My sewer keeps backing up in my older Welby house. Is it tree roots or the pipe?

Often it is both. Roots enter where an old clay or cast iron lateral has an open joint, and a bellied section holds water and collects debris behind it. A camera run shows the joint, the belly or the break so the fix matches the fault. Stop using water until it clears, and call (720) 856-5811.

After heavy rain my basement near the South Platte has water in it. Is it the sump pump or a leak?

If the water shows up after rain and the pit is full, look at the pump, float and check valve first. If water keeps appearing in dry weather, a supply or drain leak is more likely. Keep away from standing water near outlets and appliances, and call (720) 856-5811 if you are not sure.

Our water comes out brown in the morning and pressure has dropped. Could it be the old pipes?

In a home built before the 1970s, corroding galvanized supply pipe is a common cause: rust flakes loosen when water sits overnight, and mineral build-up narrows the pipe and lowers pressure. Run the cold tap for a minute to see if it clears. If the whole street has the same problem, the cause may be the utility side. Call (720) 856-5811 to sort it out.

Welby is an unincorporated community in Adams County, south of 88th Avenue, east of I-25 and west of the South Platte River. It was farmland, known for vegetables, until the interstates arrived around 1960. Adams County's own community plan says the infrastructure here is aging, and that is what shows up inside the houses.

The common problems are a main line that backs up, a wet spot in the yard over the sewer lateral, rusty water in the morning, and a sump pit that fills faster than the pump can move it. The causes are usually roots at a joint in an old lateral, a bellied section that holds water, corroded galvanized supply pipe in a pre-1970s home, or a failed pump, float or check valve. Shut off the water at the main if a pipe is leaking, and stop using fixtures if drains are backing up. If a sump pit is overflowing, keep out of standing water near electrical outlets.

We run a camera through the sewer line before recommending digging, so you see the fault before you decide. From there the next page is usually sewer line repair for a damaged lateral, water leak repair for a leaking or corroded supply pipe, or sump pump repair for a pit that will not keep up.

Call when sewage is coming up a drain, when water will not stop after you shut the main, or when the basement is taking on water. We explain what we find and put a written scope and price in front of you to approve before work begins. Call (720) 856-5811, Monday to Saturday, 9am to 6pm.

Plumber in Welby · Local Notes

•Welby was laid out in 1909 and farmed until about 1960. Adams County's Welby community plan calls the infrastructure here aging, so original sewer and supply lines are a real possibility.
•Clear Creek and the South Platte River form Welby's southern and eastern edges, and the county manages them as floodplain. Homes near that corridor are more likely to see groundwater in the lowest level, which puts sump pumps to work.
•The North Washington Street Water and Sanitation District, on East 78th Avenue, buys finished water from the Denver Water Board. Denver Water describes its water as soft to moderately hard, with scale forming over two to five years. Which district serves you depends on your address, so check your bill.
•Welby is unincorporated and governed by Adams County, not the City of Thornton, even though it shares the 80229 ZIP code.
