I have a Zurn 375XL vacuum break back flow prevention valve on my house inlet water line. After a couple of years the diaphragm will tear and cause a water leak. This kit has all the necessary parts to repair and/or rebuild the valve. Between myself and the neighbors, we have repaired at least a dozen valves using this kit. Selection at Supply House is great, prices are very good and the service is quick and easy.
