An experienced plumber is a godsend if you have a plumbing emergency. Always hire a plumber to fix; install or replace plumbing, as attempting to sort the problem yourself can end up causing more damage. Faulty or blocked drains are unpleasant, so you should make sure they are properly looked after and call a drain maintenance specialist if you have a problem. In rural areas it is not uncommon for people to use septic tanks, if you have one make sure it's regularly serviced. Water softener systems are also worth considering as they can make your heating system more efficient.
