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.
To properly flush a Rheem tankless water heater, you will need to turn off the power and water supply to the unit. Connect a hose to the hot and cold water valves, then open the valves to allow water to flow through the unit and flush out any sediment or debris. Repeat this process until the water runs clear. Finally, disconnect the hose and restore power and water supply to the unit.
Tubs usually do not have shut off valve for them. You have to shut off the main supply. Depending on how the house is plumbed, you may be able to shut the cold supply to the water heater and that will shut off both the hot and cold or the main line where it comes into the house.
Installing tankless water heater isolation valves in a home's plumbing system allows for easier maintenance and servicing of the water heater. These valves enable the water heater to be shut off independently without affecting the rest of the plumbing system, making repairs or replacements more convenient and efficient.
To fix a leaking hot water heater, first turn off the power or gas supply to the heater. Next, shut off the water supply to the heater. Locate the source of the leak, which could be from the pressure relief valve, drain valve, or tank itself. Depending on the source of the leak, you may need to tighten connections, replace valves, or patch the tank. If you are unsure or uncomfortable with the repair, it is best to contact a professional plumber for assistance.
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.
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.)
To properly flush a Rheem tankless water heater for maintenance, follow these steps: Turn off the power and gas supply to the unit. Connect a hose to the flush port on the unit. Open hot and cold water valves to allow water to flow through the unit. Use a pump to circulate a descaling solution through the unit for about 45 minutes. Rinse the unit by flushing it with clean water for about 5 minutes. Disconnect the hose and close all valves. Restore power and gas supply to the unit. Regular flushing helps maintain the performance and efficiency of your Rheem tankless water heater.
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.
