Sewer Line Repair and Replacement

Sewer line issues often show up as recurring backups, multiple slow drains, gurgling toilets, or sewage odors. Whether the issue is a blockage, a damaged section of pipe, or a failing line, TLH Plumbing can diagnose the problem and recommend a repair or replacement that restores flow and helps prevent repeat problems.


If your home or business has frequent sewer backups or slow drains throughout the building, it may be time to look beyond a basic drain cleaning and address the main line.

Water Line Repair and Replacement

A leaking water line can waste water and cause hidden damage to your yard or foundation. Common signs include sudden low water pressure, pooling water in the yard, unusually green patches of grass, or an unexpected increase in your water bill. Our team repairs and replaces water lines to restore safe, reliable water service and steady pressure.

Grinder Pump Service

Grinder pumps are often used with septic systems and can be critical for moving waste to the right location. When a grinder pump fails, you may experience backups, slow drains, or system alarms. TLH Plumbing provides grinder pump installation, repairs, and maintenance to help keep your system working properly.

Underground Gas Utilities

Underground gas work requires careful planning and a safety-first approach. TLH Plumbing provides underground gas utility plumbing services as part of broader projects and repairs when included in scope. If you need underground gas line support for a property upgrade or new equipment connection, we can help evaluate the safest path forward.
