What's Included
- 5x Talbot MDPE double check valve - E3783
This Talbot double check valve prevents a backflow of unwanted/contaminated water from re-entering the supply network. Finished in durable black polyethylene and WRAS approved, this compact valve combines reliable backflow protection with robust performance for domestic and commercial plumbing applications.
Simplified Installation
This valve features a straightforward push‑fit connection for a 20 mm MDPE pipe, making installation quick and simple without the need for nuts or threaded fittings — just push the pipe into place for a secure fit. As pressure and tensile load increase, the grip and seal on the pipe strengthen, helping to maintain pipe integrity under stress.
