Sorry in advance for the boring topic. When Thames Water announced the local round of water mains replacement, they stated that electrical earthing could be affected because some properties' electrical system are earthed to the water pipes and, with the change to plastic pipes, the quaility of the earthing wcould be affected, leading to possible electrical problems. Now that several roads have been completed, i would appreciate knowing if anyone has actually had to remedy their earthing or whether the proctice of earthing to water pipes is all that widespread?
thanks!
