Do these look like good PVC exhaust and intake termination ends for a new tankless gas heater?
I look at that picture ans see loose electrical cables, and damaged lagging on the water pipe,
Is see a messy glue job on the end of the intake, (but some paint will hide that)
I finally see that the penetration through the sheet-metal siding has not been sealed. same as the water pipe...
It doesn't look like a big problem.
