High-Rise & Sovent Drainage Plumbing
Condo towers, hotels and multi-unit buildings need a plumber who understands stacks, risers and pressure zones. Our owner has helped build the plumbing inside Las Vegas towers and knows how these systems work.
Experience Inside Las Vegas High-Rises
Tall buildings don’t plumb like houses. Many Las Vegas towers use Sovent, a single-stack drain, waste and vent system with special aerator and deaerator fittings that let one stack do the work of two. Repairs on Sovent systems have to respect how those fittings manage air and flow, or the whole stack can start to back up and siphon traps.
TPM works with building engineers and property managers on stack repairs, domestic water risers, booster pump and PRV stations, and planned shutdowns scheduled around residents and guests.

Frequently Asked Questions
What is a Sovent plumbing system?
Sovent is a single-stack drain, waste and vent system used in many high-rise buildings. Special aerator fittings on each floor and a deaerator at the base let one stack carry waste and air without a separate vent stack.
Can any plumber work on a Sovent system?
It takes experience. Sovent fittings manage air and flow in specific ways, so repairs have to be done correctly to avoid backups and siphoned traps.
Do you schedule work after hours?
Yes. We coordinate shutdowns and major work with building engineering, often after hours, to limit disruption to residents, tenants and guests.
Do you work for property management companies?
Yes. We work with property managers, HOAs and building engineers on service calls, preventative maintenance and projects.
