        This is the standard mixing valve we use for any hydronic board or field application where we need to step down a high temperature supply to a lower temperature application where a fixed setpoint temperature is acceptable. The Union connections make pre-fabrication and later servicing a breeze. It's worth mentioning that we typically use a downstream temperature guage of some sort in the mixed water supply line to confirm and display the actual output temperature, as no such display is to be found on mixing valves themselves.

        not the same size as old unit

        I bought this to replace an old mixing valve with the same model number but the newer valve was slightly larger so I had to replumb the pipes to make it fit.

              Comments about 1/2" Union Sweat Mixing Valves, 70-145F:

              The Honeywell-Sparco half-inch Union Sweat Mixing Valve develops hot water for domestic use and is great at preventing scalding hot water temperatures from reaching your body. This valve mixes a cooler water supply directly with your hot water heater and produces a comfortable 70° F -145°F hot water supply for personal use. This allows the hot water heater to develop higher temperatures for other purposes like baseboard heat and dish washers. Purchasing this mixing valve through PexSupply was a breeze. PexSupply offers a safe secure web ordering application. They keep you informed when the order was received and shipped and they provide quality products at very competitive prices. DIY (Do It Yourself) folks won't be disappointed if you order through PexSupply.

                                                        This valve replaces a tempering valve from Watts. The new mixing valve,(used with a Morflo hot water heater supplying both forced air and baseboard hydronic heat, plus domestic hot water) allows far greater adjustment of water temperature in the dual use system(keeps domestic hot water at exactly 118 degrees as desired). I can run the water heater at 165 degrees for heating while cooling down domestic hot water to 118 degrees. [...]Would recommend this valve for potable hot water system and would recommend PexSupply. Will do business with them again.

These mixing valves never work right.." I have a brand new Dunkirk Empire II Boiler with coil. The water coming out of the boiler is hot. Can barely touch the pipes coming out and into the mixing valve. Once it hits the mixing valve the pipes are luke warm at best. By the time they run their course and get to the shower or bath in question the water is luke warm at best if not cold. I have tried adjusting the temp of the furnace up with no improvement. The mix vavle is maxed out on the hot adjustment. I dodn't know what else to do. The furncae company has been out to replace mixing valve several times to no avail. Is there a solution? Will this mixing valve work better?? I believe they keep on installing the same Taco valve. Thanks,

You need to pull the green cap off the top of the Taco valve and use it as a key to turn the temperature adjustment part that sits beneath it.

                                                                        My Brother lives in Sharon, CT so I have some experience with water in his area. Basically, on the domestic potable water side of his system, water treatment to prevent fouling of componentry is ESSENTIAL. He totally fouled the domestic side of his boiler's plate heat exchanger for heating his domestic water within just a month or two of having his water softener fail.
                                                                        If that is the situation where you are, failure of the mixing valve, regardless of maker, may happen in as little as a year.
                                                                        Having said that, I haven't myself used the Taco mixing valves, but their other products have proven to be quite good.
                                                                        We commonly use the Honeywell valves in our area because they've always proved reliable, and are readily available.
                                                                        Hope this helps.

                                                                      I am currently using a Watts Series 70A mixing valve. It has not worked as expected and I believe it is because of its' flow rating. It requires a minimum 2 GPM to operate properly. I use lo-flow shower heads in my house that produce aprox 1 GPM each. As a result I am getting fluctuating water temps out of my shower heads. The Honeywell AM1 unit claims to operate with a flow of just .5 GPM. Has anyone experienced fluctuating temperatures with this unit?
