Heating your home can be a chore in and of itself, however by adding a zone valve you can greatly reduce the stress and hassle of this seemingly simple task. A zone valve is quiet simply a valve which controls the flow of heat to a certain area. Odds are if you are currently living in a house with more than one floor, you heating system will be linked up with zone valves. These valves, control the water in the heating system, allowing you to heat only certain portions of your home at a time. When your home is built, a professional will have already installed all of your zone valves into your heating unit, however you will find that a time will come when the zone valve needs to be removed and a new one installed.

Step 1 – Locate Your Boiler Room

The first and foremost step is to find your boiler room. It is within this room that you will find your zone valves and set to work on installing your new zone valve.

Step 2 – Locate Your Broken Valve

This task does require a small amount of time. You need to be sure that you are replacing the proper zone valve to ensure that the time you are investing is well spent. In order to do this, you need to adjust every thermostat within your home and set it to a high temperature, so that all the zones will have heat being transferred to them. Back in the boiler room, you will find that the zones all have levers on them. You should be able to move all the levers freely. On the valve that does not move, this means the valve is closed and broken.

Step 3 – Shut Off Your Water

Simply shut the running water off from your boiler and allow it a few moments to drain out. If you do not do this step, you will find that you not only create a rather large mess, but also you will have caused severe burns to your skin as the water will be incredibly hot.

Step 4 – Remove the Power Head

Take your screwdriver and remove the screws that are located around the power head. This is a simple enough task and should only take you a matter of moments. After you have done this, remove the power head in its entirety.

Step 5 – Remove the O-Rings

Remove the O ring from the pipes and install in its place a new O ring, which you will find with your newly purchased power head. Be sure to be gentle with it. If you stretch it out, it will not fit securely and you will have further problems down the line. 

Step 6 – Align the New Power Head

Take a few extra moments to ensure that you are properly aligning the power head. If you do it wrong you will be forcing yourself to spend a large of amount of money to fix this mistake. Secure the power head into place, and tighten it down. 

Step 7 – Turn On the Water

Turn your water back on and allow it to run through the pipes to ensure that it is securely mounted and that there are no leaks.
