The city is old enough to have a historic core and big enough to have every housing era since. Matching the fix to the house matters here.

The older core around downtown

The West Side Historic District and the blocks closest to downtown hold Longmont's oldest houses. Plumbing in these homes has usually been patched by several owners, so it pays to look at materials before symptoms.

  • Galvanized steel supply pipe rusts from the inside. Pressure drops at one fixture, then several, and the first water out of a tap may be tinted.
  • Cast iron drain stacks crack along the bottom where water runs, often out of sight in a wall or under a slab.
  • Clay tile sewer laterals let roots in at the joints, which makes the basement drain the first to back up.

Old isn't the same as failing. A camera on the sewer line and a look at the supply piping tell you if you face one pipe repair or a longer plan.

Prospect New Town, begun in 1996, and other newer subdivisions rarely show up in the second row, since their sewer laterals are plastic rather than clay. Their trouble tends to be in fixtures, water heaters and supply fittings.

Basements, the St. Vrain and sewer backups

Groundwater seeps in through walls and slabs. A sewer backup comes up through the floor drain, the basement toilet or the lowest shower, and it smells like what it is. If you have had a backup, or bought a house that did, have the lateral camera-inspected; silt, debris and root growth can all reduce its capacity. Keep the floor drain trap filled with water so sewer gas stays out, and know where your cleanout is so a sewer line technician can reach it quickly.

Repair or replace a water heater: four questions

  1. Is the tank itself leaking? If water is coming from the tank body, replace it. Leaks from fittings or the relief valve line are repairable.
  2. Is the failure a part? Igniters, thermocouples, gas valves, elements and thermostats can all be replaced.
  3. How old is it? The manufacture date is coded in the serial number on the label. An old tank that needs an expensive part is usually a replacement candidate rather than a repair.
  4. Is it keeping up? If the household has outgrown it, or showers run cold before the second person is done, repair won't fix that.

Replacement in Colorado requires a permit and inspection by the local building authority, and that includes same-spot swaps. See water heater service for more.

FAQ

Plumbing questions from Longmont

Where does Longmont's tap water come from?

The City of Longmont uses two watersheds: the St. Vrain Creek basin, including Ralph Price Reservoir in Button Rock Preserve, and Colorado River water delivered through the Colorado-Big Thompson Project. The share from each changes year to year with snowpack and operations. The annual water quality report lists the split and the test results, including hardness.

Why is water pressure low in my older Longmont house?

In older homes the usual cause is galvanized steel supply pipe that has rusted and narrowed inside. The drop often starts at one fixture and spreads. Clogged aerators and a partly closed shutoff valve are easier fixes worth ruling out first. If the pipe is the problem, replacing the worst runs or repiping restores pressure.

Should I get a sewer inspection before buying a house in Longmont?

For an older home, yes. A camera inspection of the sewer lateral shows roots, cracks, offset joints and low spots that a standard home inspection doesn't cover. Clay tile laterals are common in older neighborhoods, and a repair found after closing is yours to pay for. For a newer home with plastic pipe, it is less critical.
