Non Return Valve from Recessed Valves (Crosswater Z0A363N)
SUMMARY
Non Return Valve from Recessed Valves (Crosswater Z0A363N)
A non-return valve Crosswater Z0A363N is a one-way water control component used within selected Crosswater recessed thermostatic shower valves. It helps prevent water flowing backwards through the shower valve's supply connections and reduces the risk of unwanted crossflow between the hot and cold water supplies.
This non-return valve is supplied individually and is associated with Crosswater recessed valve assemblies manufactured across several ranges. It is important to identify the exact valve model and generation before ordering, as earlier versions may use a different non-return valve.

Symptoms and Checks Before Ordering
A faulty non-return valve may allow unwanted movement of water between the hot and cold supplies. Possible symptoms include crossflow, unexpected changes in water supply behaviour or inconsistent shower temperatures. Similar problems can also result from faults elsewhere in the shower valve, so the non-return valve should be inspected before replacement.
Check the exact model and age of your shower valve, and compare the existing component with the required spare. The older IBNRV and other Crosswater non-return valve references should not be assumed to be interchangeable with Z0A363N. The 22mm fitting reference alone is not sufficient to establish fitment.
Isolate the water supplies before removing or servicing the shower valve, and follow the manufacturer's instructions for the particular assembly.
