Review: Easy to Install - Product arrived as advertised with all parts included. I Installed Manabloc with the option to supply water using top inlets only. I needed to order the supply connectors for the supply inlet on top as instructed on Manabloc advertisement. I also needed to order the bottom supply cap as my example did not require this water inlet. My installation was a little tight due to where my PEX pipes were planned to go into the Attic and also staying at least 18" away from water heater as instruction indicated. First I placed the manabloc where I planned, Second I ran each of the hot and cold lines into the attic. Then I began to make the water supply connections into the Manabloc. I then made the multiple crimp connections to connect the attic supply PEX lines into the Manabloc. Once I completed all the Attic PEX line connections into the Manabloc I opened the water supply Cold and Hot lines into the Manabloc to test for leaks. I tested at this point for all connections made just into the Manabloc before doing any further work. I heard the Water filled Manabloc and confirmed that there were no leaks. While still in the garage area where the Manabloc was installed, I finally went through the connection of each of the Attic PEX lines into the Manbloc and then I finally spent the one full day in the Attic to make the 13 PEX connections to each of the copper lines going to each of the water fixtures. My plan was to cut off the copper existing lines before they go into the wall from the attic to fixture and solder crimp connections to allow me to crimp the PEX to each of the copper fixture lines. Once completed, I opened each of the water lines from the Manabloc one at a time and verified that there was no "water leaks" to the soldered/ Crimped connections. Complete installation took 3 days from start to finish. I would recommend this product. Very happy with final results.

This product is made of PEX material, not metal. And main inlet and outlet adapters are not included. Please add #50141 manabloc adapters and/or V5036.10 manabloc end cap to complete installation. **Q: Can one use a regular pex crimps?** A: Make sure you get the pex crimp version. This one has the pex tubing attach with Compression fittings that need a special wrench from Viega to be able to easily do them all. **Q: does this include the supply adaptors for the 14 ports?** A: Those are the outlets and it has more than enough. Just make sure you order the manibloc that has what you want. Some are 1/2 in pex crimps, some are others. Make sure you read the ad to see which one. You will need 2 supply adaptors and a cap or three supply adaptors and no cap depending on how you're using it. Those are separate **Q: can this manifold be installed in a crawl space?** A: I installed the one that I got in the crawl space under our cabin in an insulated box that we built for our hot water heater. During freezing temperatures when the water lines are not drained the manifold is kept warm by the residual heat given off by the water heater. if the manifold has water in it and the temps reach freezing, the manifold will probably break. Unlike pex plumbing, the manifold is not designed to freeze without breaking. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to Install *by J***. on February 1, 2021* Product arrived as advertised with all parts included.

Works well no leaks. Make sure u get this one it comes complete with fittings, others are 5 or 6 dollars less and dont have the connections necessary to complete the work.
