The Brew Cabin

i am considering building a conservatory,the kitchen sink and washing machine pipes come directly inside the new conservatory,how can i hide these? someone suggested inserting the waste pipes through the cavity and into the back of a bottle gully.if i do this do i leave the top of gully at ffl with a sealed lid? this has puzzled me for some time,hope you can help.

If you feed pipes aliong the cavity you create problems of access in case there was to be a problem, and you;re effectively bridging the cavity. That's why it's not done 'in the trade'.

The normal method would be to 'box in' the exposed pipes, which are only 40mm waste, and there's no problem connecting them to a 'Top Hat' connector, which directly links 40mm waste to 100/100mm FW drainage with no need for a gully. However, an access point further downstream is required.

The 'Top Hat' can be hidden at the base of any 'boxed-in' pipework, making it completely unobtrusive.

great thanks for your reply,but is a top hat like a hopper? i think i understand no need for gully is this because there would be a sealed lid?
cheers for your help

A 'Top Hat' is a special coupling that directly connects a wate pipe or downspout to an underground drain. Different manufacturers have different names for them; some call them rainwater or wastewater couplings, or adaptor couplings, but we've always referred to the, generically, as Top Hats as the one used for connecting a SVP to a clayware FW system bears something of a resemblance* to that famous titfer.
