Once in a while, I have need to clear a clogged drain line
from an AC unit. Now, is one of those times. I've got a

ton and five eaches 8 ton AC. The drain line is about an
inch or 1 1/4 inch copper, with a vertical open top tube to
pour in some cleaner, or insert a blow gun tip. The drain
which is clogged is about 10 feet long, with maybe 3 elbows
invovled. Drains onto a rolled black rubber roof, so I'm not
eager to use chemicals.

Compressor and blow gun tip comes to mind. What other

carbon dioxide cylinder. Wonder if that's big enough.

Back in the good old days, we'd use a tank of freon to blow

buy these anti-biologic pellets to drop in the condensate pan (they last for

If you can get a garden hose up there, use a drain king. It's a

When you turn on the water, it first expands to seal against the sides

I have a couple of interesting gadgets that Johnstone used
to carry. The things are machined aluminum holders for the
small CO2 cartridges and have a 3/4" male pipe thread on
one end with a pair of small holes. You insert a CO2 cartridge,
screw the adapter on to the pipe, then twist the holder tight
which punctures the gas cartridge. It works fairly well for
some clogs.

Not really necessary; the algae clog is VERY slight - more like a spider web
in strength. If you can wrap your lips around the pipe, you can blow it
loose (don't suck).

I have two suggestions.

First you can use a snake.

The second option is to disassemble the line and clean each piece. It is a
ten foot run so this would mean one or two repair couplings to put the
sucker back together and that way you could clean the sucker out with a
broom stick.

I saw that drain blower, from Johnstone. The cartridges are
about two bucks each. But, it's a lot lighter than an air
compressor. I could much more easily carry it up the ladder,
also.

My plan at the moment is to use small compressor, length of
air hose, and a blow gun. Stick the blow gun into the clean
out, wrap with a towel, and squeeze the handle. Some of the
air will of course blow into the pan. But, much should blow
down the length of the drain. The drain is huge.

I'm wondering if wasps have nested in the open end. Need a
big nylon sock or something to keep the wasps out.

1) I don't have permission to replace the drain

I suspect the water does a much better job. Actually, the
three which are not garden hose accessable, they run just
fine. I may just carry up a funnel and some bleach and hot

I considered a sink drain snake. But, the access opening is
about 7 feet of the floor. I'd have to rope up a step
ladder, and not sure I've got enough space to open up a
ladder. I'm going to be standing on a stepstool reaching

I have a number of 20lb CO2 tanks that were meant for

can often be found abandoned in closed restaurants.
I've found several in dumpsters and set them up for

the HVAC supply house and use the CO2 to run air tools,
inflate tires and clear clogged pipes and coils.

If I end up blowing more drains at work, I may very well do
that. It's an excellent idea. Is it a bit heavy to haul up a

I've seen a fire department use a SCBA tank with regulator
to run an air chisel, for car extrication. Much the same,
I'd guess, for you. Don't want to get suffocated by the
tool's exhaust. Inflating tires would work fine. Most
liquified gasses work fine for tires. Propane is too
flammable, but there are some non flammable halocarbons that
work nicely. In emergency, you can also invert a halocarbon
tank to feed liquid, and reseat a tire on a rim.

To prevent over-snaking, measure the length of the pipe, then measure the
length of the snake and mark the snake to the max distance.

As far as wasps go, a rag stuffed in the pipe would probably prevent them
from exiting in your direction.

Nah. You'll smell the bleach for only an hour or two.

The AC only runs a day or two during the week. Plenty of
time for the nest to build.

Not with a constant trickle of water. Unless they're

Why run your tools on CO2? What is the advantage over just
filling from your compressor, or the local gas station?

The 20lb cylinder is filled with liquid CO2 which flashes
into gas when the pressure is let off of it. It boils at
-70 deg F and the 20lbs of liquid CO2 will produce a lot
of gas. Think of it this way, your car runs on the fumes
or vapor of gasoline so why not have a tank of vapor? It
wouldn't last very long would it? One pound of liquid CO2
will produce 8.741 cubic feet of gas.

Bleach works, they also have some tablets you can put in your pan that
keeps the crud from growing. We have a couple of HVAC units at work
that never get clogged. I have often wondered if it is because of the
copper drain lines, everything else is PVC.

Probably. Copper is a natural biocide (fungicide? herbicide? algaecide?
cantdecide?)

Hmm-- Never thought of that. I get along fine with my 10gallon air
tank, but . . . .

One pound of liquid CO2
will produce 8.741 cubic feet of gas.

If we can go direct from a gallon of 'air' to a gallon of CO2- then
your 20lb tank makes about
20*8.741= 174.82cu ft
174.82*7.48=1307gallons. . . Is that right?

What is the maximum pressure you can get for your air tools?

Will it run high volume using tools like sand blasters or rotary
cutters?

Thanks
Jim

Gotaride? You can come and help intheside.

A 20# cylinder will produce about 174 cu.ft. of gas. A sander can use 15
cfm, so you can run it for less than 9 minutes. Not a great idea, IMO.

Not unless you have some sort of heat exchanger. A lot of trim
carpenters use them for air powered brad or stapling guns. I
use it with my pneumatic pop rivet tool and air ratchet. The
problem with higher volume is that the line and regulator get
very cold and icy unless designed for the job. One day I'll
come up with a gadget that will flash high volume cold CO2
into nice warm high pressure gas.
