Clearing a clogged drain in Louisville
The fixture count tells the story. One slow sink is a branch clog, and a cable usually clears it. A tub, a toilet and a floor drain all misbehaving together means the line they share is the problem, and the camera comes out.
Kitchen grease and wipes build up fast in older lines. A visit runs from a cable pass to a jetter, and a camera lets you see the pipe wall on screen. You can also compare stoppage work for tubs and sinks on its own page.
Louisville sewer line repair and the city's permit rules
A recurring backup, a sewage smell in the yard or a wet patch over the lateral all lead to the same step: a camera inspection. If the pipe is cracked or bellied, a repair on private property needs a city permit, and street or right-of-way work goes through Public Works.

Faucets and toilets in Louisville homes
A dripping cartridge, a toilet that runs after flushing and a showerhead that sputters are common calls, and most take one visit. Louisville's older homes often have fixtures that no longer have exact replacement parts, so a plumber may suggest a swap instead of another patch.
Burst pipe and water damage in Louisville
Stop the flow at the main, shut off the water heater if it is involved, and photograph what is wet. Once the plumber has stopped the leak, drying and cleanup follow. You can also compare wet drywall and flooring work on its own page.
Water heater installation in Louisville
Louisville lists water heaters among its permit items, and the work is reviewed on a same-day or next business day basis. The city's policy for gas appliance replacements also requires 90 percent or higher efficiency for replacement water heaters, and the exhaust vent pipe must be pressure-tested and inspected before final connection.
Tank size and the choice between a standard and a tankless unit come up at the visit. You can also compare replacing a leaking tank on its own page.
Other calls in Louisville
- Garbage disposal: replacement or a jam clear, normally under an hour.
- Tankless water heater: gas line size and vent path decide the swap.
- Water heater repair: element, thermostat or igniter replacements.
- Water softener, slab leaks, gas lines, leak detection and repiping: one-line summaries here, full pages on the hub.
Water line work is covered too
A replacement water line is a job for a plumber with an excavation plan. In Louisville the city owns the street side, and private-side work needs the permit noted above.
Louisville water source and the 10-foot rule
The city treats South Boulder Creek water and Northern Colorado Water Conservation District supplies at two plants. For homeowners, source facts matter mostly in two ways: a main break near your street may shut water briefly, and the city's own standards govern how new lines are laid.
| Topic | What the city says | What you do |
|---|---|---|
| Water and sewer line spacing | Lines must stay 10 feet apart in design standards | Ask the plumber how a reroute keeps that gap |
| Permits | Contractor must hold a Louisville license | Confirm before work starts |
| Street work | Contact Public Works | Do not dig in the right-of-way yourself |
- Keep the plumber's permit number
- Note the date of the final inspection
- Know where your shutoff sits

Louisville permit, inspection and water questions
Does Louisville require a permit to replace a water heater?
Yes. The city's permit list shows water heaters and standalone plumbing work as permit items, and sewer or water repair on private property needs one too. Same-day permits for water heaters and minor plumbing are usually issued the same day or the next business day.
Can a plumber do the repair first and file the permit later?
No. The city's policy page warns that work started before a required permit can bring higher permit fees and stop-work orders. The permit comes first, and a plumber working in the city must hold a current Louisville contractor license.
Does Louisville's inspector visit me for a water heater?
Louisville's building department does not inspect furnaces, air conditioners or water heaters directly with homeowners. Those inspections follow a separate procedure that the plumber and the city handle, so you mainly need to leave access to the unit.
Where does Louisville's water come from?
South Boulder Creek and supplies from the Northern Colorado Water Conservation District. Two city plants treat it, the Sid Copeland plant in the north and the Howard Berry plant in the south, which the city says have a combined capacity of up to 13 million gallons a day.
What does the 10-foot rule between water and sewer pipes mean for me?
Louisville's design standards require water and sewer lines to stay 10 feet apart where they are built. It matters when a replacement line is rerouted in a yard, because the plumber has to find a path that keeps that spacing.
