigger problem on your hands.
The first thing to do is to check the source of the water supply to your outdoor faucets. Turn the hose bibs to the fully open position and run the water. Is the pressure okay? If so, you probably have a problem indoors. While you are outside, check for any leaks in the hose bibs or faucets. A leak can cause a loss of water pressure in other plumbing circuits.
Now check the hose bibs on the lines leading to interior fittings, like faucets or showerheads, etc. Is the hose bib turned to the fully open position? Someone may have been playing with the bib and turned it down or off. If that checks out okay, take a look at all of the fittings in your plumbing fixtures. Are there any leaks? Is there standing water anywhere, indicating a leak?
If so, tighten up the affected fittings. If you need to remove any fittings to inspect or replace (i.e. a worn out washer or bushing), make sure you turn off the water supply to the fitting first.
If there are filter screens in your faucets check them for an accumulation of debris and clean if necessary. A clogged screen can greatly reduce water pressure.
Many new homes now come with a pressure regulator, which governs the water pressure going into the home. The regulator is located above ground, usually where the pipes enter the home. The pressures are usually preset by the regulator manufacturer but may not always be compatible to the local environment. If you think that may be the problem, contact a local plumbing professional for an opinion.
A disruption in the piping that feeds water into the home can also affect water pressure, such as tree roots in the pipes
or a break in the line. These problems can only be diagnosed and corrected by qualified plumbing professionals
. Please do not attempt to find and fix these problems as the result may be costly or even dangerous to your health.
Low water pressure can be a drag but it may also only require a quick fix.
