Ellen Cheesman is fully qualified for installation and testing of RPZ valves.

All areas of the country are covered, prices vary according to location and quantity on each site.  For a personal quotation please call and speak to us.

Testing is normally carried out Monday-Friday between 8.30 and 4.30pm, although out of hours testing can be arranged.

A copy of our terms and conditions for testing can be sent on request.

Our test equipment is annually maintained and we are recommended by manufacturers and water companies.

All customers receive a personal one to one service from first contact to test or installation to guarantee a high quality service.

These valves are required to be tested annually and we run a reminder service to avoid problems with out of date tests.
