Nine times out of ten this is due to a build-up of debris/limescale on the valve/cartridge.

1. Isolate the water supply to the shower
2. Next step is to remove the cartridge/valve from the shower body as detailed in the step by step guide:
3. Once you have removed the cartridge it will need to be submerged in a 50/50 mix of white vinegar and water (preferably overnight). This will clean any debris/lime scale build-up.

We recommend that you clean your shower using a damp soft cloth only. Using any abrasive cleaning products is NOT recommended with our showers. Ensure you wipe/dry clean your shower after use to reduce the build-up of limescale and soap deposits.

1. Check the inlet feeds are fitted correctly with the hot being on the left and the cold on the right- this can be rectified by re-plumbing the pipework.
2. Mains feed cold supply is overpowering the gravity fed hot supply – this can be rectified by either fitting a pressure reducing valve on the cold or fitting a pump on the hot supply to boost the pressure. We also supply a brass orifice plate that can be fitted to the cold supply to reduce the pressure.
3. There may be a build-up of debris/ limescale on the valve/cartridge – this can be rectified by following the step by step guide. (INSERT LINK)
4. Once you have removed the cartridge it will need to be submerged in a 50/50 mix of white vinegar and water (preferably overnight). This will clean any debris/lime scale build-up.

*Please note all of our showers need a minimum of 60 degrees water temperature coming into the valve to ensure optimum performance

This will be down to atmospheric pressure in the bathroom which can be affected by something as simple as when the toilet is flushed or a window left open.

Residual water can be syphoned out by capillary action when the shower is turned off and shouldn’t last more than a few seconds.

Filters could be blocked on the inlets:

1. Remove the filters and clean any debris/blockages.

Possible airlock in the system:

1. Remove the shower head from the flexible/fixed kit
2. Start the shower in the coldest setting and slowly turn the dial to the hotter setting. If at any point the shower begins to splutter/spurt, then stop turning the dial and allow the air to clear before continuing to the hot.
3. You should repeat this process until all air is removed and then the flow from hot and cold should be the same.

The shower is not compatible with your water system:

1. Check your system pressure and check the product to ensure they are compatible.

Nine times out of ten this is due to a build-up of debris/ limescale on the cartridge/headwork:

1. Isolate the water supply to the tap.
2. Next step is to remove the cartridge/headwork from the tap body as detailed in the set by step guide below:

• Turn off your water supply and open the tap to drain any water from the system. Put the plug into the plug hole just in case you drop any small nuts/screws.
• Remove the tap handle/head – this will vary depending on which model tap you have. There will be a grub screw holding the handle/head together, this is usually covered with a cap which will need to be removed. Once you have removed the grub screw with an Allen key you will then be able to remove the handle/head.
• Unscrew the tap body shroud – usually, this is only hand tight however if you need to use a spanner/ tool to remove then please ensure you use a cloth to protect the chrome on the tap.
• Remove the cartridge/headwork – Using an adjustable spanner on the nut sitting below the tap spindle, turning the nut anti-clockwise will remove the valve/cartridge from the tap body.
• Cartridge/headwork to be submerged in a 50/50 mix of white vinegar and water (preferably overnight). This will clean any debris/limescale build-up.
• You will now need to reverse the process to return the valve/cartridge into the tap body and your tap should now be fully working again.
