The ajax valve for our hot water cylinder is leaking water out of a orifice beside the pressure adjusting screw. See photo.

Can this fault be fixed or does the valve need to be replaced?

 

Thanks in advance

Replace diaphragm in valve or whole new valve.

Thanks. 

 

I think I'll go the diaphragm route depending on price of that against a completely new valve.

 

It is a Nefa valve, you could probably tell from the photo. I see you can buy a service kit, a diaphragm assembly or just the diaphragm. Which do you think is the best option? I was hoping to do it insitu. Is the diaphragm assembly the bottom half including the black housing?

There are no "ajax" valves.

 

There are Nefa or Apex.

Aredwood: Replace diaphragm in valve or whole new valve.

 

Replaced the diaphragm and the jumper washer. $20 worth of parts. Took me about an hour from rounding up my tools to turning the water back on. As a bonus there was enough room to do it insitu, so no fluffing around with hemp.
