The 20014182 sealing ring is manufactured to original equipment specifications, ensuring precise sizing, correct material composition, and long-term resistance to heat, pressure, and chemical exposure from treated heating water.
The S1006400 3-Way Valve Cartridge is manufactured to exact OEM specifications, ensuring precise hydraulic fit, reliable movement, and long-lasting performance under varying pressure and temperature conditions. The valve cartridge is integral to the boiler’s ability to respond quickly to hot water and heating demands; if it becomes worn, sticky, or misaligned due to scale, sludge, or general wear, the boiler may deliver hot water when only heating is needed or vice versa, leading to user discomfort, inefficiency, and frequent fault codes. Because this component controls internal waterways, its smooth action is essential in maintaining system balance and preventing pressure fluctuations or flow restrictions.
Over time, continuous cycling between heating and hot water demands can cause internal seals and sliding surfaces in the cartridge to wear, leading to leaks between circuits, delayed switching, or partial heat delivery. Replacing a faulty valve cartridge with this OEM component restores accurate water routing and reduces unnecessary stress on pumps and sensors, improving overall boiler responsiveness and efficiency. Installation and calibration should be carried out by a qualified heating engineer, who will ensure the cartridge is seated and aligned correctly within the diverter assembly, preserving safe operation and compliance with boiler system standards.

If we can speed this up, we will, but you can also select Express Delivery when you check out and get your purchase more quickly (usually the next working day, subject to a 1pm cut-off): there is an extra charge for this ranging from £5 to £29.99 depending on the products you are buying.
We partner with several of the best UK carriers (such as TNT, Royal Mail, DPD etc) depending on the type of product and the warehouse it is coming from, and also with some pallet companies for larger items. All of these operate during normal Monday – Friday working hours, and we expect all deliveries to arrive in 5 days. For more details checkout this page.
For all Gledhill Cylinders, a flat delivery charge of £27.50 (ex-VAT) applies, regardless of order value or delivery method. This will be added automatically at checkout.
Having to return a product because it doesn’t fit, or is not what you wanted, is really annoying! To try and make sure this isn’t necessary we have lots of helpful advice on our site, and you should feel free to call our experts on the number above to check if you are in any doubt at all – we’re always happy to help.
But if you do, don’t worry, just contact us and we’ll get it sorted (note that for trade customers there may be a restocking fee). If you need it, we can usually arrange the carrier to pick it up.
