FAQs

This is not uncommon for products which do not have an aerator supplied, and some products with specific spout designs. This would be due to a syphon effect, which is created by changes to atmospheric pressures / heat changes within the product; this is quite normal.

Not all products are suitable for all installations. Our website & brochure details the pressure required to enable a tap to function to its optimum performance. If the pressure supplying the tap is suitable for the product; check the flexible tails for any potential blockage. Perform maintenance to the cartridge, to remove any potential blockage.

Whilst the majority of Crosswater products are compatible with most systems, some high pressure (HP) products are designed to work with high pressure systems only. Products marked LP (low pressure) and MP (medium pressure) are also suitable for high pressure systems. LP Minimum 0.2 bar
MP Minimum 0.5 bar
HP1 Minimum 1 bar
HP2 Minimum 2 bar
HP3 Minimum 3 bar
HP4 Minimum 4 bar

Generally, when a lever becomes stiff or difficult to operate, this would usually indicate a build-up of scale / debris within the ceramic disc cartridge, which is located beneath the operating lever. By performing regular maintenance on your cartridge, this can easily resolve this issue. Details on how to remove the cartridge can be found within the installation / maintenance instructions of your product. Once removed, soak in a descaling solution (or a 50 / 50 mix of warm water and vinegar) for approximately 2 hours, flush under cold running water and replace. Regular maintenance is particularly important if you live in a hard-water area.

All of our brassware products should only be cleaned with warm soapy water and a soft cloth. We would not recommend the use of any proprietary bathroom cleaner, as some contain harsh chemicals which may cause irreversible damage to the chrome plating.

Fitting Instructions / Dimensional Drawings / Exploded views can be obtained from the specific product page within the Crosswater Website.

Due to the majority of the UK being built upon chalk, unfortunately Limescale is a common issue. When Limescale builds up around the nozzles of a shower-head, this can create blockages / mis-direction of water flow. To remove the limescale, and restore your showerhead to full functionality once more, soak a cloth in a 50/50 mix of warm water and vinegar, and gently clean the limescale from the nozzles of the showerhead. Once removed, clean all over with warm soapy water and a soft cloth.

Your thermostatic valve can be delivering either hot or cold water for various factors; you should look at the length of time the thermostatic valve has been installed to take the necessary actions. Please note all Crosswater thermostatic cartridges fail to cold only, if your thermostatic cartridge is delivering any temperature other than cold it proves this is not the cause of the fault. 

The thermostatic valve has just been installed: If your thermostatic valve has just been installed this will typically point to the hot and cold supplies being installed in the incorrect inlets. The cold and hot will need to be re plumbed to the correct outlets for this to be rectified, if you have a Crossbox valve you can swap the two non-return valves over to rectify this. 

1 month +: if your thermostatic valve has been installed for longer than 1 month and it is delivering hot or cold water with no intermediate mix this could point to a build of limescale and debris on the filters for the Non return valves and/or the thermostatic cartridge. This builds up can inhibit the flow of water and therefore the mixing of the water.

All of our shower valves are mixed water blending valves; therefore they need to be installed with balanced pressures. If your cold water is being supplied from mains water, and your hot water supplied via a combi boiler, you could have an imbalance of pressures which exceeds 0.5bar. If this is the case, a Pressure Reducing Valve would need to be fitted to the cold water feed to the shower valve, and the pressure reduced in line with that being supplied by the combi boiler.

If pressures are balanced, the following maintenance routine should be adopted: By following the maintenance instructions within the product installation instruction guide, provided with your shower valve; isolate the water supply to the shower
valve and remove the following:

Thermostatic Cartridge
Non Return Valves

Once removed, soak in a descaling solution (or a 50 / 50 mix of warm water and vinegar) for approximately 2 hours, flush under cold running water and replace. Regular maintenance is particularly important if you live in a hard-water area. The thermostatic cartridge should be re-calibrated, in accordance with the instructions supplied with the product; to provide you with the desired temperature.

All of our brassware products should only be cleaned with warm soapy water and a soft cloth. We would not recommend the use of any proprietary bathroom cleaner, as some contain harsh chemicals which may cause irreversible damage to the finish of your product.
