I am currently in the process of installing a megaflow HW sytem to serve a bathroom with separate shower and a separate shower room with body jets. Will 22 mm pipe give a sufficent flow rate to enable both showers to be used or do I need to put a 22 mm pipe to each or possibly a 28 mm divividing into two 22's any ideas would be welcome thanks
22mm pipework should be ok. Most important part of the system, is the incoming water main (25mm mdpe plastic into the stopcock & then 22mm pipe up to the megaflo. This will determine how much water the megaflo will deliver, try their website & look for flow rates.P S don't forget to balance the cold water outlets especially bathrooms/shower. Megaflo's are pressurised hot water cylinders and the manufacturers instructions should be followed! Very dangerous in the wrong hands
