Hiya,

Can you explain some more about what you are trying to do?

What key and nut is it you are referring to?

 

Thanks

pressure on my boiler has dropped to bottom of red area in order to raise it i have a plastic key with 2 o rings on it . Ihave to insert this key into a circular hole on underside of boiler. to the right is a nut which i have to turn anticlockwise to allow more water into boiler and raise pressure. my main problem is how to engage key properly.key tip is circular with two protruding pieces opposite one another. hope this is good enough explanation.

Hiya,

OK, thanks for that.

this is something the plumber/installer has put in.

The filling loop is normally 2 valves.

You open both valves and watch the gauge until it's at the right area then close the water valves.

 

I can only assume the nut is one valve and the other is key operated.

 

Can you post up a picture of what you have? I may be able to assist further if I can see what it is you have.

 

Thanks

sorry i'm bit of a novice where computers are concerned.do i assume that both of these valves would have to turn in the same direction in order to work. seems i'm a bit of a novice with boilers as well. technophobe comes to mind.!

Hiya,

It really depends on the valves used.

Lever valves can be turned 90 degrees clockwise or anticlockwise to open.

Screw valves are anti clockwise to open and clockwise to close.

 

Good luck with it.

Thanks
