The manifolds arrived quickly and were well packaged. I compared these to some of the more expensive manifolds on the market and I have to say I made the right choice. The fit/finish is very good and overall I feel a great value. Let's face it once setup your going to forget about it. I have already installed them in a on slab concrete floor and they are working very well.

I see that you do not recommend installing the manifolds up side down. What about installing the manifold oriented vertically with the tubes entering the manifold horizontally? Will that be satisfactory?

The issue with upside-down and vertical installations is that the flow meters can get clogged and stop working over time, which in turn, would restrict the flow of water through the branch. If a heating system contains non-ferrous parts only (i.e. copper, brass, PEX), it should not be an issue. If, however, the system has cast iron components, they are likely to cause the above mentioned scenario. As a solution, you may have to use a magnetic dirt trap, but for the cost, it may be better to install manifold horizontally and use bend supports to route the PEX up.

Can this manifold be turned upside down? My 1/2" PEX tubing comes from the ceiling and not the bottom as shown.

We do not recommend installing the manifold upside down since it will hinder the operation of flow meters and will lead to their early failure and need for replacement. Instead, if possible, install the manifold in a regular manner and route the PEX tubing to the sides and then up. You can use bend supports to assist in a 90-degree transition.
