B-vent pipe.
Cold water pipe.
replace the water heater inlet pipe on the intake manifold on a 3800
the shower and bath water comes from two different places so their is two different pipes. Get the shower pipe checked out by a plummer and they cause fix the pipe.
There should be no more than six inches between CPVC pipe and the exhaust flue on a water heater. If the CPVC pipe is installed too close it can be a safety issue.
A water pipe.
If water is only drawn from the cold faucet, then no, the water heater is not involved. However, if water is drawn from the hot faucet- even for a few seconds- hot water IS withdrawn from the heater, and fresh cold water drawn in to be heated- even if the hot water did not make it all the way through the pipe to the faucet- and the water heater will work to heat that fresh cold water.
There are no hoses that do this. There is only copper pipe, galvanized pipe, or PVC normally use in a home water supply.
There are several possibilities; some of them indicate plumbing problems, and some of them are just consequences of physics. If the ceiling in the room with the shower drips all over during a hot shower, it may simply be that water vapor from the hot water is condensing on the relatively cool ceiling and dripping. If the ceiling in the room with the shower drips in a particular place, then it may be that the hot water pipe is leaking. (It's unusual for the hot water pipe to run through the ceiling instead of running up inside the wall, but it's not impossible.) It's also possible that it's condensation again, but that the condensation is only occurring at a particularly cool spot... perhaps where the ventilation system or a cold water pipe runs through the ceiling above. If the ceiling in the room underneath the shower drips after someone takes a shower, but only a hot shower, again it's probably the hot water pipe. If the celing in the room underneath the shower drips regardless of whether hot or cold water is used, then it's most likely a drip in the shower drain pan.
Called the 'exhaust chimney'. It should usually be a double thickness aluminium or steel tube.
