AMMRL: How to make a flood

Hi all,

Reading Josh's remarks about his flood
reminds me of ours. It is a short tale of what
NOT to do with airconditioner condensate.

Our 400 is not in a pit but it is one floor above
ground level in a five story building. A drain
pipe runs down from the gutters (above the 5th
floor) to a drain on the ground. When our
aircon was installed the engineers ran the
condensate line into the drainpipe AT OUR
LEVEL and sealed it in place.

All was well for about 12 years. Then two
events occurred simultaneously:

1. The drainpipe blocked below our
condensate pipe's connection.
2. We experienced a massive thunderstorm
with torrential rain.

The result was that the drain pipe filled very
rapidly and the significant 'head' of water found
the only remaining outlet by flowing back
through our 'split' aircon's wall-mounted
evaporator and onto the control desk.

Fortunately I was working late when this
occurred. The first I knew was when icy water
at several litres per second started cascading
over the PC, monitor, printer and I. I remember
taking off my tee-shirt to protect the monitor.

Eventually we found the cause and ripped the
condensate pipe out of the drain pipe. It now
has its own discharge path independent of the
drainpipe.

A cautionary tale. Please have a look at your
aircon condensate pipe's discharge
arrangements.

Sincerely,
Andy||---------------------------------------------
