Easy to install. The T handle/valve setup is sturdy. The 1/4 turn shutoff valves are great for faster hot water delivery. Need to buy the wrench separately.

Easy to install, with compression fittings and individual shut-offs. Re-plumbed my house in one day.

Replaced old polybutylene plumbing in my house. Instructions were easy to follow, and the installation was completed over a 3-day weekend.

I replaced an old Manabloc with a new one. Very easy to do it. Anyone can do it.

Replaced spaghetti runs of copper with this product. Easy DIY project with no need for a plumber. Water pressure even increased!

Couldn’t imagine installing the Manabloc without the wrench and the installation video. Super easy to install, highly recommended.
