Allegheny County dye tests and point-of-sale sewer inspections

A dye test is a municipal inspection that confirms your storm water and your sanitary sewage are going where they are supposed to go, and not into each other. A technician introduces colored dye into your downspouts, area drains, and sanitary fixtures, then watches where it comes out at the municipal connection.

The reason municipalities care is straightforward. Storm water leaking into a sanitary sewer overwhelms the treatment plant during heavy rain, which is a well-documented problem across the Pittsburgh region. Sanitary waste crossed into a storm sewer goes straight into the rivers. Neither is acceptable, so most municipalities in and around Allegheny County require the test at the point of sale, before a property changes hands.

Who needs one, and when

• Sellers. Most local municipalities require a passing dye test before transfer. This is usually the trigger, and it usually surfaces later in the process than anyone wants.
• Buyers. Worth pairing with a sewer camera inspection during your inspection contingency, especially on a home built before 1970. A dye test tells you the connections are legal. A camera tells you the pipe is sound. They answer different questions.
• Owners doing work. Some municipalities require testing after certain sewer, downspout, or drainage work, or as a condition of a permit.
• Anyone with a compliance letter. If you have received notice from your municipality or water authority about lateral compliance or storm water separation, bring it to the phone call and we will read it with you.

Requirements vary by municipality, and they change. Before we come out we confirm what your specific municipality requires and what report format they accept, so you are not paying for the wrong test.

What happens during the test

1. We confirm the requirement first. Which test, which forms, which report format, which municipal office receives it.
2. We locate your connections. Downspouts, area and yard drains, foundation drains, and the sanitary line, plus the municipal sewer and storm connections at the street.
3. We introduce dye. Colored dye and water into each drain point, one at a time so results are attributable to a specific drain.
4. We observe the outfall. Watching the sanitary and storm connections to see which one the dye shows up in.
5. We document. Photos, notes on each connection, and the result for each drain point.
6. We file the report. In the format your municipality requires, submitted to the right office.
7. If it fails, we walk you through the fix with pricing, on the same visit where possible.

What a failed dye test actually means

A failure is a connection problem, not usually a catastrophe. The common findings:

• Downspouts tied into the sanitary sewer. Extremely common in older Pittsburgh homes, because it was normal practice when they were built. The fix is separating them and rerouting the storm water.
• A failed or collapsed rain leader. The underground pipe carrying downspout water away from the foundation has broken, and the water is finding the sanitary line. Fix is replacing the rain leader with proper-pitch PVC.
• Foundation or area drains cross-connected to sanitary.
• A cracked or offset lateral letting storm water infiltrate. This is where a dye test turns into a camera inspection, because now you are looking at the condition of the pipe itself.
• Sanitary crossed into storm. Less common, more serious, and municipalities treat it urgently.

Worth knowing: in many local municipalities, including the City of Pittsburgh, the property owner is responsible for the sewer lateral all the way from the house to the municipal main. Not just to the property line. That surprises a lot of sellers, and it is the reason a failed test sometimes carries a real repair number.

When it fails in the middle of a closing

This is the situation we get called into most. The test failed, the closing date is set, and everybody is looking for a contractor who can move.

• We do this work every week and we know how the local municipal offices want the paperwork.
• We pull permits in the townships we serve and coordinate the inspection directly with the inspector.
• We can quote the repair on the same visit as the failed test in most cases.
• We have crews, an excavator, and a concrete and restoration team in-house, so we are not waiting on three subcontractors to line up their schedules. Restoration is part of the job, not a separate call.
• If the repair genuinely cannot be finished before your date, we will say so early rather than let you find out the week of.

We also talk with your agent or attorney directly if the transaction needs it. Say the word and we will keep them copied.

Pair it with a camera inspection

A dye test and a camera inspection answer two different questions, and doing both in one visit is usually the better buy:

• The dye test tells you whether the connections are legal and separated. It is a compliance answer.
• The camera tells you whether the pipe is cracked, root-filled, bellied, offset, or made of failing Orangeburg. It is a condition answer, and it is the one that carries a five-figure number if it goes badly.

For a buyer doing due diligence on an older home, we recommend both. See what a camera inspection includes.

Pricing

We present exact pricing on the call when you schedule, once we know which municipality you are in and what they require. Tiers below show relative investment, not real numbers.

• Standard dye test with municipality-formatted report: entry tier ($). Adjusts with the number of drain access points.
• Combined dye test and camera inspection: entry tier ($), and the better value on an older home.
• Re-test after a repair: entry tier ($), and often reduced when we did the repair.
• Repairs on a failed test are quoted separately and depend entirely on what failed, from a downspout separation to a full lateral replacement.

Financing is available on repair work, which matters when a failure lands unexpectedly in the middle of a sale.

What is included

• Confirmation of your municipality’s specific requirement before we come out.
• Dye testing of all accessible drain points, tested individually.
• Photo documentation and per-drain results.
• Report in the format your municipality accepts, filed with the right office.
• On-site walkthrough of the findings with the technician.
• Quote for any required repair, with no obligation.
• Direct communication with your agent or attorney if the transaction needs it.
