Do you need to shut off the water heater while you briefly turn off the water main to install shut off valves on sink supply lines?

As long as the water doesn't drain out of the heater somehow, no. What kind of car are we working on...

This is a common complaint with mk2 Golfs, most of which were fitted with a heater matrix bypass valves to prevent the heater matrix from bursting under certain conditions. These bypass valves can fail, cutting off supply to the heater matrix resulting in no heat. Either replace the valves or remove them and fit a heater matrix from a mk3 Golf. These are stronger units and don't require bypass valves.

A directional control(dc) valve is use for selectively connecting the supply passage to the return passage in bypassing relation to the hydraulic motor to interrupt operation of the fan.

A straightforward swap of a like make and model from the existing model, if all the parts,valves, strapping, are in good condition and the codes are met. A licensed plumber in the Los Angeles area will cost about $1200-$2000 for a 40 gallon gas water heater. Including the heater.

Check your water heater to ensure that the valve in the supply line is open. You can test that the water heater is working by using the relief valve at the top, just beware of the potential for scalding hot water to come out if the heater is operating correctly. If you have a full tank, and all the valves are open around the water heater, it may be time to call a plumber.

As long as there are working valves to shut off the hose at the washing machine connection, you do not need to shut off the main. If there are no valves there or they do not work, you must shut off the main before starting and then take advantage of this time to install shutoff valves as well.

All showers need valves. They can be for the water supply, balancing the water and control of the shower. Without the valves, your shower will leak, causing damage to the surrounding areas.

You can buy a faucet lots of places and should be able to install it. Most are held on with nuts that screw onto the tubes the supply lines attach to. Most supply lines have shutoff valves on them or you can shut the entire house off. You can usually change one with just a pair of pliers or pliers and an adjustable end wrench, commonly known as a Crescent Wrench.

Yes, but there still is all the water stored in the tank plus the water stored in the existing hot water lines throughout your home that will eventually leak out.If you intend to install a hot water heater (HWH) yourself and you do not have valves to isolate the existing plumbing then turn off your main water supply, drain the water from your home using the lowest level sink, then attach a hose to the bottom of the HWH and drain the tank. When you install the new HWH install new shutoff valves. (Hint: Check with your local city plumbing and see if an expansion tank is required.)

Saddle valves, also known as tee valves, are useful to easily supply water to small appliances

Could be,Thermostat is stuck open, Coolant level is low, Heater core is plugged (most likely),

All you have to do is install a Y fitting on both hot and cold shut off valves inside the cabinet. The other alternative is to T into the water supply and run new pipes for the other sink.

Terrible idea as the water is heated and the valves are closed there could be a very dangerous build up of pressure and temperature as the T&P is the only safety on these potential bombs. Install an expansion tank at water heater on cold water line to handle pressure buildup.

The source of water into a home has no bearing on the shower temperature. - This is caused or changed by the water heater and any piping and valves between heater and the shower. The fact of the well being source of the water is totally irrelevant in this case.

Shut off fuel supply. Allow to cool. Close the inlet and out let valves. Open the drain valve bottom of heater. Open the T&P to break Vacuum. Have a hose attached to dump water in a safe area. If you are draining heater to flush don't shut off fuel supply. On a power vent heater (pvc venting) you can turn the switch off. On a conventional heater with metal flue pipe turn to the vacation setting (lowest temp setting). when your heater is refilled you can switch on or turn temp setting to original position without bleeding gas and relighting. Waiting for a sitting heater to cool will take hours. You can run hot water in house with heater off until cold. You should not have an outlet valve on a hot water heater if you do remove it. Open hot water in building to vent. Opening and old T&P will weaken the spring even more so if hot water runs through it and may cause it to fail (drip) later with water on. Some drain valves drip later with water on have a 3/4 garden hose cap with washer for valve if it leaks as opposed to replacing drain valve.

The aerator needs cleaning. Replace the supply lines and/or the supply valves, if they were re-used, they may be obstructed with lime scale.

The spout is not leaking, the O ring on one of the valves are. Turn your water supply off and take the valves off and replace the O rings

Heater hose valves may be shut off or perhaps the thermostat may be bad..

Roughed-in plumbing refers to plumbing (water and waste lines) installed for future fixtures, for example, a bathroom in a basement. Stops refer to shut-off valves on water supply lines, required to shut-off the water to repair the fixture that they service. So "Rough-in stops" are shut-off valves on supply lines that are roughed-in. If they were not roughed-in, you would need to break concrete floor (to install waste lines) if/when you decided to add a bathroom to your basement family room.

There should be two valves on or near the top of your water heater. One is for the inlet (cold water) into the heater the other is for the outlet (hot water) out of the heater to your house. They must both be open ( turned to the left or counter clockwise).

Sure you can but make sure you install valves on the the inlet before the pump and on the outlet after the pump. So if ever you need to do any maintenance you can close off the valves to stop water running out.

Septum Valves are installed after the dust collector venturi scrubber , to decrease the pressure of Top gas from the blast furnace to supply it to other processes at low pressure.
