Condensate Drain Line Installation Code

Can condensate drain lines connect directly to the sanitary sewer system or must there be an air gap or air break at the point of termination.

Condensate drain line installation code.

Imc 307 1 and cmc 310 1 talk about condensate from the cooling coils we re installing in people s homes. Let s take a look at what the codes say about condensate control and adherence to the code when doing an hvac change out. 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. Codes installation leaks clogs connections troubleshooting repair.

Does the ac condensate line have to be rigid pipe where it attaches to the tail pipe of a vanity. Ductless mini split equipment that produces condensate shall be provided with an inline check valve located in the drain line or a trap. This drain deserves an f. The applicable codes are the 12 imc ipc.

A c condensate drains pumps. Condensate drain lines serving more than one appliance shall be approved by the authority having jurisdiction prior to installation. No trap clean out no vent. I am looking for code sections regarding condensate drain lines.

This article discusses the inspection and repair or un clogging of condensate disposal systems including air conditioning heat pump or condensing boiler furnace condensate drains condensate pumps and their proper installation as part of our review of condensate piping traps drains. Trap failures due to freeze up drying out breakage blockage and or improper installation can compromise the seal against air ingestion through the condensate drain line. With no overflow safety switch no clean out and no vent one is just asking for several thousand dollars of damage due to condensate water backing up and overflowing the cooling coil drain pan flooding out this interior furnace closet. Use of rubber type hose to make the connection from the pvc condensation drain to the sanitary side of the sink tailpiece is common practice at least in this part of tx.

Traps with insufficient height between the inlet and outlet design deficiency on draw through systems can cause the drain to back up when the fan is on possibly causing drain pan overflow or water droplet carryover into. It can air lock because there is no vent after the trap.
