If you ever have plumbing related issues, always call your public utility first
Many people automatically call a plumber first. In reality, many public utilities will show up to inspect the problem and tell you whether they can fix it. If they can, generally this is included in the bill that you pay the utility monthly. If they can't fix it, they will tell you to contact a plumber, no charge. Plumbers will generally show up and charge you money just for showing up even if it's a problem the public utility can fix.
