§ Mr. Harold Walker
asked the Minister of Housing and Local Government if he will recommend the substitution of alternative materials for copper, wherever possible, and the use of thinner-walled copper tubing, where these materials are used for building purposes.
§ Mr. MacColl
The latest edition of the Ministry's model water byelaws will include two new British standards for thinner-walled copper tubes and my right hon. Friend is about to issue a circular to all water undertakers asking them to accept these new specifications.
The new model will also for the first time permit the use of stainless steel pipes and these again will be brought specially to the notice of all undertakers as alternatives to copper pipes.
My right hon. Friend sees no need at present for any other guidance to local authorities.
