Hep2O® - Connection to Incoming Service Pipes

Connection to Incoming Service Pipes

Water may enter a property through a variety of pipe materials. In recently developed properties the water is typically brought to a residence in blue MDPE (medium density polyethylene) pipe. However, in renovation of older properties this pipe may well be made of one of a number of metals. The method of converting from the service pipe to Hep2O® differs depending on the pipe material of the service pipe.

The following guidance is applicable to blue MDPE Pipe to BS 6572:-


Figure No. 49 Rotatable Stopcock	Figure No. 50 Non-rotatable Stopcock	Figure No. 51 Rotatable Stopcock

Notes:
	Where a common supply pipe serves two or more dwellings a double check valve (Code HX72) is required directly after stopcock in each dwelling to comply with Water Byelaws.
	A drain-cock (Code HX32) should be fitted immediately after stopcock or after double check valve where provided to comply with Water Byelaws.
	For sealing screwed joints on adaptors apply PTFE to threads.

Alternatively a PE (polyethylene) to copper compression stopcock can be used. The information on using compression fittings on Hep2O® pipe should be carefully noted.

For metal pipes an appropriate stopcock should be used with a compression outlet to 15 or 22mm copper. Hep2O® can then be fitted directly to these outlets carefully noting details in Connections to Compression Fittings.
