Correct installation of condensate drain lines.
Condensate drain line installation code.
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.
814 5 point of discharge air conditioning condensate waste pipes shall connect indirectly except where permitted in section 814 6 to the drainage system through an air gap or air break to trapped and vented receptors dry wells leach pits or the tailpiece of.
Ductless mini split equipment that produces condensate shall be provided with an inline check valve located in the drain line or a trap.
The applicable codes are the 12 imc ipc.
A condensate drain hose should always include an inline waterless drain trap which is now mandated by the imc section m307 2 4 1 ductless mini split system traps.
Let s take a look at what the codes say about condensate control and adherence to the code when doing an hvac change out.
I am looking for code sections regarding condensate drain lines.
Does the ac condensate line have to be rigid pipe where it attaches to the tail pipe of a vanity.
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.
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.
Codes installation leaks clogs connections troubleshooting repair.
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.
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.
Imc 307 1 and cmc 310 1 talk about condensate from the cooling coils we re installing in people s homes.
Condensate drain lines serving more than one appliance shall be approved by the authority having jurisdiction prior to installation.
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.
This drain deserves an f.
