Answer
You can build or buy a sewer jetter attachment for your pressure washer for less than $150. A sewer jetter is a thin, high-pressure hose with a jet nozzle that pulls the hose into the drain and breaks up the clog. With a sewer jetter you typically start from the main drain cleanout outside your home or in your basement, or from a drain opening such as an inlet under a sink that's upstream of the clog.

Using a power washer to unclog a roof drain?

We got our first storm of the season and I noticed today that the roof drain is slow draining/clogged. It's a flat roof that slopes into a 3" cast iron drain pipe. I put a snake down and it stops about 6 feet down where the pipe has a slight bend (maybe 60 degrees).

The pipe has a cleanout further down in the garage but these pipes are probably as old as the house (1926)and I'm pretty sure I wouldn't be able to get them off without hurting myself in the process.

So my question is - would it be wrong to try blasting water from my 1500psi power washer down the drain to see if I could clear the blockage? Any other ideas?



Answer
A sewer jetter is a machine designed to clean out pipes and lines, and it is really just a pressure washer with a pulsing valve and special hose/nozzles. You can even buy a jetter valve for your pressure washer to turn it into a sewer jetter. I will include a link in my sources to an article on hose size vs. pipe size. I also explained sewer jetter's in a recent Yahoo Answers question, so I'll link it as well. Bottom line, it is worth a shot, and if it doesn't work, you may be able to clear it out by getting some sewer jetter hose and nozzles that are designed for this kind of think.
