Do not ignore fluctuations in your shower water pressure. This could indicate more serious issues than you think, such as cracked or leaking water pipes. Professional intervention may be necessary before the problem escalates into a plumbing catastrophe.
How to diagnose low water pressure
You should test your water pressure if it seems low. The average home's water pressure should range from 45 to 55 PSI (pounds per square inch). A simple pressure gauge can be connected to an outside spigot near the main water supply line to test the pressure. Another place you can test the household water pressure is the cold-water line of your washing machine. Any reading below 40 psi indicates that there is a problem with the water pressure entering the house.
Five Reasons to Lower Water Pressure in Your Shower
Sometimes the problem lies within the home. Here are the top five causes of poor or irregular shower pressure. We also offer some tips on what you can do to get your shower head pressure back to normal. Some of these issues can be fixed by DIY, while others will require professional plumbing services.
Pressure Regulator Devices
Your home's water pressure regulator is likely to malfunction if your shower head pressure suddenly drops without any explanation. This regulator is usually set to maintain water pressure between 45-60 psi. You may need to call a plumber if this happens. Incorrect installation of water pressure regulators could lead to more costly drain repairs.
Home Water Valves
Sudden drops in water pressure in the shower could also be caused by an accidental shutoff of your main water valves. These are the main valves that control water flow into your home. They are usually located in your water meter box. This relatively minor problem can be fixed by finding your home water valve and making sure it is set to "on". Home water pressure can be affected by even slight or accidental "off", The best part about offset home water valves, is the fact that it is very easy to fix.
Showers during Peak Periods
Sometimes low water pressure in shower heads can be due to something outside your home and plumbing system. High water consumption in your area or building could be causing low shower pressure. If this is the case, you can test your water pressure during other low-use times, such as when local water consumption is lower than it is before work or when residents return home from work.
Mineral Accumulation in Pipes
Mineral accumulation is a common reason for low shower pressure in older homes or homes with old plumbing systems that use galvanized pipes. Mineral deposits and accumulation can be avoided with little effort. It can also be difficult to remove mineral deposits from pipes. You should immediately contact a qualified plumber in your area to repair or replace your pipes.
Pipe Leaks
If you can't identify the source of low shower pressure using any other means and it gets worse, then pipe leaking or fracture could be the reason. These leaks will allow water to escape from your shower heads and other drain fixtures, making it less likely that you can get any more. There is little you can do if your home's plumbing system is leaking. These experts can use video inspection equipment and other tools to assess the condition of your pipes. They will then recommend the best repair options for damaged plumbing.
