Drainage blockage repair and drain line correction
Clear blocked drains, fix bad slopes and broken lines, and stop sewer smells for good.
Blocked drains, water backing up into the bathroom and sewer smells are unpleasant and unhealthy. Clearing the blockage helps for a while, but if the line is badly sloped or broken, it returns.
RennovEN clears the blockage, then finds out why it formed — slope, broken pipe, roots or missing traps — and corrects it.
Signs you need this
- Water draining slowly or backing up
- Gurgling sounds from drains
- Sewer smell in bathrooms

Diagnosis
Why it happens
Flat or reverse slopes
Drains without enough fall collect sludge.
Broken lines
Cracked pipes let soil in and roots grow inside.
Dry or missing traps
Without water seals, sewer gas enters rooms.
