Over-rim supply bidets are really only low-level wash basins and they’re plumbed in precisely the same way. Typically, this means taking branch pipes in the pipes that supply the other parts of bathroom equipment. If the pipes are 22mm, use 22mm to 15mm reducing tees to create the branch. Before starting work turn off the water and drain the system as required.
Twist the bidet to the ground using brass screws special ones which take a covering cap that hides the screw can be purchased. Use washers and tighten gently to make sure the bidet isn’t cracked. If a basin mixer is used rather than separate taps, then both hot and cold supplies must come from the cold water cistern, or a divided-flow mixer must be used.
Particular mixer taps (usually one-hole) are created for bidets in which the outlet nozzle is adjustable. A number of these can be fitted with a pop-up waste.
The waste outlet from a bidet is composed in precisely the same manner as for a clean basin – use a slotted waste sealed with pipes adhesive with a snare connected to it. In a two-pipe waste system, it may be fed into a hopper head instead of attached to the WCs soil pile.
For bidets with ascending sprays (which can include almost all through-rim types), the plumbing requirements are somewhat more complex. This sort of bidet cannot be linked where the cold supply in the home is direct – and even in an indirect system, it ought to be fed by its own separate pipe from the cold water cistern that feeds nothing else, except possibly a WC cistern.
Another method of linking an ascending-spray bidet would be to select the link from the cold water cistern and hot water heater at the standard manner but to take them to another cistern or into a ‘tun-dish’ where they are blended prior to visiting the bidet.
It’s quite beneficial to have a tap out -to which a hosepipe can be attached or that could be utilized for filling watering cans. So as to provide the type of pressure required for a hosepipe, this faucet will most likely need to be linked to the rising main that, under the new water by-laws, will mean fitting a double check valve at the branch pipe in addition to a stoppage – the check valve is fitted between the stop valve and the faucet. Installing an outside faucet is just another job where you must inform the regional water supply undertaking.
