Soil Pipe Woes....

[Andy-D]

Hi,

Changing out an old WC and have some problems with the new WC and the soil
pipe.

The existing soil pipe and WC is in the corner of the bathroom. The soil
pipe exits through a solid wall and is about 6" away from the rear wall
(pipe runs parallel to rear wall).

My problem is that the new WC has to go fairly tight to the rear wall and
the height of the soil pipe is higher than the outlet on the new WC. The old
WC has a small concrete plinth

so perhaps the height has always been wrong and the pipe was originally
installed incorrectly.

I have thought about using a Swan Neck connector to get the new pan closer
to the wall, but I'm a bit stumped about the height problem???

It would be a bit of a nightmare to lower the soil pipe to fit the WC,
building another plinth may be tacky, a new WC would be costly.......

Any ideas, any help would be greatly appreciated.

Andy

You could use an offset pan connector, but these are intended to solve the opposite problem, i.e. where the soil pipe is lower than the pan spigot.

In short, you're a bit b*uggered. The best solution, in terms of the plumbing (i.e. in the interests of a good flush and a trouble free life of the system), is to put the pan on a plinth. This assumes that you have a standard pan, with the centre of the spigot at about 7.5" from floor level - if not then you might benefit from a change in pan.
