What to Do About Low Water Pressure in the Shower
If the water pressure in the shower seems low, the first thing to do is determine how much pressure is coming from the shower head.
Homeowners who encounter low water pressure in the shower have several options. Although the issue might be a simple fix, such as adjusting the time the sprinklers run so as not to interfere with showering, it could be a significant issue. The problem could involve leaking or cracked water pipes that require professional assistance before causing a home plumbing issue.
While it may be a minor issue, it could also be a more significant concern that may warrant contacting a 24-hour plumber.
Diagnosing low water pressure
If the water pressure in the shower seems low, the first thing to do is determine how much pressure is coming from the shower head. A typical home’s water pressure is 45 to 55 psi (pounds per square inch).
To test the pressure, hook up a simple pressure gauge to an outside spigot near the main water supply line. The washing machine’s cold-water line is another good place to test a home’s water pressure. Anything below 40 psi is low home water pressure and could indicate a problem.
Reasons for low water pressure in the shower
The problem can also lie outside of the home. Several common issues can contribute to poor shower pressure. Although it is tempting to tackle plumbing concerns as a DIY project, hiring a licensed plumber to complete the repair is often best.
Pressure regulator devices
If the shower head pressure drops without a reason, there is a good chance it is the home’s water pressure regulator. The regulator is typically set to maintain water pressure between 45 and 60 psi and may be malfunctioning.
If this is the case, the homeowner should contact a local licensed plumber instead of attempting a DIY repair. Incorrectly installing a water pressure regulator can cause further, more expensive drain repair problems.
Home water valves
The low water pressure in the shower head can also come from the accidental shutoff of the home’s water valves. These valves are the primary control of water entering the home and are found in the home’s water meter box.
To solve this issue, locate the water valve and ensure it is in the “on” position. If it is even slightly in the “off” position, this can significantly change the home water pressure. Homeowners should be able to handle this easy fix.
Mineral accumulation in pipes
Older homes or those with outdated plumbing systems with galvanized pipes may experience miner mineral accumulation, a common cause of low shower pressure. Over time, a homeowner can do little to stop mineral deposits and accumulation.
It is also challenging to remove mineral deposits within pipes. Therefore, contacting a local licensed plumber to repair or replace the pipes is best.
Shower use during peak periods
Low shower water pressure can also come from a source entirely outside of the home. The issue is likely due to high water use within the neighborhood or building when showering during peak periods like early morning or at night.
To test this, test the water pressure at other low-period uses where local water consumption is lower, such as right before work hours or when people are returning home from work.
Leaking pipes
Homeowners trying to identify the cause of low shower water pressure without success may have a leaking or broken pipe. A leaking pipe means less water can reach the shower head as the water escapes.
In this case, contact a local licensed plumber; this is not a DIY project. The plumber will use video inspection equipment to evaluate the home’s pipes and provide the best repair solutions for any damaged plumbing.
Resolving the issue
Whether resolving the low water pressure in the shower is easy or difficult, it is essential to consider the best course of action. The issue may not be the water pressure or valve but rather the integrity of the home’s plumbing, and hiring a licensed plumber will prevent further damage.
