What Furnace has a T&P Valve?
California SURE has some STRANGE laws. Most of the “furnaces” that I have seen have a high limit control. Where does this “furnace” get the water from to activate the T&P?
I have seen an operating controllers and even a high limit controller BUT a T&P that is AMAZING.
I think I had better learn something about this profession before I make a foolish statement.
By the way THERE IS NO SUCH THING as over protection even if there is NO WATER in a furnance you never know.
That drain is probably there per code, check with local authorities.
An existing drain is a good reason why it stays bone dry, remove it and you may have a wet surprise one day.
I am more concerned about a plastic line running from the furnace T&P valve. If this pipe were ever needed, it could pose a health and safety hazard to children playing close by. Have this pipe changed to either copper tubing or galvanized steel.
