PearlyButton, Re: Lead pipe. By the 1930's very little lead pipe was used here. Most old houses had zinc plated steel with dryseal taper pipe thread joints by the 1920's. I guess England imported lots of lead from the Malay States or some other colony. Or it may be the unions liked it as it was flexible and easy to use. There was some lead pipe used here in drains and lead was used along with oakum for the packing of joints in cast iron pipe, both pressure and drain. And of course the solder was 40% lead along with 60% tin when it was used for sweating copper tubing. I don't think I have ever actually seen lead pipe used for a domestic water supply but I have heard of it. I have three old industrial supply catalogs from the 1930's and only one of them even lists lead pipe and fittings. I don't think that your lead plumbing contaminates your water very much but if the water district screwed up and allowed the Ph of the water to go acidic it would begin to leach out the lead. Slagle
