The Brew Cabin

hi, im currently in the process of installing some new pipework, downpipes from new garage and drainage from new retaining wall both to join into new 110mm pipework
my main problem now is how to connect into an old (still connected ) clay drain pipe, on a combined system i beleive this must be a trapped connection would a bottle gully be the answer im looking for.
o/d of clay drain is approx 130mm

A trapped connection must be used when connecting surface water pipes to a foul or a combined system. This can be done by means of a single trap where the SW system links to the Combined System, or by using trapped gullies at all pick-up points. If your proposed Bottle Gullies incorporate a trap, then they will be fine.

Linking new pipework, whether it's clayware or uPVC, to older, salt-glazed pipes requires an adaptor coupling, which you should be able to get from any decent Builders' Merchant.

hi tony
thanks for your reply , im now going for a P trap at the sw/ combined system connection point with new rodding point on the sw side i,ll then be able to rod to both sides of the P trap unless you see any problem with that ?. congratulations on a great website

Sounds fine to me. :)
