LWCO for Ultra boilers
I bought this LWCO to install with an Ultra 4 boiler. These LWCO's are required by code. The installation went very smoothly without a hitch.

Pros and one con
Great compact design. Wire harness perfect length. Only con was plastic male threads. Had to change female adapter so unit would not cross-thread.

Easy install
Very easy hook up just remember hand tighten, don't use a wrench or you'll break it. The weilmclain ultra 155 already has a low water Cut off, it may be a little overkill better safe than sorry.
