WC Pans for New Bathrooms

WC pans terminate with a water-trap bend, known either as a ‘P’ or as an ‘S’ bend. The ‘P’ trap is used to provide an outlet through a wall, while the ‘S’ trap generally provides a floor outlet.

Some types of pan are supplied with a choice of ‘P’ or ‘S’ trap, have provision for outlet connection on either side of the pan, and do not need any extra connecting pieces.

A damaged and leaking WC pan should never be patched up, since the leakage could provide a serious threat to health and hygiene.

Where an ‘S’ bend pan connects to a vitreous, glazed pipe, take care to avoid damaging this outlet if the pan is removed. It is safer to break out an old pan at the bend, to avoid undue stress on the collar of the soil pipe.

Place rag into the collar to prevent debris from falling in when the pan is removed, and then carefully chip away the segments of the pan at the collar joint.

Such joints are usually consolidated and sealed with tarred hemp, called gaskin, which is wrapped together between the socket and spiggot. The joint may be finished with a mortar fillet, usually consisting of fast-setting cement.

When the joint for the new pan is to be made in a similar fashion, wrap the tarred hemp tightly round the pipe and push this well home. Do not allow loose ends to intrude into the pipe as this may cause blockages.

Where a type of suite brings the position of the pan forward of the one replaced, extension pieces, either in plastic, vitreous, glazed pipe or china, can be mortared in or, in the case of plastic, connected with rubber sealing rings. Modern plastic, push-fit rubber connectors are simple to fit and have the advantage of being easy to remove and put back.

There are various types of plastic connector which enable quick-fit connections to be made between the pan outlet and the soil-pipe. These have a screw-in stem and a rubber outlet seal and provide flexibility in movement, as well as facilitating removal of pans, without the tedious need to break out mortar collars.

When fitting a WC pan or bidet on solid floors, bed these on to a thick screed of mortar. First check that the pan is level and allow the mortar to dry before checking and testing for firmness.

Alignment of a new pan can be made using a spirit level. On uneven solid floors, small timber wedges can be slid beneath the pan to level it.

Never screw directly into the fixing holes through the WC base or you may crack it. Use brass fixing screws, set into rubber grommets. Brass will not corrode or rust. Tighten the screws down evenly but avoid overtightening.

Check that the pan is firm and free from movement. It must never rock, or joints might crack and the pan become unseated.

The only tools needed to change a toilet seat are a spanner and a screwdriver. There are three basic types of fixing, all through pre-made holes in the back of the pan. Differences are only of detail and instructions should be supplied with a replacement seat.
