How to not bu**er the boiler?

[davhill]

Hello folks,

Being about to change the basin in the downstairs shower room so I have to shut off the water
and go into both the hot and cold feeds. I know how to turn off the rising main at the stopcock
but I'm wondering what to do re. the boiler.
It's an Ideal Isar HE30 and we have an arrangement, I leave it alone and it works.

But having had dark warnings about frying the boiler, here's the plan I've formulated...

1: Switch off boiler at the I/O switch on the user panel.

2: Shut off the stopcock.

3: Open the cold tap nearest ground level.

4: Open the hot tap in the same spot.

5: Carry on regardless.



The old basin is one of those tiny triangular jobs that's too petite to be used by human beings. So, I got a floating basin (18" x 22") with a semiped. The plan is to fit the basin, move the connexions across about a foot and rig it up. The feed pipes are in plastic and I've
discovered they're in Uponor (16.7mm O/D).



I have to sink the pipery into a trench in the wall so they can run down to the skirting level pipe box.

All I need to know is if the above plan is OK for the boiler so it can't fire dry or anything.

Thank you, David.

You will be ok just make sure you have fittings to adapt the upnor pipework before you start get the hot and colds moved to the new position valve them off refill the hot and cold system pipework vent and test your handy work before you even start installing anything else and switching boiler back on .

The boiler won't fire without sufficient water pressure so no fear of frying it.

Well thank you, people.

I'm further on now. The feed pipes have little blue > signs printed on them so this may help.



I've managed to hoik out the old basin and cabinet. I thought that's all it was but it was like shifting the Empire State Building. Perseverance won out. Here's what I have now...


The waste pipe is gummed togther with solvent and it's rock solid. The O/D is 37mm.

Closer look...



The R.H. pipe ambles off down the pipe box to the electric shower so it must be the cold. The hot comes in from the left and is attached to a copper feed pipe.

Here's the new basin.



And here's where it's going...



The left wall will be the 'back' wall so the connexions will be about eleven inches in
from the corner. The semiped comes down 14 inches from the location under the basin. I'll have to sink the feeds and drain into the wall from just under the base of the semiped to the floor. Then, I can then extend the pipe box into the corner - the floorcovering is to be replaced with Cushionflor.

I already have the basin mounting kit...good job I bought a 14mm masonry bit to secure my gun safe!

Bottom line, so far so good. I'll keep youse posted!

Shaun was right again it is indeed speedfit 15mmm so compatible with 15mm copper various ways to do it but sure you will find what suits you best cheers kop
