Hot water advice please

[rocketmanbkk]

Hi Friends

Fitted new kitchen mixer earlier, all simple as ballofix on hot & cold (makes a change).


The hot ballofix is weeping.

Vented system, the hot has a gate valve under the sink but it's seized.

No other valves on hot.

So, shall I just turn cold feed to hwsc (in place & turns) & run hot taps until water ceases? I can then change both ballofix & gate valve at the same time.

Is this ok to do? Again it's the air lock anxiety issue!!!

Cheers

But can result in implosion which is why we wouldnt bung the vent [emoji3]

which is what i said in post #15 :smile5:

Ah by implosion do you mean that the water pours out of the open pipe?

or collapse of the hot water cylinder itself? Just wanted to know what terminology you mean

What can happen if you bung the vent

 

[Leo21]

What, they multiply?

 

[kay-jay]

Cylinder collapse pal. Like what tamz pivture shows.
Im sure it would make water come out of your pipe at same time [emoji3]

Don't be a wuss do it live, make sure you've got wellies on though:smartass:

Why do some people fit cold feed valve below DHW draw off level, puzzles me?

 

[PlumbersMate]

Not every time, you can still get an airlock. Time to get the wet vac out if it does airlock.

That's why I said prevent, not completely eradicate all chances of an airlock

 

[Leo21]

Surely if the bungs hold, the only way a cylinder can implode is if you only bung the vent and then run a tap?
