Drain point for Central Heating

[AMEdinburgh]

Is there anyone that can advise me.

I'm working along on my first fix for my radiator CH in a new extension which will have it's own boiler and need to install a drain point. My problem is there is not a nearby drain outside and I would not want to discharge the liquid onto the new paths we've laid around the property and onto the new turf, recently laid.

I have an underfloor 110mm drain just below one of the traps in one of the rooms and the CH pipes nearby. Is it permissable to T off a 22mm isolator off either the supply or return (which is best?) and connect it via a bit of clear pipe two hosetails and a glued strap on boss into the main drain or does this break the rules.

Thank you

We do but it would end up being quite a run with almost no fall to the nearest point to discharge, hence wondering whether to do something other than the drain point at the bottom of an outside wall.
