Product Q&A
5 QuestionsQ: Can this be installed on older one pipe (1 1/4")steam radiators?
Asked by Ed 12 years ago
Add your answer
If all you want is to do is turn the steam on or off, then yes. If you want to use it as an automatically adjusting thermostatic valve, then no. Here is a page that explains very clearly how a one pipe steam valve needs to work. http://www.fiainc.com/documents/10-08Canyoureallycontrolaone-pipesteamsystem.pdf Here is an example of a thermostatic steam valve that should do the job. The reviews and questions listed for it have a lot of good details that will help you further. http://www.supplyhouse.com/Honeywell-V2043HSL10-1-8-One-Pipe-Steam-Thermostatic-Radiator-valve-includes-air-vent I hope this has been helpful. Good luck!
Q: do you need to drain the water from the heating system when you install these side mount TRVs
Asked by 15 years ago

Verified Reply- PexSupply StaffYes, you will have to drain your system down when installing the valve.
Yes you do or you will have a puddle on your hands! I try and just drain down the system to just below the radiators that I am working on so I do not have to deal with bleeding the air out of the entire system. You can figure out if the water is low enough by just cracking the union fitting where the valve attaches to the radiator and if it drips, you are not low enough.
