The broken pipes will and then need to be repaired or replaced and the soil, reinforced concrete slab and flooring reinstated. This obviously causes a lot of mess and disruption, and requires significant labour, which tin push the overall neb up considerably.

The near common blazon of pipe used for pressurised h2o lines nether house slabs is copper tubing, but as the copper ages information technology is prone to pitting, corrosion and thinning รข€" all of which lead to leaks.
