Residential Plumbing Services
Comprehensive residential plumbing solutions across Aurora and the Denver metro area.
Residential Plumbing Repair in Denver and Aurora
Most plumbing problems don't wait for a convenient time. A pipe lets go at 11 p.m. A faucet that dripped for a month turns into a puddle under the sink. A toilet runs all night and shows up on your water bill.
We fix all of it. 303 Drain Now is family-owned, founded by Master Plumber Harold Watts, and we've been keeping water flowing in Denver homes for more than 25 years. When you call, you get a licensed plumber who explains what's wrong before any work starts and a price you agree to first.
What We Repair
- Leaking, burst, and frozen pipes
- Faucets, fixtures, and shut-off valves
- Toilets that run, rock, leak, or won't flush
- Garbage disposals and dishwasher connections
- Water pressure problems and pressure-reducing valves
- Sump pumps and ejector pumps
- Outdoor hose bibs and frost-free spigots
- Water and sewer line repairs
- Repiping for older homes still running galvanized steel
Every visit includes our 40-point inspection. We look at the whole system, not just the part that's broken, so you find out about the small problem now instead of the expensive one later.
Common Residential Plumbing Problems in Denver & Aurora Homes
Hard Water
Front Range water carries a lot of mineral content. Over time that scale builds up inside pipes, fixtures, and water heaters. It shortens the life of everything it touches and it's the reason your showerhead clogs and your faucet aerators crust over.
Shifting Soil
The expansive clay under a lot of this metro swells when it's wet and shrinks when it dries. That movement puts steady stress on buried water and sewer lines, and it's why a house that's been fine for 30 years suddenly has a break.
Freeze and Thaw
Denver can hit 60 degrees on a February afternoon and 12 degrees that night. Hose bibs, crawlspace lines, and pipes on exterior walls are the first to split. Most of the burst-pipe calls we run in winter come from lines that weren't shut off and drained in the fall.
Older Housing Stock
In Denver neighborhoods like Park Hill, Congress Park, and Berkeley, we still find galvanized supply lines and clay sewer pipe. In newer Aurora subdivisions — Southshore, Tallyn's Reach, Saddle Rock — the issues run different: builder-grade fixtures, water pressure, and sump systems.
