You can ask your friends, neighbours, family, and coworkers what plumbers they have used. You will often receive good recommendations and learn about the quality of their work. You will also learn about bad experiences so you will know what company to avoid. You can also check with people in your social circles such as church members. As well, you can also check with a realtor to see if they have a list of dependable and honest plumbers.

Draw up a shortlist of plumbers using a local directory. Online directories will provide you with contact information, reviews and the plumbers' websites, so you can make sure they are suitable.

Certified. Just like any other professional, a plumber comes with a certification. Make sure that you hire someone that is fully certified as a slow drain specialist. Never assume that all plumbing companies that offer these types of services come with a certification. Do your research.

Ask for written quotes and compare the quality of their services and rates. Lower rates are not always the better choice. Sometimes, those plumbers who offer lower rates provide low quality services and materials, too. Written quotes are also important to give you an idea of what the Trustworthy plumber are going to do and how much are you going to pay for those services.

Your septic tank has to be emptied sometimes, and there's no easy answer to when it should be done. It depends on the size of the tank and the (sorry to mention it) consistency of the stuff going into it. Basically, if the septic tank isn't pumped out regularly, it will cause you thousands of dollars worth of problems. Ask your Local plumber for advice on your septic tank maintenance.

Kitchen sink drains are usually plugged by food particles. Discretion should be exercised in using a garbage disposal. Tough and fibrous food like corn husks and onion skins should not be run through the disposal. Large amounts of potato peelings can also cause problems by forming a thick slurry.

Hourly fees are another thing you want to check out before you hire a plumber. Call around and get a few estimates for a job. Ascertain if the plumber is willing to sign a quote and give you a price warranty before he begins working. You should also find out if the plumber will require you travel time to and from your job and how they will compute that time and prove it to you. Giving you a precise price may be challenging, but any plumber who can't give you a comprehensive explanation of how you will be billed with an estimate of the cost should be avoided.
