Backflow and sillcock repair in Tollgate Crossing, Aurora, CO 80016
Tollgate Crossing is a 2010s neighborhood of two-story homes and townhomes in southeast Aurora. The indoor plumbing is still young, so most of our calls here start outside, at the hose bibs, the sprinkler backflow assembly and the main pressure valve.

Yes. Tollgate Crossing, around S Biloxi Way and E Bellewood Dr, is part of our regular southeast Aurora route by I-225 or E-470. We answer 24/7. A split spigot or a backflow leak gets a same-day visit when we can reach you, and spring backflow testing is scheduled ahead so the sprinklers are ready when the season starts.
What the outside of a Tollgate Crossing home asks of its plumbing
Tollgate Crossing filled in during the 2010s with two-story single-family homes and a set of townhomes, laid out around lakes and trails inside the community. A house from that decade usually has PEX supply lines, plastic drains, a frost-free sillcock or two and an irrigation system with its own backflow assembly. Those outdoor parts take the brunt of southeast Aurora weather, which is why they fill most of our calendar here.
Arctic fronts can arrive quickly, with temperatures dropping well below zero in a matter of hours. A frost-free sillcock only protects itself when the hose is off, because a connected hose traps water in the valve body inside the wall. Backflow assemblies sit above ground beside the house, so a cold night can crack the brass body or a test cock if the system was not drained. Aurora Water requires those assemblies to be tested at least once a year.
Inside, a newer home often has a pressure reducing valve on the main line and an expansion tank at the water heater. When either one wears out, pressure climbs, toilets refill on their own, and faucets start to drip. Townhome owners should also know where their own shutoff sits, since a leak in a shared wall can reach the unit next door before anyone notices.

Backflow Testing & Repair
Sprinkler backflow assemblies here need a yearly test, and spring start-up is when most owners schedule it. Cracked bodies after a hard freeze are the usual repair we make.

A hose left on through a cold night can split a frost-free sillcock inside the wall. The leak often shows up only in spring, when the spigot is first turned on.

When the valve on the main line wears out, house pressure creeps up. Banging pipes, running toilets and a dripping relief valve at the heater are common signs.
More on pressure reducing valvesExpansion Tank Installation
The small tank above the water heater absorbs pressure as water heats. Once its bladder fails, the heater relief valve may weep and fixtures take extra strain.

In attached townhomes, a slow leak inside a shared wall can travel before it shows. We trace the source with moisture meters and thermal imaging before opening drywall.

Seasonal habits for a Tollgate Crossing yard and utility room

- Pull every hose in OctoberDisconnect garden hoses before the first hard freeze. Without a hose attached, a frost-free sillcock can drain properly and survive a sudden cold front.
- Blow out the sprinklers on timeDrain the irrigation lines and the backflow assembly before winter. Water left inside the brass body is what cracks it on the first deep freeze.
- Test pressure with a gaugeA hose bib gauge costs little at a hardware store. Readings well above normal household pressure mean the pressure valve needs a look.

Questions
Plumbing questions from Tollgate Crossing
Why does my Tollgate Crossing spigot leak inside the wall only in spring?
A hose left on over winter traps water in the frost-free valve, and a cold snap splits the long stem inside the wall. The crack stays hidden until you turn the spigot on in spring and water runs into the basement or wall cavity. We replace the sillcock and check for water damage nearby.
Who tests the sprinkler backflow assembly at a Tollgate Crossing home?
Aurora Water requires backflow assemblies to be tested at least once a year by a qualified cross-connection control tester, with results sent to the city. Spring start-up is when most owners schedule it. We can repair or replace a failed or freeze-cracked assembly and get your irrigation running again.
How do I find the shutoff for my Tollgate Crossing townhome?
Most townhomes have a main valve inside the unit, often in a utility closet, basement or near the water heater. Some also have a curb or exterior shutoff. Find yours before you need it. If the valve is stiff or missing a handle, we can replace it so you can stop a leak quickly.
