HWH ?s

This from a one year warranty inspection. What do you think about the TPRV and the condensate line?

[Michael Larson]

Discharge of the TPR line isn't exactly visible is it?

This must be out in the country.

Looks like there's a TPR drain line, A/C condensate line and HRV condensate line all going to a floor drain. All seems good to me but you folks seem to pay way more attention to the TPR drain/piping than we do up here; at least nothing is draining onto the floor.......

TPR Discharge piping, 2003 IRC:

P2803.6.1 Requirements of discharge pipe.
The outlet of a pressure relief valve, temperature relief valve or combination thereof, shall not be directly connected to the drainage system. The discharge from the relief valve shall be piped full size separately to the floor, to the outside of the building or to an indirect waste receptor located inside the building. In areas subject to freezing, the relief valve shall discharge through an air gap into an indirect waste receptor located within a heated space, or by other approved means. The discharge shall be installed in a manner that does not cause personal injury or property damage and that is readily observable by the building occupants. The discharge from a relief valve shall not be trapped. The diameter of the discharge piping shall not be less than the diameter of the relief valve outlet. The discharge pipe shall be installed so as to drain by gravity flow and shall terminate atmospherically not more than 6 inches (152 mm) above the floor. The outlet end of the discharge pipe shall not have a valve installed.

That also appears to be the drain for the HVAC condensation pan ('s). Was there a trap before that or after the point the TPR is inserted into the drain?

No drain pan for the HWH either in an area where leakage can cause damage. 2003 IRC:

P2801.5 Required pan.
Where water heaters or hot water storage tanks are installed in locations where leakage of the tanks or connections will cause damage, the tank or water heater shall be installed in a galvanized steel pan having a minimum thickness of 24 gage (0.016 inch) (0.4 mm) or other pans for such use. Listed pans shall comply with CSA LC3.

Obviously the HWH and heater is gas fired. The room appears to be small. Has the area been checked for proper combustion air source?
