Frequently Asked Questions
How do I know if this cartridge fits my valve?
The DC70-T20 fits thermostatic valves using a 70mm diameter, 117mm length, 20-spline cartridge. Check your existing cartridge or your valve model against these specs. Compatible brands include Hudson Reed, Ultra Finishing, Crosswater, and Nuie — but always verify dimensions first.
What does "fully reversible" mean?
It means this cartridge will operate correctly even if your hot and cold water supplies are connected in reverse. This is a common installation issue and the DC70-T20 handles it by rotating the valve 180 degrees.
Does this work on low-pressure systems?
Yes — the DC70-T20 is rated for both low pressure (from 0.1 bar dynamic) and high pressure (up to 10 bar static) systems, with excellent flow rates at low pressure.
Can I order if the item shows as out of stock?
Yes — if the item shows as 0 stock, it is ordered in specially for you and will typically be dispatched within 4 working days.
Is delivery free?
Yes — free UK delivery is included.
Can I fit this myself?
Cartridge replacement is a straightforward job for a competent DIYer. Isolate the water supply, remove the valve handle, unscrew the retaining nut, swap the cartridge, and refit. If in doubt, we recommend using a qualified plumber.
I'm not sure which cartridge I need — can you help?
Of course. Contact us at customerservice@bubblegumbathrooms.co.uk or call 01603 381095 with your valve model or existing cartridge part number and we'll confirm compatibility before you order.
