Your Has Whistling Pipes and You Need to Fix It
Your whistling water pipes can accompany a variety of other plumbing problems, than simply making an annoying sound. Tracking down the whistling noise to a specific source might take some time. But not finding and repairing the cause will often produce significant wear and tear on the plumbing fixtures and appliances in your home, creating even more problems.
Any time the water pressure in the house is too high, it can easily cause the pipes to vibrate, which often produce low or high pitched sounds. The suggested water pressure, from the International and Uniform Plumbing Code Handbook, recommends 40 to 50 pounds of pressure per square inch (psi), for any residential property.
Restrictive Pipes and Washers
Any damage or loose washer, especially those located in toilet valves and faucets, will often create a whistling sound as the water passes through them. Internal pipe restrictions in a section of plumbing will also create a high pitch sound. Often times it is due to growing sediment building up inside the pipeline that reduces the amount of space for water to move through. Sometimes adjusting the water pressure will help dislodge the impediment and reduce or eliminate the whistling sounds.
Extremely High Water Pressure
Most plumbing fixtures and appliances are designed to tolerate water pressures of no more than 80 pounds per square inch (psi). Excessively high water pressure will often cause strain and stress to the water supply lines, valves, fixtures and appliances. Extremely high water pressure will significantly increase the chances of a water line rupture or damage to your household fixtures.
Determining what causes whistling pipes and how you can fix it, is often a situation that requires a licensed plumber that has the needed tools, materials and expertise. Most likely, the problem is behind the wall which will necessitate a high level of skill to remedy the situation.
