My AC man in Sarasota used to put his shopvac on the outside pipe and vacuum it out in about 5 seconds. Allan.

Re: the POA newsletter, vinegar is acidic and will corrode the copper pipes. I use "AC LINE." This looks to be a soapy solution. Get it at Home Depot.

I have a Trane system and my AC guy said use warm water . I flush it out once a month when I clean my filter

[The Great Fumar]

Just use Hot Water!!!!! If you do it monthly, you won't get build up. NO BLEACH!!!!!!!!!!!

[dsettl]

Use Bleach full strength, 1/2 Quart Do it every two months

Clerk at Ace Hardware suggests running a hose from hot water tank to AC drain. Flush out monthly. Run water for a few minutes each time. Cleans sediment from tank and clears drain lines.

Vinegar can't hurt anything. You could pour a gallon undiluted thru there and it wouldn't hurt. Same with your garbage disposal.

Thanks for the tip, rhredd! I might give that a try next time I want to flush the A/C line.

Make sure you let the sediment, etc. drain out of the hot water tank first (into a bucket, out into the driveway, etc.) before introducing the stream of water to the A/C condensation line, though. That'll keep the tank crud out of the condensation line.

The issue here seems to be is bleach safe to use.

Obviously hot water is fine it is used through out the house draining thru your PVC pipes, I did a search (after Bill explain how the system works offline, tks)

It is fine as per;
While PVC is incompatible with many organic solvents, it has good corrosion resistance and is compatible with most common mineral acids and bases. You already know, for example, that pouring drain opener down your drain does not damage your PVC pipe, and drain opener contains sodium hydroxide a stronger base than the sodium hypochlorite in your bleach. Unlike sodium hydroxide, sodium hypochlorite is also an oxidizing agent, but PVC is nonetheless resistant to sodium hypochlorite as well.

Compatibility

PVC has excellent chemical compatibility with common household bleach brands, such as Chlorox. It is resistant to solutions of potassium, sodium and calcium hypochlorite, all of which are used in various types of bleach

[QUOTE=TommyT;368778]Help.... for the life of me I cannot remember what I'm suppose to pour into the Air Conditioner drain once a year to keep it flushed out. I've done a search and saw many, many posts about Bleach and other things, but I'm looking for a tried and true measure.

What do you use and at what mixture ????

TIA

Contact the company that made the unit. They would have the correct answer.
