AC Condensor drain

[95DRGT]

My unit is in the attic and I have a backed up drain. The drain runs about 40 feet and feeds into a kids bathroom. Due to all the joints and right angles ( and small diameter PVC) it frequently gets clogged. I try to flush it a couple of times a year with white vinegar to clear out all the gunk. I tired of doing that and want to improve the system or an easy way to clean it out.

Question- Is it code for it to drain into the sewer system (bathroom sink plumbing?

The overflow pan drain drains out to the side of the house so I don't get why this one was plumbed into the sink.

Pic of plumbing I want to replace- p trap removed so I can attempt to try and clean

From my very low level understanding draining into the secondary bath is normal, I have seen it a couple of times and that is how it is in my house. Don't know for sure about "code" though.

The one that goes outside the house is a "secondary" drain, in the event your primary clogs up. Some bleach on a regular basis should help, but it looks like you have too many T's in there instead of 90's. Also try a little compressed air.

I feel your pain. Ours is plumbed exactly like yours. I had a full blockage last summer and spent 3 hours forcing a snake up the wall from the under the bathroom sink. It was packed solid somewhere in the horizontal section between the unit and the wall down pipe. That was the first time I've had to do that with this house so the clog had been forming for over 6 years and from the sediment that came out, I believe it.

There was a shitty dishwasher drain type hose with pinch clamps that wasn't adapted very well coming from the wall to the p-trap. I replaced it with 1" heater hose from the wall and then used a heater hose reducer and more heater hose to adapt it to the trap, all bundled up with worm gear clamps.

This reminds me, time to flush that bitch out again.

Bleach, wait 10 minutes then flush with HOT water.

Jesus Christ that's some shitty looking plumbing!! I'm not a plumber, but god damn....it's not rocket science. It doesn't take much intelligence to know that's a pisspoor way to route some pipe!

Must've been charging by the foot and by the fitting...

Yea I ended up cutting all that crap out today and reducing the number of fittings. I made it all removable so I can detach then hook up a shop vac to the pipe coming from the wall. I used the shop vac today to suck all the remaining crap from the system today. My little 1 gal shop vac hose fit over the 3/4" pipe perfectly and cleaned out a good gallon of crap/sludge out.

That is normal, they clog all the time. We typically use nitrogen to push the gunk through. A shopvac works also

I rerouted everything and made it removable so I can shop vac it clean a few times a year

Yea o always make them accessable anytime I come to one that's not.

If the AC drain is plumbed into the sewer drain, you beter be sure that the P trap is alwys full of water. If the trap goes dry, you will get sewer gas back up the drain pipe into the AC system and it will go all over the house. Bad deal. As long as the trap under the sink is full of water, you have no problem.

Its in my daughters bathroom. She runs the sink at least once a day-seems like it would always be full even if if she was gone for a few days. The AC is draining there too so I can't see that it would ever be 'dry'

The one that goes outside the home is a "secondary" strain, in the occasion your main blocks up. Some lighten regularly should help, but it looks like you have too many T's in there instead of 1990's. Also try a little compacted air.

Will someone please ban this spamcunt?

I used pure bleach on ours and we had to evacuate the house for a few ours. Id did clean out the lines, though.
