Cutting and Fitting to cast iron soil pipe

[smudger]

I've got to fit a new upstairs toilet for a customer. The existing has a cast iron soil pipe. This need to be shortened by approx 200mm. Is it best to use a grinder, I'm concerned about the amount of dust this will cause. Also, will standard plastic fitting get a good seal? I haven't worked on cast iron yet and woul dreally appreciate any advise.

Hmm!

Does make some mess I must agree. You need to watch out for the sparks as well they can easily burn things. Preferably a larger size grinder is probably best, one that can cut right through the pipe without having to move your position. And don't forget to keep your balance the thin cutting blades can sometimes shatter if you move to much. You also of course require goggles and gloves and so on.

Other than that its easy enough to do.

There are numerous Mc Alpine Multikwik's that would suite and make a good seal.

A good trick is to take an old magnet with you for getting all the small iron filings up, if you can't sweep or Hoover them up.

Good Fortune

Great tip about the magnet, luckily there's no carpet and I will be tiling before fitting new toilet. Thanks for the tip bernie, grinder it is.

Hi! Smudger,

The magnets off the back of old moving coil speakers are great for the job. Otherwise if you miss any filings, after a while they rust and you get all red stains all over the place.

Problem is, half the time you can't see the filings so you don't know whether you have picked them up or not and Hoovering them up could wreck the Hoover if they go through the filter.

Err! I know it can happen, by having been soft enough to do it and err! many times.

But hey! Isn't it by having made mistakes we sometimes learn?

Your right, but if I can learn from your mistakes, lol . Have to take the wife's hoover and not my nice wet n' dry!!
