Marquis Hot Tub Case Study
Their Sewer Line Was a Ticking Time Bomb. Here’s How We Kept Them Open for $600 a Month.
A sewer belly buried under a concrete slab. A repair bill that could easily hit $50,000. A property manager without the budget. Here’s what we did instead and why it’s working.

A Camera Inspection Revealed Something the Owner Never Saw Coming
When Marquis Hot Tub started experiencing recurring plumbing slowdowns at their Beaverton storefront, they called us in. We ran a camera inspection down the sewer line and found the culprit: significant bellies multiple sags in the pipe buried deep under a concrete slab.
This wasn’t a simple clog. This was a structural problem. And because the line runs interior, underneath concrete, fixing it properly isn’t a weekend project.
“This is the exact situation where doing nothing costs the most. Standing sewage doesn’t wait for budget cycles.”
What Is a Sewer Belly?
A sewer belly is a sag or low spot in an underground pipe. Instead of gravity pulling waste smoothly down the line, this dip creates a permanent pool of standing water and debris. Over time, that pool fills and eventually, everything backs up.
Signs Your Property Might Have the Same Problem
Frequent Toilet Backups
Toilets that back up regularly even after being snaked are a red flag that the problem is deeper in the line, not at the fixture.
Slow Drains Everywhere
When multiple drains in the building are slow at the same time, the issue is almost never at the sink. It’s downstream.
Foul Odors From Drains
Standing sewage in a belly ferments. If your drains smell even when nothing is clogged, that’s waste sitting somewhere it shouldn’t be.
Clogs That Keep Coming Back
If you’re calling a plumber every few months for the same problem, jetting is clearing the symptom, not the cause. Time for a camera inspection.
What Happens When You Ignore a Sewer Belly
Ignoring it isn’t a neutral choice. Here’s what the timeline actually looks like.
- 01Facility-wide slowdownsFirst the toilets get sluggish. Then the sinks. Then customers notice. Then you’re having conversations you don’t want to have.
- 02Accelerated pipe deteriorationStanding waste is corrosive. The longer it sits, the more it eats through the pipe walls turning a sag into a crack, and a crack into a collapse.
- 03Raw sewage backupsWhen the belly finally fills, waste doesn’t just stop flowing it reverses. Raw sewage on your floors. Into your walls. Into your product.
- 04Complete pipe collapseA corroded belly under a concrete slab doesn’t give you warning signs. It fails. And then you’re not calling for a repair you’re calling your insurance company.
- 05Health code violationsSewage exposure triggers mandatory health inspections. In a retail environment, that means forced closure on someone else’s timeline.
- 06Emergency costs that dwarf the repairEmergency call-out, water mitigation, biohazard remediation, and forced downtime can cost multiples of what a planned replacement would have.
Here’s Where the Numbers Get Interesting
Every property manager facing this situation has three options. Here’s the honest breakdown of what each one actually costs.
Ignore It
$100K+ Potential lossesEmergency remediation, raw sewage damage, forced business closure, health code violations, and a pipe replacement still waiting at the end of all of it. There is no savings here only delay.
Strategic Monthly Jetting
$600 Per visit · MonthlyWe hydro jet the line monthly and follow every session with a camera inspection to confirm it’s clean. Debris is cleared before it ever has the chance to block. The business stays operational while the property manager saves toward the real fix on their own timeline.
Full Line Replacement
$50K Estimated · Interior slab workThe right long-term answer. Interior sewer lines under concrete are complex access, depth, concrete removal, and reinstatement all drive up cost. For this job, the estimate leans toward the higher end of the $10K-$50K range. This is the destination. Option B buys the time to get there.
Monthly Jetting + Camera Verification: How the Plan Works
This isn’t a set-it-and-forget-it approach. Every single visit follows the same protocol because the only way to know the line is actually clear is to look at it.
This Is a Bridge, Not a Cure
Monthly jetting is not a permanent fix. The belly is still there, and the pipe will eventually need to be replaced. What this plan does is eliminate the immediate danger, protect the business from unexpected shutdowns, and give the property manager a real runway to plan and budget for the right solution. We’d rather be honest with you now than called in for an emergency later.
