Hot tank drain

[rocketmanbkk]

Hi Friends

Can I ask this one please?

If a hot water storage in the bathroom needs draining but there is no drain off valve and I just run the hot taps will it drain fully?

The chap needs his immersion changed but it's all very old (same as him) and he's skint!

Cheers

Rct

old sort of means vented so no it isn't drained get into the open vent with a hose and syphon out

It's one of those fortic tanks. Cold water above hot (combi I call it).

All you will do by opening the taps is drain the pipework, the cylinder will still be full. As said above, cut the vent and syphon enough out to enable you to change the immersion.

Can you not slide a hose down the cold feed from the top and syphon ot out?

I'm not sure about that kingb.

The top is up in the cupboard and very hard to get to.

If you look at something and you're not sure, snap photos so you can have a visual think about it or us to also have a look

its what i do.
how is the hot connection piped?

In the side, I think I'll need to run hot taps and when stopped undo the hot feed, put a hose in to bottom and suck then shove other end in bath.

Have a decent aquavac ready as it will drain level to the connection.
you can use the aquavac to start the sython on the hose.
also the smaller rhino flexi tubs are good to have on hand

Those fortis tanks have the cold feed & vent all built within the insulation normally... Might be a pain without the drain off, probs hidden around back! Get the wet vac out!

Cheers but can't get to the top tank. Too enclosed.

How would you change the ball valve?

 

[rocketmanbkk]

Excellent question Leo and one I asked the old boy. He said it's never been changed.

Only way if you can't get to drain or tank, is to undo the immersion and wet vac the water until its empty.

Two wet vacs and a helper or a 120l wet vac?
