Sounds like you have unequal water pressures. Fit a pressure reducing valve to the higher pressure side.
Why does my basin waste leak?
It needs silicone between the flange & basin (it will appear as if it is the plug that can’t hold water but the water is seeping under the flange and into the slots on the waste underneath).
Why isn’t water coming through the douche on my 3-hole bidet?
You need to remove the perforated plate and wind up the slotted screw (wind down to reduce water flow).
My mixer tap is leaking
Remove the head (by removing the “indice cap” or loosening a grub screw) then clean the seating and the rubber washers or ceramic disk valve.
Water trickles from the tap after turning it off
This is caused by ‘capillary action’ and residual water in the spout is being siphoned out. It should only last for a second or two, and is a nuisance rather than a fault. If the tap is fitted with an aerator, this can be replaced with a more restrictive type to reduce the amount of water that trickles out.
Why does water come up through the pop up rod hole on a three hole mixer?
Sounds like the packing nut on the spout is loose (second nut up from the bottom). Tighten it up and the problem should be solved.
I’ve installed an electric shower and the low pressure light won’t turn off
If the water gets warm, then the water supply pressure is only just sufficient to operate the shower. The low pressure light may not show at different times of the day, as the mains water pressure varies. If it doesn’t get warm then there is insufficient water pressure. Check the mains water pressure which must be a minimum of 1 Bar, and check the filter in the joint between the solenoid valve and the inlet connection elbow as it may be partially blocked.
I’ve fitted a shower pump but the shower pressure is unchanged
Check that the pump is installed correctly. If there is air in the pump due to incorrect installation, or if the water is too hot, it will reduce the amount of water that the pump can circulate.
The shower pump is making a lot of noise
Check that the location of the pump and the water supply connections are as shown in the installation book. The pump should be at the base of the hot water cylinder and hot water should be taken from the domestic hot water supply pipe below the vent tee or an ‘Essex flange’ in the side of the cylinder.
The shower pump won’t start
Make sure that the electricity is turned on and the fuse is ok. Check that water is flowing from the shower head when the shower mixer valve is turned on. If not, lower the shower head into the shower tray or bath and check again. If the pump starts, turn off the mixer and try again with the shower head back on the rail. If it still doesn’t start, it may be necessary to fit a negative head switch.
I’ve fitted a bar shower and the water isn’t getting hot enough
Check water supply pressures. Thermostatic valves require reasonably balanced water pressures i.e. not gravity hot and mains cold.
I’ve fitted a power shower and can’t get the pump to turn on. I’ve checked water flows from the shower head
Check that the purge switch (inside the cabinet) is set to “shower” position, or that ‘Eco’ button (if fitted) is not switched on.
The temperature of the shower is fluctuating. What should I do to make it constant?
Check that the hot and cold water supply pressures are reasonably balanced. Check that the combi boiler (if used) is not cutting in and out and if so, adjust the boiler temperature either up or down slightly.
Water is coming from the cold water tank overflow pipe, and there is warm water in the tank
Hot water is flowing from the shower, up the cold water pipe and into the tank. Check the non-return valves on the shower, or fit an in-line non-return valve in the cold water shower supply pipe to stop the problem.
I’ve fitted a new thermostatic valve and it gives only cold or hot water, but does not mix
Check that the supplies are connected correctly. The hot supply should be on the left hand side and cold on the right.
