Ask around. Ask your friends, ask your neighbors and get referrals. Nothing is more powerful than the testament of someone who has had a local plumber in their home and can speak to his/her capabilities.
If your service provider has adequate knowledge and training on the topic, this might be a good time to find out more about energy alternatives. He may be able to install low-flush toilets and lower-output shower heads. This is also a good time to talk about solar thermal water heating, though perhaps before the roofer is finished up top.
In order to summarise the best plumbers to call out to repair your condition running toilet will be the plumbers who are able to get to you the quickest provide you with a reasonable cost and have the expertise to carry out the job and complete it correctly.

Trustworthy. The best way to find a Trustworthy plumber is to ask a close friend, family, or a good neighbour for recommendations. They're the best people to ask because they've experienced the services first-hand and they will never lie to you about it. This works in the same way they won't let you hire someone who has worked for them and delivered bad service.
The number one thing to look for is emergency services. You never know when a pipe will burst or a toilet will overflow. It is not always during business hours, and you certainly cannot wait hours until a Local plumber is ready to come to your home in the morning. You need someone who will be responsive when you need fast help, which is why you should look for a company that provides emergency hours. You may have to pay an extra fee, but it is usually cheaper than having to pay for mold elimination down the road after letting standing water stay in your house for days.
As precautionary measure, you have to tell all your tenants where their individual water shut off valve is located, as well as the entire building's so they can turn it off in case of emergency. And don't forget to make them accessible. It won't do any good if they know where it is but it's locked and they can't break in.
