An auxiliary drain pan with separate drain.
Condensate drain pipe material.
Stainless steel greatly enhances the pipes ability to withstand the corrosive attack for a longer more reliable.
System application and material usage.
Copper glavanized steel cpvc and pex or pe rt are all approved.
The recommended material to use for a condensate system is stainless steel.
The pipe needs to be made from a material different to copper or steel that won t be corroded.
If amines commonly cyclohexylamine morpholine or diethylethanolamine deae are fed properly to neutralize condensate pipe ph condensate pipes can last.
Pvc piping systems are recognized as acceptable for use in condensate drain systems in all major model plumbing codes.
11 pipe should be of approved materials.
For some reason the installer of the water heater shown below decided that the tpr drain piping needed a vent pipe.
Components of the condensate disposal system shall be cast iron galvanized steel copper cross linked polyethylene polybutylene polyethylene abs cpvc or pvc pipe or tubing.
For condensate drain applications solid walled pipe either schedule 40 or constant pressure rated standard dimensional ration sdr is used.
On some occasions there won t be an outside drain for the waste water to exit out of the condensate pipe.
Condensate switches imc 307 2 3 states that all hvac equipment that produces condensate must have either a secondary drain line or a condensate overflow switch a secondary drain pan with a secondary drain line or condensate switch or some combination of these installations should be used to prevent overflow if the primary drain line blocks.
Plastic with a separate drain installed under.
Because condensate pipelines are potentially subjected to carbonic acid a damaging corrosive element material selection is important.
However corrosion is an issue in steam condensate pipes and many engineers specify schedule 80 steel pipe simply because it takes about twice as long to rust through as schedule 40 pipe.
M 314 2 2 drain pipe materials and sizes.
I don t have an outside drain for my condensate pipe.
Condensate shall not discharge into a street alley or other areas so as to cause a nuisance.
Pvc is not approved because it is not rated for transporting hot water.
The key to this project is to measure out the path of the drain line properly as this will tell you exactly how much pipe material you need.
