The V3191-01 is a vertical adaptor assembly for Clack WS1 control valves, used where the installation requires pipework to enter and exit the valve from below rather than through the standard side-mounted inlet and outlet ports. It's commonly fitted on cabinet softeners and space-constrained installations where a vertical plumbing arrangement is needed. Supplied as a complete adaptor, it's a straightforward swap or addition for installers reworking pipework layouts. Stocked by WrekinWater as a genuine Clack spare.

Symptoms that mean you need this part
- Your installation needs pipework to enter the WS1 valve vertically rather than from the side
- The existing vertical adaptor is cracked, leaking or missing an o-ring seal
- You're fitting a cabinet softener or space-constrained install where standard side ports won't line up with your pipework
- You're reconfiguring an installation's plumbing layout and need to change the valve's connection orientation
Why it fails / why it matters
Most WS1 valves are plumbed with inlet and outlet connections entering from the side, but not every installation has room for that layout - cabinet softeners, under-sink installs and tight utility cupboards often need the pipework to run vertically instead. The V3191-01 adaptor assembly fits onto the WS1 valve body to redirect the connection orientation, sealed with an o-ring against the valve ports. As with any adaptor carrying full mains pressure, the housing or seal can crack or wear over time, and a weep at the adaptor face is the usual sign it needs replacing.

How to fit it
- Isolate the softener at the bypass valve and shut off the mains supply before disconnecting any pipework
- Remove the existing side-entry fittings or old vertical adaptor from the WS1 valve body
- Inspect the valve ports and o-ring seats for damage or debris before fitting the replacement
- Fit a new o-ring to the V3191-01 adaptor and lubricate lightly with silicone grease
- Fit the adaptor assembly onto the valve body in the correct orientation for your pipework layout and secure it
- Reconnect the pipework, restore the mains supply, and check every joint for leaks before returning the softener to service
