In this video, we give a quick tutorial on how to replace the manifold flow meter of your underfloor heating system. Whether the flow meter on your UFH manifold is leaking or damaged, just follow these steps for easy installation.

The first thing you’ll want to do is make sure your underfloor heating system is turned off. Then, isolate the UFH manifold by turning off the isolation points on top and bottom.

Next, depressurise the manifold using the fill and vent ports. If you just remove the key from the fill and vent ports, you can connect a washing machine hose and discharge it into a bucket.

Once you’ve depressurised the manifold, all you have to do is lift off the cap and use a spanner to remove the manifold flow meter and install the new one. Make sure that the flow meter going into the UFH manifold is the same type.

After installing the new flow meter, tighten it with a spanner, close the fill and vent port, and remove the hose pipe. Reinstate the flow and return. Finally, bleed the manifold of your underfloor heating system.

It’s also important to set the flow rate for the loop length. For this, you can follow the simple instructions in the 2021Homeowner’ss Pack from Multipipe. Just remove the cap and open the manifold flow meter to achieve the desired flow rate on your UFH manifold, and you're done!
