## Overview

The GROHE Membrane 43733000 is a high-pressure diaphragm washer designed exclusively for GROHE inlet valves. Crafted from durable rubber and plastic, it ensures a tight seal to prevent leaks caused by wear or debris. With a threaded solvent connection and a compact design, it offers easy installation and reliable performance, backed by a 5-year manufacturer warranty.

## Description

Grohe inlet valve won't shut off properly it could very well be that the diaphragm washer inside of the valve needs to be replaced. Over time as the valve is continuously opening and closing, small tears can start to form in the diaphragm washer, in turn the diaphragm washer will no longer give a good seal and debris in the water supply can also contribute overtime to this washer being worn.
