Call nowHow Milliken’s water heater Counter Permit works
In Milliken, “Water Heater” is a Counter Permit, applied for on the Town’s CommunityCore portal, and the Town says Counter Permits may take 24 to 72 hours for approval. The submittal asks for:
- the online application
- the recorded deed
- plumbing or mechanical drawings
- the manufacturer’s installation instructions
- a plot plan
SAFEbuilt acts as Milliken’s building official and inspector (970-305-3161). To pull permits, a plumbing business needs a Town of Milliken license, and it gives its plumber’s Colorado license at submittal. We list the Town’s permit fee on your quote.
Can homeowners replace their own water heater in Milliken?
Yes, with conditions. Milliken asks homeowners doing their own plumbing for a notarized Homeowners Affidavit, attesting that they live in the home, and anyone paid for plumbing work must hold a Colorado license. Colorado’s State Plumbing Board adds that the home can’t be for sale, resale, a flip or a rental, the owner must do the work personally, and the permit and inspection still apply.
The state also warns that homeowner’s insurance may not cover damage caused by anyone working without liability insurance. Licensed plumbers do our Milliken work, and liability insurance covers every job.
Milliken homes: an early-2000s core and a newer wave
The Census Bureau estimates Milliken grew from 8,377 residents in 2020 to 9,183 on July 1, 2025. ACS 2020-2024 5-year estimates count 3,310 homes with a median year built of 2004 (±4 years); 28.5% were built in 2010 or later and 12.9% before 1980.
A heater original to a 2004 home would be about 22 years old, well past the 10 to 15 years DOE gives most storage water heaters, so check its label date. Homes from the 2010s are now entering that window.
On a replacement, Colorado’s plumbing code waives its newer rule to pipe relief valve discharge to a drain or outdoors. An expansion tank is still needed where a pressure-reducing valve, check valve or backflow device traps expanding water.
Is 4,752 feet high enough to need an altitude setting?
Yes. Milliken’s USGS reference point is 4,752 feet, more than 2,700 feet above the 2,000-foot line in IFGC 402.2, the fuel gas code section requiring gas flow to be adjusted for altitude.
Rinnai’s V-series tankless units use altitude level 1 (2,001-5,200 ft) here, and one 199,000 Btu/h natural gas model derates to 170,000 Btu/h. Milliken is well under the 5,400 feet where a natural gas Navien NPE-2 needs its high-altitude kit, but the installer still selects the unit’s altitude range in its menu. Tank heaters follow their own manuals, which must come with the Counter Permit anyway.
Gas, power and water in Milliken
The Town of Milliken lists Xcel Energy for natural gas and electricity across most of Milliken, with Poudre Valley REA supplying electricity in the Mad Russian and Mill Iron areas. Water comes from two town wells plus purchases from Greeley and the Central Weld County Water District, and the Town’s 2026 report packet gives no hardness figure for Milliken’s own system.
