It could be water friction, or it could be blockage. At any rate, many things can cause low water pressure, from simple things like the shut-off valve being left unopened or a clogged pipe. Knowing what to do about this problem now would be a great help in reducing potential difficulties that could lead to serious plumbing repairs in the near future. Below is an instructional on how to troubleshoot low water pressure for plumbing courtesy of Scotto’s Plumbing in Clearwater.
Step 1: Check all locations in your home whether they have high or low water pressure. Usual suspects would be plumbing in the kitchen, bathroom, outdoor hydrant, outdoor tap and the like.
Step 2: Check the faucet if you only have low water pressure in a particular location, such as the bathroom. Remove the end of the tap and turn on the water. If the water flow is normal then the faucet isn’t the problem. Examine the aerator as well for any pressure drop; clean it and replace the aerator.
Step 3: Examine the hot water heater if low water pressure only affects your hot water. Verify if the shut-off valve is turned on. If the valve becomes turned slightly, it can reduce your water pressure in your plumbing.
Step 4: Look at the Pressure Reducing Valve (PRV). The PRV is usually located on the line where it enters the home. It is shaped like a bell, so it’s easy to identify. Adjust it to see whether it affects water pressure or not. If it is broken, replacement is necessary.
Step 5: Inspect the shut-off valve at the water meter. If it is turned slightly, then low water pressure may result.
Step 6: Replace plumbing in your home. Depending on the severity of the water pressure, it is best to locate for the faulty piping and replace it. If it is an old house, it is best to replace all the pipes since there might be clogs and sedimentation occurring within the piping. This is necessary to return the water pressure back to normal.
Step 7: Scrutinize whether you have a water leak in your house or not. Ask your neighbors if they have water pressure issues, too. If they do, then there might be a leak in the lines. Report this immediately to your local water department for prompt assistance in plumbing repairs.
Also, check your outdoor lines for leaks. Also, check your water meter. If it is considerably more than your usual water usage, it is likely you have a leak. Call a plumber for repairs.
Step 8: Be attentive to when your water pressure fluctuates. Normally water pressure decreases during peak hours of usage, like say in the mornings and early evenings when people get home. If this is the case, then you can do little about it. However, if after peak hours the water pressure is still low, then you seriously need to look into proper plumbing repairs. A professional will help sort out your problem, and the earlier it is fixed the better off you are.
