Buy regulating valve water1

Everyone should take the time to find their main water shut off valve. If a pipe bursts, an extra two minute delay can result in 30 or more gallons of spilled water. That is roughly the equivalent of a bathtub full of water. That much water, inside your home can cause a lot of damage. Being able to find the shut off valve and a wrench quickly can save you thousands of dollars of damage. Many homes have additional shut off valves that can shut off localized sections of the water supply. For instance, where the water main enters your house, you will often find a hose bib and a shut off valve. In cold weather locations, the shut off may be in the basement or inside the house, possibly under the kitchen sink or under a closet floor. This valve will typically shut off all water inside the house but may leave the outside plumbing unaffected (such as hose bibs, sprinklers, accessory buildings). This valve is most often a rotary type. We recommend that you open and close it once a year to help prevent it from seizing in the open position. The name is Temperature Pressure Relief Valve (TPR valve). This safety valve releases water (and thus relieves pressure) if either the temperature or pressure in the tank gets too high.  These valves are very important.  Water heaters can become bombs if the pressure gets too high and these valves fail to work. These valves are cheap and there's only one problem replacing them -- sometimes they're hard to unscrew. The other reason for the TPR valve to run water is high pressure in the water heater tank.  This is usually caused by one of two things -- high main water pressure (water district or well) or a back flow prevention/check valve. Most homes which draw their water from a municipal supply will have a water meter and shut off valve grouped together. That water meter is often located near the street, in an under ground access hatch. Lift the cover and you will find either a handle or a valve with a straight metal flange across the top. The handle may be rotary, like a manual sprinkler valve or it may be a paddle. Turn the rotary or paddle until it won't turn any further. Valves that have a metal flange require a pipe wrench to operate. This type of valve closes with just a quarter turn. If a wrench is required, we recommend leaving a wrench near the valve for emergency use. Many homes have additional shut off valves that can shut off localized sections of the water supply.
