Some plumbers might be forthright when it comes to offering advice for preventive care. Others may not want you to know that your current repair, which is helping to pay your plumber's bills, is something you may have been able to prevent. Technically, the plumber's job is to fix a problem, not offer you advice on how you can help make him obsolete. But there are many plumbing issues that you can avoid with preventive care and you're likely only going to find this kind of advice online. If you have a plumbing repair you need done, take some time to look up the issue online and see if you can save yourself some money down the road by taking some early measures to avoid it.
