Blue Viega Manabloc Valve Stem (Bag of 3)

These were purchased to replace several old style valve stems that had either broken or were frozen in place after not being rotated for almost 20 years. They were a perfect fit and easy to install. Highly recommended.

Will buy more…

Easy to use.

They were very easy to install. Only took minutes.

Replaced inferno part with newer and hopefully better parts.

I have a 20 year old manabloc system with original valves. Very problematic if ever tried to turn off water!! Ordered these beefier ones, work great!

I had a minor problem, and did not know who to call. Talked to Supply House and got educated and purchased the needed parts.

Switching out the old ManaBloc valves that had small diamond heads that broke or leaked to the Viega valve stems was the best thing I ever did. I purchased 32 Viega valves stems and replaced them all. Now I have confidence in turning on and off valves from the main ManaBloc manifold. Due to the prior cheap PEX Line install of track homes that didn't come with shutoff valves at the end of every PEX run, I also purchased the Sharkbite Push-On adapters and added valves to every bathroom sink and toilets, kitchen sink and dishwasher. Sure it's a bit pricer but makes the job much easier.

Replaced all my leaking shut off valves in 2 hours. So easy to replace I went and replaced all of them instead of the 3 leaking ones.

The product worked great. I used the tool to pull the old ones out and then put the new ones right in worked perfectly.
