All Drains Slow in House

When every drain in the house seems slower than normal, the pattern matters. This is one of the strongest clues that the issue may be in the main sewer line.

Common causes we see

  • Main line clog affecting the whole drainage system
  • Roots or pipe damage downstream from several fixtures
  • Standing water in a low spot or belly
  • Heavy buildup inside an older line

These are exactly the kinds of issues a sewer camera inspection is designed to document before you pay for major work.

Why you should not ignore it

  • Whole-house symptoms usually get worse, not better, without diagnosis
  • If lower-level drains are affected, backup risk is higher
  • The right answer could be cleaning, repair, or monitoring—but only if you know the cause

How GroundTruth helps

GroundTruth documents the true condition with sewer camera inspection. If the line is intact but dirty, hydro jetting may be the next step to clear it more completely and restore flow.

We are inspection-only. That means no repair sales pressure tied to the diagnosis. You get video + written documentation and can use the findings with the contractor of your choice.

Best next step

If this sounds like what you are seeing at your property, the smartest move is to document the line before the next rain event, laundry day, or backup makes the decision for you.

Why every fixture can be affected

A whole-house slow drain pattern usually means water is struggling to move through the shared line leaving the home. That can happen because of heavy buildup, roots, standing water, or another restriction farther downstream.

GroundTruth provides independent inspection-first documentation so you can decide whether monitoring, cleaning, or repair is the right next step.
