The Why(S) Of Low Water Pressure

A low water pressure is a sickening problem that often crops up in a household. It makes the household jobs that require water all the more irksome. You would not enjoy taking a shower as the pressure of droplets on your shin will be too light. Similarly, it will take hours to wash the dishes in the sink as the dishwasher may not work. And there would be slew of other issues. But what causes the pressure of water falling from your faucets to go down. Well, let’s find out-
Corroded pipes

Most old homes have pipes made of galvanized steel. These pipes corrode over the years. The corroded matter accumulates on the inside surface of the pipes and reduce its cross section. This restricts the flow of water. But there is a household remedy for this unless the situation is too bad. The corrosion usually builds up behind restrictions in the pipe, such as the angle valves under the sinks, shower or bath valves. Turn off the water to the house form the main supply. Take two wrenches. Open the valve with one of them and use the other one to not let the pipe move. You will see corroded material inside the pipe. Take it out with a screwdriver and restore the valves.
Opening the valves for showers and baths will be a little difficult. As you may not have an access panel. In that case you may have to break out the wall, remove the valve and clean the pipe, then patch the wall. Before you check the valve of the shower, inspect the shower head. Deposits may have accumulated there. If it solves the problem you may not have to rip apart the wall to access the valve.

Faulty pressure regulator

This is device that almost looks like a bell. They are found near the water connection in front of your home. These are pre-set by the manufacture so they do not need any adjustment. However if they have become defective, they can affect the pressure of water. You have to get a plumber to get your pressure regulator replaced in this case.

Debris and mineral build-up in pipes

If the quality of water in your area has a high content of sand, dirt, and pollutants, these will enter your house’s pipes when a water main fractures. Even without a fractured line, some amount of this debris will get inside your pipes with the water and cause sediment built-up. This will block the water from flowing in full-force. In this case plumbing chemicals are used that break down and flush the debris.
Plumbing leaks

If you have leaky pipes in the house then the water pressure will go down. This is because the water is going out from elsewhere instead of coming to the faucet. To confirm a leakage, turn off all of the water taps both inside and outside of your home. Record the reading on the water meter. Go and check the recording again after a few hours. If the level has gone down then water is leaking out from somewhere. You have to call a plumber to get the leak repaired after detecting its location.
Municipal water supply malfunctions

Sometimes the low water pressure in the house may not have anything to do your piping system. It may be on account of malfunction in your area's municipal water supply.

Low water pressure is also caused by valves that get accidentally turned off. A kid playing in the lawn or on terrace could have done it. So make sure that the “home” and “customer” valve are turned on.

If none of these problems is the cause of low water pressure in your house, call a plumber. He will be able to determine the problem and get back the lost water pressure by doing the needful.
