Have seen this on more than one occasion. Issues…???
1.) Metals reactivity/compatibility problem would be possible...valve body is copper or brass, most likely. What's the material constitution of the adapter? Galvanized? Of course, one would hope that the unit was working well enough for this not to be an issue in any case (i.e. infrequent or never discharging).
2.) The "plastic" pipe used as a discharge line...PVC or CPVC? CPVC (if I recall) sports a higher temperature rating (typically 160+ degrees F), whereas PVC's temperature rating is lower.
3.) How is the plastic discharge line fixed into the adapter fitting? Compression, thread or glue? Longevity and security could be issues if the plastic pipe isn't securely (ideally threaded) fixed into the adapter.
4.) Perhaps issues with local code(s) or customary local trade practice(s), i.e. "we DON'T use plastic for this purpose, etc."
Did I miss anything?
