Moving water tank

Yakuza

Hi all,
Is there any major disadvantage to moving my water tank in my attic from where it is now (perched on a custom platform in them middle of the attic) back down to being on top of the joists (spreading the load over a load-bearing wall). The height difference is about 1 metre lower. I've no idea why it was perched up where it is (this was done probably in the late 70's / early 80's, l only moved in there in 2004). Most people I know in the area have their water tank level with the joists.

I have a shower / mixer unit in the upstairs bathroom and a Triton in the downstairs bathroom.

Would there be an appreciable drop in cold water pressure in the upstairs bathroom to warrant not moving the tank (I'll be getting this done by a plumber)? Moving it would free up a fair chunk of the usable space in the attic.

Any input would be welome

the 1m drop will be noticed big time, it about half what u have now.
also the longer horizontal pipe runs will reduce the flow.

In passing is the tank plastic or galvo steel: if the latter and u say it is there since the 70's u need to replace it and treat it with care before u do replace it.

Dont push at any 'bubbles' on the inside or outside.

It is plastic. The original tank was in the attic when I bought it, rusted away to nothing, rotting in the corner.

There wouldn't be much horizontal flow, in fact, less than there is now as the position I was thinking of is closer to the bathroom than the current one.

Thanks for your input
