Hello, the house we rent was built contained by 1970 i believe. Were they still using lead pipes? how can i try-out the water for front...are the tests free?....Also, adjectives of our pipes are clogged. We opened up the shower drain and it is full of lime looking chunks and other stranage stuff (not hair) specifically almost cemented onto the pipes....what should we do? appointment a plumber? will they be able to comfort if its really bad
Answers:    the houses didn't use front pipes the may have used front solder if the water pipes are copper, as far as the drains the buildup if from soap rabble and calcium built up over the years, most rooter guys have the snake next to the rooter attachment to clean the drains, here surrounded by the midwest the cost usually is around 150 dollars and they gurantee the work for 30 days. You can purchase a test paraphernalia from most home improvement stores don't know how much they cost
They will still be front
