Despite what time of year it is, you can run into major plumbing problems if your water supply pipes are not correctly insulated and end up freezing over due to cold and extreme weather.

So, whether it is Spring or Fall, it is always best prepare for the unexpected and learn how to insulate key components of your home plumbing system. Today we will be teaching you how to insulate your Pressure Vacuum Breaker, so you don’t have to call a plumber in Las Vegas to do it for you.

A PVB is an important aspect of your home plumbing system. This mechanism feeds water to pools, irrigation systems, fountain fixtures, and any other outdoor plumbing appliance.

By following these simple steps, you can avoid a major plumbing disaster by preventing your PVB from being overly exposed to cold or extreme weather:

Step 1: Shut Off Water Supply to PVB

If you are expecting cold or extreme weather the first thing you want to do is shut off the water supply valve to the pressure vacuum breaker (PVB). This cuts off any more water from entering the water supply chamber of the PVB.

It is really simple to shut off water to the PVB. Just turn the main valve (usually located above a water spigot) to the right.

Step 2: Isolating Water to the Pool

If you also want to isolate the water supply going to your pool, you will need to shut off the pool supply valve.

As in the previous step, turn the valve to the right to cut off water going to your pool.

Step 3: Draining the Bleeder Valve

Now that we shut off the water supply to the PVB, we want to drain the water that remains inside the bleeder valve.

This is an important part of preventing frozen or burst pipes, because the little bit of water that remains within the pipe has the potential of causing severe damage to your pipes during harsh weather conditions.

A) First remove the black cap from the Bleeder Valve by unscrewing it counter-clockwise

B) Then, use a flat head screwdriver, insert it into the groover of the bleeder valve.

C) Then you want to turn the groove of the bleeder valve a quarter turn to the left to the relieve the pressure in the valve. This ends up relieving the water in the valve and prevents the valve from failing when it freezes.

Step 4: Installing Foam Insulation on Pipes

Now that we have stopped the water supply to the PVB, as well as drained the remaining water within, it’s now time for installing some foam insulation. If not properly insulated, the PVB could freeze over, or in the worst case scenario, end up bursting. If this is the case you want to call an experienced Las Vegas plumber immediately.

(Disclaimer: For this video, we are using a piece of PVC pipe as an example on how to correctly insulate your pipes.)

A) You are going to open up the foam insulation and place it around the pipe. The insulation should fit nice and snug around the pipe.

B) Now use 10 Mil Tape to wrap around the insulation.

Insulating Pipes

By doing the previous steps, you have correctly insulated your outdoor pipes in case of extreme weather and freezing temperatures. But, there is one last step you can take to ensure your PVB does not freeze or burst.

Final Step: Using a PVB Cover

If you know extreme weather is heading your way, you want to head to your local hardware store and purchase a Fiberglass Encapsulated Plastic Insulation Pouch (PVB Cover).

The PVB cover is added protection against freezing conditions and will help in preventing any damage to your pipes when extreme weather hits your are.

These pouches are re-usable, and extremely easy to install. All you have to do is slip it over the PVB, making sure the pipes are encapsulated within the pouch. Then you can tie the pouch closed, if you wish, to keep it from possibly falling off during harsh winds.
