NES Home Cold Start On/Off Replacement Cartridge - 35mm Flat Base

This cartridge is designed to fit most standard kitchen and bathroom basin mixer taps that use a 35mm flat-base cartridge.

Common signs include a persistent drip from the spout when the tap is turned off, a leak around the handle or base, or difficulty in operating the tap handle smoothly.

The product information does not specify suitability for high-pressure systems. It is designed for standard domestic water pressures.

A cold start function means that when the tap handle is moved to the central position, it only allows cold water to flow. You must intentionally move the handle to the left to activate the hot water, which can help save energy by preventing accidental heating of water.

While a plumber can install it, this cartridge is designed for easy DIY replacement. Basic DIY skills and adherence to the installation steps should suffice.

Ensure you have confirmed the 35mm flat base requirement before purchase. If it still does not fit, consult the retailer or manufacturer for return or exchange options.

The product information states a weight of 2.20462262 pounds. This likely refers to the shipping weight rather than the exact weight of the cartridge itself.

Ensure the new cartridge was seated correctly and the retaining nut/clip is secure. Check for any debris in the tap body that might be preventing a proper seal. Verify the cartridge is the correct size and type for your tap.

Check that the water supply valves are fully open. Inspect the tap's aerator (if applicable) for blockages and clean it. Ensure no debris was introduced during installation.

Ensure the cartridge is properly aligned and the retaining nut is not over-tightened. Check for any internal obstructions within the tap body.

Verify that the cartridge is installed in the correct orientation as per the manufacturer's instructions. Ensure no modifications have been made to the tap's original setup.
