I have a brand new EC4 head unit that has a yoke on the bypass valve with 1 3/8" straight thread for input and output lines. I cannot find a fitting for it to connect to my 3/4" PEK piping. Can someone help me? I went to a plumbing house and they gave me some kind of brass fitting with an O-ring but it was not right. They told me good luck.
I fixed the problem. Bought a PEK adapter that went from 1"NPT to a 3/4" barb in solid brass. Worked great. Be sure to use pipe dope. Even if you use Teflon tape it will leak! No matter how tight you make it, the joint will leak unless you use some pipe joint compound. The stuff I bought was from Lowes and it cost $7.99. Worked great. Be sure to tighten the assembly in a vice and not on the head unit. That much force could compromise the valve body.
Hi, I have the same unit and need to change some of the programmed settings but can't figure out how to do so on the control panel. Do you have the installation/programming manual for this?
