Frequently Asked Questions:
Does McNelly Services provide commercial plumbing services throughout Chicagoland?
Yes. McNelly provides commercial plumbing services for businesses, property managers and commercial facilities throughout the Chicagoland area. Services range from routine maintenance and repairs to larger plumbing installations, underground work and emergency service.
Does McNelly Services provide 24-hour emergency commercial plumbing service?
Yes. McNelly provides 24/7 emergency service for commercial plumbing problems. Prompt professional attention can be especially important when a plumbing failure threatens business operations, tenants, inventory, equipment or the surrounding property.
What are common warning signs of a commercial sewer problem?
Recurring drain backups, slow drainage, unusual odors, gurgling drains and repeated plumbing problems can indicate a larger sewer or drainage issue. Because several different conditions can produce similar symptoms, recurring problems should be professionally evaluated rather than repeatedly treating only the immediate symptom.
Can McNelly Services inspect commercial sewer lines with a camera?
Yes. McNelly provides sewer televising services that allow plumbing professionals to examine conditions inside a sewer line. Camera inspection can help identify blockages, deterioration and other problems while providing better information for determining an appropriate course of action.
Does McNelly Services provide RPZ backflow testing and service?
Yes. McNelly provides RPZ backflow testing and related commercial plumbing services. Backflow requirements can vary by system and municipality, so property managers should follow the testing and documentation requirements applicable to their particular property.
Can McNelly Services provide preventative plumbing maintenance for commercial properties?
Yes. Preventative commercial plumbing maintenance can help identify developing problems, maintain drainage systems and reduce the likelihood of unexpected plumbing disruptions. The appropriate maintenance schedule depends on the property, plumbing systems, usage and operating environment.
