Blocked Drains in Daventry

Daventry's newer estates — Middlemore and Monksmoor — run on modern plastic drainage that rarely blocks without a specific cause, usually fat, wipes, or a builder's offcut left in the run during construction. The older streets around Bowen Square and the town centre sit on original clay drainage, which is more prone to root intrusion from mature street trees and gradual scale buildup over time.

High-Pressure Jetting

For blockages that rodding can't clear — deep scale, compacted debris, or extensive grease buildup — we use high-pressure water jetting. A flexible hose feeds a rotating nozzle through the drain, blasting water at up to around 3,000–4,000 psi to strip the pipe wall clean rather than just punching a hole through the blockage.

We use cold water for general blockages and switch to hot water where fat and grease have hardened onto the pipe wall — heat helps melt the buildup as the jet clears it, rather than just displacing it further down the run.

Root Cutting

Tree roots find their way into drains through hairline cracks or displaced joints, then grow into a dense mat that traps debris and causes recurring blockages. We fit a rotary root-cutting head to the jetting hose to shred the roots and restore flow. If root intrusion keeps recurring at the same point, we'll usually recommend a CCTV drain survey to check whether the underlying joint needs repair.

Frequently Asked Questions

Do you use high-pressure jetting in Daventry?
Yes. High-pressure jetting uses a flexible hose and rotating nozzle to blast water at up to around 3,000–4,000 psi through the drain, cutting through grease, scale, and debris that rodding can't shift. We use cold water for general blockages and hot water where fat and grease buildup needs melting as well as blasting.
Can jetting clear tree root intrusion?
Yes, with a root-cutting attachment. A rotary root-cutting head fitted to the jetting hose shreds roots that have grown into the pipe through a cracked joint, restoring flow. For persistent root intrusion, we may recommend a CCTV survey afterwards to check whether the joint itself needs repair.
How quickly can you clear a blocked drain in Daventry?
We attend Daventry call-outs promptly, with urgent jobs prioritised. Most standard blockages — toilets, sinks, and accessible outdoor drains — are cleared within an hour of arrival.
Do you jet drains on the newer Middlemore and Monksmoor estates?
Yes. Modern plastic drainage still blocks — usually fat, wipes, or construction debris — and clears quickly with jetting since there's rarely root intrusion to deal with on newer runs.
What causes blocked drains in Daventry's older streets?
Around Bowen Square and the town centre, the most common causes are root intrusion into original clay drainage and gradual scale or silt buildup in older, shallower-graded runs.
