Re: Check valve on Heat exchanger Raw Water Pipe?

Karen Smith


Thats a "wye" strainer.  Definitely an after-market modification placed there probably in an attempt to prevent pieces of a failing raw water impeller from getting lodged in the heat exchanger.  If you take off that plug, you'll find a basket in there to catch solid bits.  Or, given the condition of the outside, you might find parts of a basket!

Not exactly an elegant implementation, but not a terrible idea.
