The Zone Valve Control 306V connects up to six thermostats and operates zone valves to provide heating to a zoned hydronic heating system. The 306V operates a system pump whenever a zone valve opens. Zone 1 can operate either a zone valve or a circulator to provide heat to an indirect domestic hot water tank with optional priority over zones 2 through 6. The 306V includes optional exercising to prevent circulator seizure when not in use, and optional post purge operation of the domestic hot water tank to maximize energy savings. The 306V provides a RoomResponse™ signal to modulating-condensing boilers to optimize comfort while improving boiler efficiency.

The WiFi Snow Melting Control 670 operates hydronic and electric heating equipment designed to melt snow and/or ice from roads and walkway surfaces. The control works with the tekmar Snow/Ice Sensor 090 or Snow Sensor 095 to automatically detect snow or ice and operates a single boiler, steam valve, or electric cable to supply heat to the slab. Boiler return protection is provided to non-condensing boilers using a mixing valve or variable speed injection mixing pump. When connected to the Internet, the Watts® Home mobile app allows the 670 to be controlled remotely.

I turned on the main water to help flush out the main body of the regulator. To keep from making a mess, I used a piece of plastic to direct the water into a bucket. After rinsing out the regulator, I used an old t-shirt to clean out the inside of the regulator.

Rebuilding a water pressure regulator valve is easier than replacing one. I will show you how I rebuilt my water pressure regulator.

The top o-ring, of the basket, needs to be lubricated before being inserted. The rebuild kit came with a small packet of silicone lube. After inserting the basket there is a washer that goes on top of the basket. Then the spring, spring top piece, and regulator top piece screw on top. This is easier if you have the pressure screw turned almost all the way out so there is hardly any pressure on the spring.

The first sign that something was wrong was there seamed to be a loss of water pressure in my house. Taking a shower, seamed like there was hardly any pressure. I hooked up the water pressure gauge and found that the pressure was fine. Running the water, into a bucket, made it easy to see that the flow of water was slower than it should be. I asked a neighbor if he was experiencing any loss in pressure or flow, since we are on the same water supply. He said that his water pressure and flow was fine. That removed the possibility that the problem may have been the water supply pressure or flow. This led me to believe that there was something wrong with my water pressure regulator.

Turn the water back on by opening the main water valve. Check the water pressure with the gauge. Slowly tighten the water pressure regulator adjustment screw clockwise until you have your desired water pressure. I found out the correct pressure should be between 70 and 85 psi. It may be different for you depending on your house and where you live.

This white finish Invita® WiFi Thermostat makes upgrading easy by using the existing 2 wires from any living space to connect to an HVAC Interface Module in the mechanical room. It works with most types of heating and cooling systems including conventional, heat pump and dual fuel while offering fan, relative humidity and ventilation control. The Watts® Home app provides secure WiFi adjustment, remote temperature control and can send email notifications when there are problems with the HVAC system. The Invita WiFi offers a choice of five display screen color themes.

The Smart Boiler Control 294 provides central and indirect domestic hot water heating or volume domestic hot water heating by operating up to four boilers. This can be expanded in groups of four boilers through the use of expansion controls up to a maximum of sixteen boilers. The 294 operates both condensing and non-condensing boilers that are either modulating, single, two, three or four-stage to provide a flexible, cost effective hybrid boiler plant solution. The Watts® OnSite web and mobile applications provide real-time remote monitoring, setting adjustments, and notifications.

The WiFi Thermostat 561 provides precise temperature control of a one-stage heating system. When connected to the Internet, the Watts® Home mobile app allows the thermostat to be controlled remotely. A 7-day, 4-event programmable schedule is available and the early start feature automatically learns to heat up the room by the scheduled time. An Away mode is quickly and easily accessed to provide energy savings when the space is unoccupied. The thermostat supports radiant floor heating and optional floor sensors can be installed to enhance comfort and protect floor coverings.

Before taking apart plumbing, it is important to shut off the main water supply and relieve the pressure in the pipes. My main shut off valve is right beside the water pressure regulator. After closing the main water valve, I relieved the pressure, in the pipes, by opening a water valve and letting the water run until the pressure was relieved.

Once reaching the desired pressure, I let the water run for a bit and then double checked the pressure. I also checked to make sure there were no water leaks at the pressure regulator valve.

I thought I was going to have to use one pipe wrench to hold the main body of the regulator while I used the other pipe wrench to turn the top piece of the regulator, but the pipes going into and out of the regulator seamed sturdy enough.

I should have gotten a large adjustable wrench for the top piece of the regulator, but instead used channel lock plyers.

I used the 9/16" wrench to loosen the jam nut and then remove the pressure adjustment screw. I started loosening the top piece of the regulator by using a pipe wrench. I found that it was easier to use channel lock plyers. Carefully remove the top piece because there is a spring, a washer, and metal piece that will fall out. I found that the main spring was broken and this was probably the main reason that my water flow had decreased. I then used the channel lock plyers to remove the basket from the regulator main body.

I used a water pressure gauge to help trouble shoot the main problem and to make sure I adjusted the rebuilt regulator to the right pressure.
