You may have an issues with the hot water coming out of overflow pipe.
Water heater exhaust pipe outside.
Apollopex corrugated the 3 4 in.
For some reason the installer of the water heater shown below decided that the tpr drain piping needed a vent pipe.
In most of the disasters caused by hot water heater pipe leaking from the top the trp valve is involved.
The n the gasses end up inside the home near.
Copper glavanized steel cpvc and pex or pe rt are all approved.
Two pipes are fit in and one concentrical pipe gap which runs from the water heater through the wall or roof of the home.
Combustion air is provided to the gas burner directly from the outside.
With a vent pipe that is too large the water heater does not produce enough heat to sufficiently warm the vent pipe to get water heater exhaust gases to rise out of the home.
Backdraft means the exhaust gasses move downward in the exhaust pipe.
Power vented water heaters work the same as ordinary water heaters but the exhaust gases are blown out with a small fan instead of rising upwards through metal pipes.
Single wall natural draft gas water heater vent pipe cannot be used in unheated areas like attic or garage even if only partially penetrating that space because such vent pipe installation will cause excessive condensation on vent pipe walls and compromise proper drafting double wall pipe b vent type is required.
The heater itself encompasses a sealed cover and does not use any air from the area wherever it is installed.
11 pipe should be of approved materials.
The purpose of venting a gas or oil fired water heater is to completely remove all products of combustion and to vent gasses to the outside air without condensation in the vent or spillage at the draft hood except in cases of downdraft or poor stack conditions.
Water heater ducts may lead directly outdoors or they may tie into a larger vent duct that also serves a gas or propane furnace or boiler in the home.
Apollopex corrugated stainless steel water heater connector was designed for the fast and simple installation of hot and cold water lines to water heaters using pex connections.
This is called a common vent configuration.
In this case the exhaust gases backdraft into the home.
In many cases the exhaust from the larger appliance heats up the common vent improving the flow of the water heater vent.
Instead both systems typically expel exhaust through a pipe that runs outside through an exterior wall.
Instead it is attached with a discharge pipe link with hot water heater.
