Exactly what you'd expect of Taco
Built like a tank and eays to install. If it's like every other Taco product I have in my heating system, it should outlast me. The fast-fill lever is a great feature, but be careful with it. I locked everything down while the lever was set to the 'open' position and inadvertently ended up testing my boiler's pressure relief valve. I did end up using a pressure setting lower than factory, but that will vary from system to system, and the setting is very easy to adjust.

valve
I was upset that a shipping charge was applied. I contact customer service and mentioned that other companies had free shipping. She was not able to honor. Oh well.

Must Need Fix
Just before the cold weather hits I usually service the boiler, after replacing the filter, nozzle and setting the point and assembling everything back together, a leek starter on the valve housing had to shut everything off and drain the water out then the hunt for a replacement and I remember supply house i ordered the valve came a day later installed it and filled the boiler back up and started it up no more leaks as if the boiler was brand new.

5 Questions5 Questions
Q: does this valve have anything to do with water pressure throughout the house, for instance the shower?
Asked by Alex 9 years ago
Add your answer
Verified Reply- SupplyHouse StaffThis device is typically used to feed water into a heating system whenever the pressure drops below a set pressure setting, so it is unlikely. You may have a pressure reducing device where the water enters the building which often has an adjustable pressure feature. This device setting would effect the pressure throughout the house including to the shower.

Q: If you want to decrease pressure do you turn the screw counter closewise?
Asked by Andy 15 years ago
Add your answer
Verified Reply- PexSupply StaffThis valve is factory set at 12 PSI and the range is 10-25 PSI. Yes, to decrease the pressure, you would turn the screw counter clockwise. Please refer to the below PDF for more information: http://s3.pexsupply.com/manuals/1283438475959/38647_PROD_FILE.pdf
