Traps (plumbing)

Below are some examples of things known as ‘Traps’. They are found at various locations around the home and come in lots of shapes:

Bottle.

These traps are very dependable generally, being neat and tidy. They can be quite easy to block and have a width that is restrictive and therefore cant really allow fitting in pedestals. A purchase of a mini bottle trap can sort this issue. Traps with an adjustable height also exist which helps if the waste discharges out of a wall. Kentish Town Plumbers use all types of traps daily.

P.

This type is more flexible in that it can be adjusted. They often come with a height adjustment facility, great if your fitting a new basin into an old point and are have trouble aligning the waste pipe work.

Straight-through.

A great design for a trap, as the waste will run down a purpose made path cut into the body of the trap. However this causes access issues.

S.
A very popular trap, widely used and the favourite type if the pipes are coming up from the floor below. It can be very easily altered to fit pipework. A Kentish Town Plumber fits this and all other types of trap.

Self-Sealer.

This type of trap is is very much the same as the S-trap in terms of pros and cons for its use, also on the plus side they do not lose their seal. A great trick, fitted to a basin that is going to stand idle for a long period of time. This trap can be hand tightened, although a quick ¾ turn using a pair of pump type pliers will make remove any doubt.

Do not start tightening with pliers as the plastic thread of the trap can be very easily ruined by the brass thread on the waste.
