OK, finely got around to replacing V-coil drain cluster ___. I didn’t like all these fittings elbows was arranged creating drain restriction and unnecessary scum build up inside the cluster.


I found S drain trap tube that fit almost perfectly eliminating all the fitting cluster flow restrictions. You can see I used lock screws in case I need to disconnect in future?

Why the shut off. Not needed in the drain line...

So I can blow out drain with water hose attachment 55Psi pressure.

Nicely done!

Or pour a gallon of HOT water down the drain once a month...

I put some vinegar in the hot water. I always used to use bleach, but when I got to the villages they builder was adamant that bleach was bad and I should switch to vinegar. So it did.

There are no restrictions at the slow flow rate. You could have elbows all the way outdoors.

Since this is on the vacuum side of blower, doesnt this cause issues with dirty drain water backing up into the ventilation system?

I use this device to flush the drain. The rubber part expands and closes off the pipe, so there is no need for a valve.

According to Munn's, the Carrier Company no longer recommends using vinegar, only hot water.

My drain became clogged (bought an existing home which had been vacant) Munn's says the clog was due to biological buildup. Flushing with hot water was not useful to get rid of the clog. Quick research says that 5% vinegar (without dilution) is the only strength that is anti-bacterial, so now I use that first once a month, then use hot water to flush it out after about 5 minutes. As an aside, Munn cleared the clog out with a shop vac and sucked it clear from the outside. A shop vac is a very small purchase vs. the amount I got charged, so I bought one. The symptom was that the display on the Ecobee thermostat would disappear and then come back on and disappear, and of course the AC was not working long enough to cool the house adequately. The drain is PVC pipe, I don't see how 5% vinegar (or for that matter bleach) is going to hurt if you flush it out after 5-10 minutes.

My house was similar, previous owners didn’t nothing. I tried all the online tricks, but years of buildup wouldn’t disappear quickly. Water pressure blew it out in 1 minute.

My blow out attachments was free I had the parts. Nothing like 55 Psi, the cut valve prevents back pressure going up drain line.

When I remove the access port attach hose air handler blowing air blower blowing out my access port. Next time air handlers running I’ll go out side see if I fell any pressure?

Where are you getting the water from? Hose bib outside? Water heater drain? Other?
