Chapter 9 Sanitation systems

● Bath waste and overflow kit: where there is sufficient space underneath the
bath, this is the easiest bath waste connection to fit. It uses a
one-piece bath waste connection, which is held in position by a long bolt
placed through the centre of the bath waste grille. Both the waste connector
and the grille have sealing washers. The bath waste connection incorporates
the overflow connection. The bolt pulls the waste connector and the bath
waste grille together, and this compresses the washers to make a watertight
seal.
● Bath pop-up waste and overflow fitting: bath pop-up waste systems are
becoming increasingly popular. They are fitted in the same way as a bath
waste and overflow kit, but feature a ‘twist action’ chrome or gold plate p Figure 9.47 The bath waste and
overflow, which operates a lever to raise or lower the bath waste plug. overflow fitting
● Combined waste and trap: this is a fitting that combines the bath waste and
overflow with the bath trap.

Whirlpool and air spa baths
The whirlpool and air spa bath is a recent addition to the bath range.

Whirlpool and air spa baths are considered luxury fittings and can take many
forms, such as jetted baths, hydro-pools, hydro-spa and air spa types, all of
which use the pumping of air and water through nozzles installed into the side
or floor of the bath. They can also be retro-fitted to any acrylic or pressed steel
bath. The pump is usually situated at one end of the bath. p Figure 9.48 The bath waste and
trap combination fitting

INDUSTRY TIP

The idea of the whirlpool bath to relax the body is not a new one. It was used by the Ancient
Romans. In the 1950s, the idea resurfaced when the Jacuzzi brothers developed the
whirlpool bath for domestic use.
