[biglug]

i'm extending my kitchen and need to move my outside tap. where the pipe has to be laid i will be covering it with a concrete floor. will the concrete corrode the copper pipe, if so is their a special pipe i should buy.

When copper pipes are laid in solid floors they must be protected against failure by movement of the floor.

Methods used to protect copper pipes:

1 A plastic sheath set into the floor with cement mortar. No joints should be located in the sleeve.

2 Burying - Pipes which have been protected laid on top of base concrete and covered by a screed. Pipes up to 28mm may be buried and a minimum cover of 20mm must be applied. When pipes are to be buried in magnesium-oxy-chloride cement or magnesite flooring copper is the only material recommended (BS6891) and must be factory plastic coated.

Any pipe carrying mains water has to be in a purpose-made conduit anyway. And yes - concrete WILL corrode copper and it MUST be protected.

Ditto as croydoncorgi has said, concrete WILL corrode copper

I would never bury a pipe in a floor (or wall) unless there was no option.

If I had to though I would use plastic or copper pipework in a pipe in pipe arrangement with no joints. That is the only time I would choose to use plastic pipework.
