Washington DC Furnace Guide: Condensate Drain Line Freezing Problems

Monday, October 22nd, 2012

As you know, the condensate produced as byproduct during normal operation of your Washington DC home’s furnace has to be drained away. It’s toxic, very acidic and has been contaminated by the normal combustion that takes place in your furnace, so you certainly don’t want it hanging around.

The typical solution is to have it drain out through a drain pipe, usually beneath the floor of your basement foundation, or down the side of your home and out through a downspout. But have you ever had your condensate line freeze up on you? That is no fun chore to deal with.

A frozen condensate line is usually caused by poor insulation. What happens is that when the temperature drops, the rate of drainage begins to slow down and the droplets begin to freeze one by one, like icicles, until the whole pipe is frozen. This creates obvious problems and can interfere with the proper heating of your home.

Usually, this just means the pipe is poorly insulated, which is a solution that can be remedied. If you have a condensate drain line that freezes anywhere other than under the foundation – for example, one the runs down the side of your home – you can try wrapping it in heat tape.

Sometimes, the best way to rectify the situation once and for all is to reroute the pipe. This can be a somewhat involved process, depending on where the drain line is. For example, if the pipe is poorly insulated because it is buried to shallow beneath the foundation, it will have to be dug up to be rerouted along a warmer path.

If you have already tried insulating the pipe with heat tape or some other solution, but the freezing problem continues to occur, then rerouting is probably your best option. For that kind of job, the average homeowner should consult with a Washington DC heating professional, as the job can get challenging and a little dangerous.
