Top Ten Bathroom Plumbing Tips

There are an array of things to consider when plumbing in a new bathroom ranging from checking the pressure of the water to concealing pipework. Here we share our top ten bathroom plumbing tips.

Conceal the pipework

There’s nothing worse than unsightly pipework on display in your new bathroom. To ensure that pipework is hidden from view it’s essential that walls are chased out and floors are lifted to conceal the hot and cold plumbing as well as the waste pipes.

Choose flexible plumbing

Plastic fittings can be much easier to retro-fit; this is because a flexible pipe can be threaded through joists and around corners, removing the need for joints.

Check the water pressure

Before choosing a new tap or shower it’s essential to check the pressure on your hot and cold supply. Some taps and showers require a high pressure of 3 bar, which means that they won’t be suitable for use with a gravity fed systems.

Eliminate bad odours

If there’s a run of waste pipe that’s more than two metres in length, the displaced water can pull the air from a waste trap that’s close by instead of from a vent pipe. This siphons the water seal, creating a gurgling noise and releases drain smells. Fitting anti-siphon valves in the waste pipe helps to prevent this from happening.

Electric showers

If you have a combi boiler that is lacking in hot water flow or pressure, installing an electric shower provides the best solution for supplying hot water on demand.

Large shower heads

For those who have a powerful shower or a large shower head it’s recommended that you fit a 50mm waste pipe instead of a 40mm version. A 50mm waste pipe copes much better with a higher flow rate.

Low profile shower trays

For where there is not enough of a drop within the floor void for the shower waste, usually a common issue with low profile shower trays, raising the floor level to create a void offers the best solution. The waste pipe could be run between and below the joists and then boxed in at ceiling level in the room underneath.

Circulate the hot water

Hot water can take a while to arrive to the taps and shower if your bathroom is on the end of long run of plumbing. To solve this problem connect the end of the plumbing run back to the hot water cylinder and fit a bronze pump on the loop; this allows the hot water to circulate and the taps will then instantly deliver hot water when turned on.

Isolation valves

Isolation valves fitted to each pipe in the bathroom ensures they can be simply shut off if any maintenance work needs to be carried out. Individual and master shut off valves located behind a panel that can easily be removed offers a neat solution.

Fit a small bore waste pipe, pump and macerator

A new bathroom will ideally be connected to a 100mm soil pipe, but sometimes this isn’t always possible. Fitting a flexible small bore waste pipe as well as a pump with a macerator means that you can install your new bathroom anywhere you require.
