Under Pressure! Watch Out For Excessive Water Pressure That Can Burst Cheap Water Supply Lines.
The Uniform Plumbing Code (UPC) calls for water to be delivered to homes for domestic use at between 35 and 80 psi. Many homes today are seeing 130 or more psi and it is causing burst water supply lines and hoses that run from the walls into appliances. Think about all the supply lines you have. Every sink has two, the toilet, dishwasher, clothes washer and ice maker each have one. Each of these are “serviced” by supply lines which can fail over time and cause water damage. Every year excessive pressure causes about $800 million in flood claims.
What To Do! When you turn on your faucet do you sense that too much (wasted) water is delivered forcefully? If so, call a plumber who will test your lines for excessive pressure. (all about water regulators) You can also do it yourself for (less than $10) at a home center by buying a basic pressure tester. A fancier one will have resettable needles that will record the pressure range allowing you to see what happens to the pressure when you aren’t watching (such as overnight). They will usually cost around $25.
If your appliances and plumbing are more than 7 years old you may want to replace the supply lines with more high tech hook-ups such as “Flood Safe Connectors” [
Ice Makers are the fastest growing source of problems as the supply lines provided at installation can fail quickly with fluctuating water pressure. High pressure separates the plastic line from the fittings and shut off valves.](“http://www.watts.com/pages/whatsnew/floodsafe_connectors.asp”)
