Megaflo with internal air bubble.

[jase158]

Mega flo 170l, leaking from t&prv, drained down and refilled to recreate air bubble, still leaking, all thermostats/ valves working.
grenade style valve, leaks when water reaches 50 degrees.

Books say that they can be adjusted but i cant see how!!
also how do you know that it isnt the baffle in the cylinder that is broken?

I am G3 registered!!

just needed to confirm, thank you. changed the thermostat a month ago, all working fine then suddenly this goes and thermostat has gone again!!

if the thermostat is gone is likely that is over heating , how did you read the 50 degrees temperature ?

sorry was the immersion thermostat that has gone, cylinder thermostat is what i got reading from, t & prv drips at 50 degrees, broke my thermometer so couldnt tell reading at tap but it wasnt hot enough to burn. I am just curious how do we know its not the baffle inside the cylinder? is the only way to test it by putting new t & prv on?

 

[SafeGasInstall]

does it drip when you pressurise it or when start heating it ?

 

[SafeGasInstall]

I dont think the internal baffle can fail , how old is cylinder ?

 

[jase158]

Only when temp reaches 50 - 55
