Unvented OSO SX - Mains supply

[tigboy]

Hi All

I will be getting an OSO unvented cylinder at some point and I'm trying to plan out my bathroom plumbing.

The installation manual ask for an uninterrupted 22mm main feed which i can run easily as i currently have no ceilings. It then informs me the balanced cold should only be used for mixer showers and bidets.

So my question is where do i get the other cold feeds for the toilet, bath etc?

For ease of use, I’d like to tee off the 22mm cylinder feed as it passes right by the bathroom. But i think the correct/best way is to tee just before the PRV on the top of the boiler.

Any help much appreciated!!

I haven’t heard that before with shower mixers and bidets. Have you spoken to your installer?

No not yet, this is what the manual said in a CAUTION BOX -

Do not use the balanced cold connection to

feed any outlets other than mixer showers

and Bidets. Under no circumstances use the

balanced cold connection to feed all cold wa-

ter outlets as this practice contravenes Sec-

tion 10 of water regulations.

Unless its just means don't go down to your drinking tap?

It must mean that a tee off before it is balanced is to be fed to all other outlets.
