Trust me, finding out where your main water shutoff valve is location isn’t something you want to put off.

Where Is The Water Heater Valve Located

A shut off valve is required, by plumbing code, to be installed on the cold water supply pipe to the water heater . Since this valve supplies water to the water heater, by shutting it off you will also be shutting off the water to all of the hot water pipes throughout the rest of the home.

This valve will also either be a ball valve or a gate valve. Typical practice in our area is for this valve to connect to a flexible supply pipe that attaches to the inlet pipe on top of the water heater.

Because the typical water heater has an average life-expectancy of about 10-12 years in our area, many people opt to install some sort of automatic shut off valve as well. This valve has a sensor which detects water if there is a leak and automatically turns the water off.

Remove Old Sweat Valve

Family Handyman

Hold the valve with a pliers, loosen the packing nut and unscrew the entire valve stem. Peek inside and remove the old washer if its stuck on the seat. Removing the valve stem allows any remaining water to drain out, making the unsweating process easier. Before you do any torch work, make sure theres a fire extinguisher nearby and safeguard the wall with a flame protection cloth. Then remove the old valve and the remaining solder.

To begin, drape the flame protection cloth over the copper tubing and tape it to the wall. Adjust the torch to a small fame and aim it toward the body of the valve. As soon as the solder melts, twist and pull the valve off the copper tubing with a pliers.

Adding Sink Shutoff Valves

How to keep them level. Making this simple change will yield a lifetime of convenience and ensure a quick response.

It shouldn’t be necessary to turn off the water to the entire house just to fix a leaky faucet, but that’s exactly what many homeowners must do. Why? Because they don’t have individual shutoff valves installed under every sink.

If you’re facing the same situation, consider putting a valve on every hot- and cold-water supply tube. The valves will not only allow you to shut off the water to one sink without disrupting the flow to others but they’ll also provide a quick way to turn off the water in the event of a flood caused by, for instance, a cracked fitting or ruptured supply tube.

The good news is that adding compression shutoff valves to an existing sink is a simple, straightforward job that most homeowners can handle. In most cases you won’t even need to replace the supply tubes that run from the valves to the faucet. However, if the tubes are corroded or kinked, replace them with braided stainless-steel supply lines . Standard compression valves cost about $7 each.

Two Conditions Two Valves

There are two styles of compression valve commonly used in sink hookups. When the water pipe enters the sink cabinet through the back wall, a right-angle-stop valve is required to make the 90-degree turn to the faucet. When it enters through the floor, no turn is needed so a straight-stop valve is used.

You must also consider the type of pipe that supplies water to the sink. If it’s made of 1/2-in. rigid copper, you’ll need a compression fitting to connect the valve. If the piping is threaded galvanized iron, use a valve that has female iron-pipe threads.

Here, we’ll show two different installations: adding an angle-stop valve to galvanized iron pipe and putting a straight-stop valve onto copper pipe. Note that angle- and straight-stop valves are available for both copper and iron piping.

Angle-Stop Valve

Your first step is to shut off the water to the entire house at the meter. Drain the system by opening the sink and tub faucets on the lowest floor. Some water might remain in the system, so keep a small bucket handy.

Next, use a wrench to loosen the water-supply tube from the adapter. Break the 3/8-in. compression nut free with the wrench, then twist it off with your fingers . To disconnect the other end of the supply tube from the faucet, use a basin wrench . The long handle of this wrench allows you to reach up behind the sink bowl and grab onto the faucet’s coupling nut.

Where Are The Kitchen Faucet Valves

Under kitchen sinks, there will typically be three shut off valves. The two uppermost valves will be the hot and cold valves for the sink faucet. The lower valve is for the dishwasher.

Conventionally, these valves would connect to the faucet in the same way as bathroom valves/faucets with replaceable supply lines. Many newer kitchen faucets now come with integrated supply lines that connect directly to the outlet of the valves.

In larger, newer homes, you may find an additional valve designed to feed an under-sink water filter or instant hot water tap.

The common rough-in dimensions are very similar to bathroom faucets with the hot valve ideally being on the left side of the drain pipe when facing the wall and the cold valve being on the right side. Of course, there is usually much more space under the kitchen sink, so you will often see these valves in various places.

• Dishwasher/Refrigerator

Refrigerators with water dispensers and icemakers as well as dishwashers SHOULD also have a water shut-off valve, but some may not. For dishwashers, look for a second valve on the hot water supply line that has a horizontal pipe leading away from it. For refrigerators, its usually located at the wall at the back of the refrigerator sometimes hidden in a panel. Valves MIA? Check the attic/basement ceiling directly above/below the appliance.

Where Do I Find My Main Water Shutoff

Around the house, the main shutoff valve is usually located on the outside towards the street. You can trace the water lines back to the main valve or the mechanical area if there is a basement in your home. If the home does not have a basement, an access panel can hide the shutoff valve.

Also, outside your home, there may be a primary shutoff valve. Located on the curbside of the street usually next to the water meter. Some main shutoff valves may need specialized tools to turn on or off.

The dishwasher is also tied into the plumbing system via a drain line. Locate the rubber hose coming from the dishwasher and trace it to the end connection. It may run upward to connect to an air gap fitting mounted to the sink or countertop. If so, loosen the clip or clamp holding the hose to the air gap, and detach the hose.

If the drain hose does not run to an air gap, it will terminate at a nipple fitting on the food disposer or sink drain tailpiece. If so, detach the hose at this point.
