# Original Thornton Plumbing: Finishing Half Done Repipes In the oldest part of Thornton we spend a lot of time on houses where the visible pipe was replaced years ago and everything behind the drywall was left alone. - Branch replacement where earlier work stopped short - Hall closet water heater replacement done to code - Available 24 hours across the north metro ## Why do so many Original Thornton houses have mixed piping? Original Thornton is the city's earliest tract housing, and most of those houses have had at least one round of plumbing work. The common pattern is that a previous owner replaced the runs that were visible in the basement or the utility area and left the branch lines inside the walls untouched. Afford-A-Rooter Plumbing finds where that earlier work stopped and prices finishing it against living with it. ## Key takeaways - Replacing only the visible pipe leaves the oldest and least accessible sections still in service, which is why pressure improves and then disappoints. - A house with good flow at the laundry sink and poor flow at the far bathroom almost always has an untouched branch behind a wall. - No alley access in this part of Thornton means materials and equipment come through the front or the garage, which affects how the work is staged. - Afford-A-Rooter Plumbing works under Colorado Master Plumber licence MP-18927 and takes north metro calls 24 hours a day. ## How do I tell how much of my house was already repiped? Compare fixtures. Run the tap nearest the water heater, then the one farthest from it, and note the difference. A house that is uniformly slow is uniformly old. A house that is strong in one place and weak in another has been partly done, and the weak fixtures are hanging off whatever was left. We confirm it with a pressure test and a look at every accessible connection. [Partial repipe options](https://www.affordarooterplumbing.com/partial-repipe-options) explains how the remaining work gets scoped, and [galvanized pipe replacement](https://www.affordarooterplumbing.com/galvanized-pipe-replacement) explains what comes out. ## What is the situation with hall closet water heaters? A lot of these houses put the water heater in a closet off a hallway rather than in a basement. That is a compact arrangement and it works, but a gas appliance in an interior closet needs combustion air and a correct flue, and both are things that get compromised when a house is insulated, re sided or has its doors replaced. We check the whole arrangement when we swap a tank rather than just fitting like for like. See [water heater replacement](https://www.affordarooterplumbing.com/water-heater-replacement) and, where the closet is genuinely too tight, [tankless water heater installation](https://www.affordarooterplumbing.com/tankless-water-heater-installation). ## What happens to the drains in these houses? Cast iron waste, long horizontal runs, and decades of use. The failure is gradual rather than sudden, and the symptom people notice is a bathroom that has always been a bit slow finally becoming a bathroom that will not drain. Cabling clears the immediate blockage. A camera tells you whether the line is scaled, bellied or holed.

The remaining original branches are where every future failure will come from, and the accessible half is already done, which brings the cost of finishing down. **Why is one bathroom fine and the other terrible?** Because they are fed by different branches and only one of those branches was replaced. Uniform age produces uniform symptoms, and yours are not uniform. **Can a tankless unit go in a hall closet?** Sometimes, and it depends on gas supply, venting route and clearances. We assess all three before recommending it rather than assuming it will fit. **How do you get equipment in with no alley?** Through the front or the garage, and we plan that before the day rather than discovering it on arrival. It affects staging more than it affects cost. **Are you licensed to work in Thornton?** Yes. The work is carried out under Colorado Master Plumber licence MP-18927 and Colorado plumbing contractor licence 2110. --- Source: https://www.affordarooterplumbing.com/neighborhoods/original-thornton Afford-A-Rooter Plumbing, 10860 N Dover St STE 2300, Westminster, CO 80021.
