putting tank in loft!!

[jase158]

I need to put tank in loft!! in my own home, I want to raise it for better pressure, loads of space in loft so want to raise it fairly high, whats the best way to make platform? not a big tank, but obviously don't want it to fall!!

So belts and braces to hold it up!!

 

[lambchop]

1 bar of pressure for every 10 metres. You maybe able to raise it a couple of metres depending how high your loft space is so a possible increase of 0.1 bar for every metre increase in height. Could be wrong as doing this off the top of my head mate

Marine ply, cls and some 2" 10s mate

 

[jase158]

so pointless!!
might just put it in loft then as need space in airing cupboard!!

whats CLS?

 

[wattsie1987]

whats CLS?

Canadian lumber standard. Used mostly for studs/first fix doesn't split as easily and nice to handle.

As mentioned 25mm marine ply deck. And CLS carcass from joists to trusses all four corners and counter batten against the joists to spread the load, build an internal platform inside that cross braced. Jobs a goodun!

Brilliant, thanks, didn't even think about trusses!! brilliant!!

 

[wattsie1987]

I meant to put rafters actually. If you have trusses tho all the better!

it's true that raising tank upon a time and money consumingly large constructed platform increases output at taps by a tiny degree, so why was it such a common practise?

 

[lambchop]

The op is a little unclear, I think it's a combined cyl and feed tank. He needs the space, put it in the loft. We needed more water compared to back in the day, larger cwsc, house prices more expensive, space a premium etc. there could be a really hood historical reason good knows what it is, I'm just speculating

 

[WaterTight]

But what is the worthwhile reason for raising it once in the loft? Tiny, barely noticeable increase in output at tap. And all it took was spending the time and effort constructing a platform.

 

[lambchop]

I think we have our wires crossed mate, that's why my first pointed out there's going to be hardly any increase in pressure for a lot of work. I don't think the op realised this

 

[WaterTight]

yeah no i get that. i'm more wondering why anyone ever did so in the first place.

 

[lambchop]

Lol most probably there were a lot of plumbers that needed the work, maybe one of the ye olde Skool can shed some light

Its yer own house so wgaf. Pull a couple of bits off the fence and fix it by pulling another bit off bwhen the wife complains the rse is going to fall out of it lol

 

[Ermintrude]

Un vented or a pump

 

[tamz]

As for why would you do it. If any of you have ever lived in a house with a gravity fed shower you would appreciate every foot matters. It doesn't matter a fuvk with the taps.
Personally i'd throw the tank in the bin and fit an unvented or a combi is cheaper to run.
No need to go around like the cobblers bairns.

So basically a tank raised in a loft is only ever there to turn a really rubbish shower into a vaguely alright shower?

 

[lambchop]

It's the way you sell it to them
it will be like standing underneath a Balinese waterfall

Thats about it

If you fill a couple of buckets lol

You're not wrong

 

[wattsie1987]

I seem to do this when a fortic and CWS are in the loft together feeding a pump and the hot ends up back feeding the cold through the shower valve. Some people just done get water levels and seem to think it'll be OK.

 

[Ermintrude]

If it's an elson type

Yes mild difference. If cylinder just lift headder tank and Decaale flanges

 

[jase158]

I have power shower so not needed for shower
kitchen hot basin hot and cold and bath hot and cold all really slow, (liveable)
toilet is slow to fill!! Needs sorting!!

So from what has been said it is pointless putting in loft as won't increase much!!
But I will be doing this anyway just to get rid of tank from airing cupboard!!
then the only issue is toilet!! So may put all colds on mains to increase pressure to cold on bath and basin!! Or just connect toilet to mains!!

Obviously power shower on tank and hot cylinder!!

Thanks for your help guys!!

 

[Plumbstar Tom]

going from 0.1bar to 0.5bar is a 5x increase

But for the time and effort to raise it I would vote a pump, whole house jobby, or redirect cold feeds to come from mains and shower pump

If you're taking it out of the airing cupboard for space then its not too much more effort to raise it when you site it in the loft

 

[Nostrum]

Sounds like you've got the wrong taps for the system!

Didn't really want to go into this much detail, but your right, old taps, limescaled like mad!!!
old steel pipe probably lime scaled like mad!!
but all under bath, so hard to get out!!

 

[stevetheplumber]

i disagree i moved my tank up about 6 ft and it made a lot of differencethis was years ago and ive gone to mains fed now which is obviously great but if your stuck with gravity it will be the difference between unusable and usable
