How do I know if my Henderson house is on a septic tank or a district sewer?

Check whether you get a sewer bill from a district. If you do not, look for a buried tank lid or a cleanout in the yard, and ask Adams County. The difference matters when a drain backs up: it can be a blocked line or a full tank. Stop running water and tell us which you have when you call.

The water pressure has dropped in my older Henderson house. Are the pipes the problem?

If every fixture is weak and the first water of the morning runs brown, old galvanized steel pipe is a likely cause. Rust builds up inside and narrows the pipe. If only one faucet is weak, the aerator or a valve is more likely. Replacing a rusted supply line is a water line repair job.

My drains are slow and there are big trees near my yard. Could it be roots?

Yes. Roots enter at joints in older clay lines and catch grease and paper. On a larger lot the line to the main is long, and there is more pipe for roots to find. We run a camera through the line before recommending digging.

Henderson is an unincorporated community in Adams County, with no city utility of its own. Housing ranges from older homes near Brighton Road and 120th Avenue to newer neighborhoods such as Belle Creek. Water and sewer service depends on the address. Some homes connect to a water and sanitation district, and acreage in unincorporated Adams County may have its own well or septic tank. Check your bill first, because a backup in a district sewer and a backup in a septic tank are different problems.

What you see is usually one of three things. Drains that back up or gurgle, most often in the lowest fixture, point at the sewer line between the house and the main or tank, and on larger parcels that run can be long. Low pressure and brown water on the first draw in an older house can be old galvanized supply pipe rusting shut from the inside. A water heater that leaks or has no hot water is a tank, element or thermostat problem. Stop running water when a drain backs up. If you have a septic tank, tell us when you call.

A hard cold snap can split copper or PEX in an unheated crawl space, a garage or an outdoor hose bib. Shut the main, open a low faucet to drain the lines, and leave the area open. Related pages: sewer line repair, drain cleaning, and water line repair.

We run a camera through the sewer line before recommending digging, and we 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 Henderson · Local Notes

•Henderson is an unincorporated community in Adams County (ZIP 80640). Parts of the surrounding area have been annexed by Commerce City, Brighton and Thornton, so which utility serves a home depends on the address.
•South Adams County Water and Sanitation District runs its Williams Monaco Wastewater Treatment Plant at 9702 Monaco Street in Henderson. Where water comes from that district, its 2021 water quality report gave typical hardness as 22 grains per gallon for 2020, and the district began softening treatment in 2021.
•The district says sewer backups can come from grease, wipes flushed down toilets, and roots growing near or over sewer service lines.
•Belle Creek Metropolitan District exists to fund neighborhood infrastructure including streets, water and sewer, so newer Henderson neighborhoods differ from older parcels along Brighton Road.
