On some occasions there won t be an outside drain for the waste water to exit out of the condensate pipe.
Condensate drain pipe material.
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.
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.
Plastic with a separate drain installed under.
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.
Because condensate pipelines are potentially subjected to carbonic acid a damaging corrosive element material selection is important.
The pipe needs to be made from a material different to copper or steel that won t be corroded.
Condensate shall not discharge into a street alley or other areas so as to cause a nuisance.
Copper glavanized steel cpvc and pex or pe rt are all approved.
11 pipe should be of approved materials.
System application and material usage.
An auxiliary drain pan with separate drain.
M 314 2 2 drain pipe materials and sizes.
Pvc is not approved because it is not rated for transporting hot water.
For condensate drain applications solid walled pipe either schedule 40 or constant pressure rated standard dimensional ration sdr is used.
I don t have an outside drain for my condensate pipe.
The recommended material to use for a condensate system is stainless steel.
These drain lines carry away condensation produced by the operation of the evaporator on the air conditioner unit.
An auxiliary condensate drain pan at least 1 5 deep and at least 3 larger than the length width of the appliance beneath which it is placed using corrosion resistant material of adequate thickness 0 7mm galvanized metal or 1 6mm non metallic e g.
Pvc piping systems are recognized as acceptable for use in condensate drain systems in all major model plumbing codes.
If amines commonly cyclohexylamine morpholine or diethylethanolamine deae are fed properly to neutralize condensate pipe ph condensate pipes can last.
Stainless steel greatly enhances the pipes ability to withstand the corrosive attack for a longer more reliable.
