probrox Posted July 28, 2009 Share Posted July 28, 2009 This is a question for some of the builders on here. I am installing a shower at the moment and i have recessed the pipework into the wall. I am going to fill around the pipes with hardwall but i was just wondering if the copper pipes will need to be protected against corrosion, and if so, with what. Also, will the expansion/contraction of the pipes blow the hardwall? Once filled the wall will be tiled if this makes any difference.

L33 Posted July 28, 2009 Share Posted July 28, 2009 on new builds the only time they use copper is where its on show, as soon is its under the floor or behind walls its plastic! Quote Link to comment Share on other sites More sharing options...
Havard Posted July 28, 2009 Share Posted July 28, 2009 Plastic pipework is the way forward. The copper will expand and contract more and will cause problems in the long run mate..!! H. Quote Link to comment Share on other sites More sharing options...
edge Posted July 28, 2009 Share Posted July 28, 2009 If you have a hot and cold to the shower you may get some condensation but nothing to worry about. Becareful when fitting plastic push fits to showers as some manufactures wont touch it if it has i.e some books say copper compression fittings must be used where the water supply connects to the shower You can also use copper compression fittings on plastic pipe.

peter richards Posted July 28, 2009 Share Posted July 28, 2009 isnt it just a cold feed , if not you can put a bit of lagging around the pipes, sponge tubing then fill in the lagging will compensate for any expansion Quote Link to comment Share on other sites More sharing options...

Jimmer Posted July 28, 2009 Share Posted July 28, 2009 You can also use copper compression fittings on plastic pipe. Only with correct inserts and suitable compression fitting. Quote Link to comment Share on other sites More sharing options...
