Hi all, I recently had a new water heater installed (Bradford White 50 Gallon Natural Gas RG2PV50T6N19). I just noticed that the hot water connection on the water heater is directly connected to copper pipe. Conversely, the cold water connection has, what seems to be, a brass fitting in between the water heater and the copper piping. The previous water heater had brass fittings on both hot and cold connected to copper.

My main question is, is the current setup OK (hot water directly connected to copper)? My understanding is that this can potentially leak to galvanic corrosion? Should a brass fitting been used here for longevity? Pictures attached.

Finally, is the pressure relief valve in the proper position? Should this be completely vertical (pictures attached)?

I hope the installer is licensed and has lots of insurance for liability.

I was taught use 4 inches minimum brass nipples I seldom see hard piped water heater due to seismic reasons here but not unusual for people to connect copper direct not crazy about it , the connections usuall out last the heater but will get a fail from inspector. Tand p looks ok I dont like it that close to drywall where if it drips. pvc venting Im not crazy about it might be grading up ? dont like all the fittings. looks like the expansion tank and copper isnt supported properly ?
sorry more than you asked for I wouldnt be overly worried nor impressed by the install . hopefully price wasent high
