Heatrae Sadia HOTFLO10



Hi Guys

Electrician by trade so this is out of my territory so I thought i'd canvas advice, a customer of mine has two Heatrae Sadia Hotflo 10 multipoint water heaters 6 years old, about 6 months back one started running into the overflow, now the second has too.

The water is coming from an elbo shaped valve with a black knob marked 6bar teed off the cold inlet which I guess is a releif valve, adjustment makes it worse, there is also a pressure reducer and a pressure vessel.

One heater is to be replaced by oversink model so no worry there - but on the other one do you think its the valve gone or should I replace anything else at the same time to prevent another visit.
