WC filling mechanism PLASTBRNO ONBP151 3/8 + 1/2 side

PLASTBRNO ONBP151 is a WC filling mechanism with side water connections in sizes 3/8" and 1/2". It features a universal connector and an integrated coarse dirt strainer to protect the valve from debris. The side inlet design allows installation in cisterns where water entry from the side is required, and the unit is suitable for replacement or new installations in compatible toilet cisterns.

Advantages

The mechanism provides dual-size compatibility (3/8" and 1/2") through included adapters, reducing the need for additional fittings. The built-in coarse strainer prevents larger particles from entering the valve, increasing reliability and reducing maintenance. Side inlet construction offers flexible installation options in different cistern layouts.

Suitable for

• Replacement of worn or leaking toilet cistern filling valves
• New installations in residential and commercial toilet cisterns with side water entry
• Situations requiring adapter compatibility with both 3/8" and 1/2" connections

How to use

Ensure the side inlet aligns with the cistern opening, secure the unit according to the cistern manufacturer’s instructions, reconnect the water supply, and check for leaks and proper fill level.

Usage recommendations

Regularly inspect the integrated strainer and clean it if sediment or debris is visible to maintain reliable operation. Use only compatible adapters and tighten connections to manufacturer torque recommendations to avoid leaks.
