Contractor.

My plumber screwed up and left out the hot water relief line from the underground work. My only choice is to go tankless or cut the slab or connet the relief line to the ac condensation line.

Any suggestions

Need to get this fixed ASAP:(

You could direct the T&P discharge to a floor drain,a sump pump pit, or since it's just a safety device that will probably never be used you coiuld simply run a 3/4" copper pipe from the valve to 4" over the cement floor. Good luck, Tom
