What Is Hydro Jetting and Is It Safe for Older Pipes?
Hydro jetting is a pipe cleaning method that propels water at pressures of 3,000 to 8,000 PSI through a specialized nozzle restoring full-diameter flow throughout the entire line rather than simply punching a hole through the clog. It is safe for older pipes provided the pipe is structurally sound — the critical first step is always a CCTV camera inspection to confirm there are no pre-existing cracks, joint separations, or pipe wall deterioration before jetting begins. Clay tile, cast iron, PVC, and concrete sewer pipe in good condition all tolerate hydro jetting well. Pipes with active fractures, significant corrosion, or compromised joints should be repaired or relined before jetting, as the pressure would worsen existing damage. Delta performs camera inspection prior to all hydro jetting work across Salt Lake, Davis, Utah, Summit, and Washington Counties to ensure safe, effective results every time.
When Does a Sewer Line Need Hydro Jetting vs. Snaking?
Snaking — also called rodding or augering — uses a rotating mechanical cable to punch through a clog and restore minimal flow. It is the right tool for isolated, soft blockages near an access point and is fast and inexpensive for simple stoppages. Hydro jetting is the right tool when snaking has not held, when the buildup is coating the pipe walls rather than forming a discrete plug, when the line has recurring clogs indicating systemic grease or scale accumulation, when tree root intrusion is confirmed by camera, or when the line needs to be fully cleaned before a trenchless lining or pipe rehabilitation project. The key practical distinction: snaking creates a hole through the obstruction; hydro jetting removes it entirely and cleans the pipe wall surface. For commercial kitchens, municipal mains, and large-diameter sewer lines where FOG and sediment accumulate continuously, hydro jetting is the standard maintenance method — snaking provides only temporary relief.
How Often Should Municipal or Commercial Sewer Lines Be Hydro Jetted?
Service frequency depends on line diameter, usage load, and what the pipe carries. For commercial kitchens and restaurants, hydro jetting every 6 to 12 months is the industry standard — FOG (fats, oils, and grease) accumulates continuously and is the leading cause of sewer overflows in commercial food service settings. Multi-tenant commercial buildings and retail centers typically benefit from annual jetting of main lines and high-use laterals. Municipal sewer mains on preventive maintenance programs are often jetted on a 3- to 5-year cycle depending on pipe age, diameter, and flow data from CCTV inspections. Lines with confirmed tree root intrusion require more frequent service — typically annually — because roots regrow after jetting and must be cleared before they reach a blocking mass. For any facility in Utah operating under a pretreatment permit, regular documented jetting service supports compliance with local sewer use ordinances and provides evidence of due diligence during municipal inspections.
Can Hydro Jetting Remove Tree Roots from Pipes?
Yes — hydro jetting is one of the most effective methods for removing tree root intrusion from sewer lines, particularly for fibrous root masses and smaller root strands that have grown through pipe joints or cracks. The high-pressure forward jet cuts through root material and the rear-facing jets flush the debris downstream and out of the line. However, hydro jetting addresses the symptom, not the source: roots regrow toward moisture and will re-enter the pipe through the same breach unless the pipe is repaired or relined. A CCTV camera inspection before jetting is essential to confirm root size and density — extremely thick root masses may require mechanical root cutting before jetting can be effective, and severely infiltrated pipes may need relining or replacement rather than continued clearing. After jetting, a follow-up camera pass documents the cleaned condition and identifies any joint or pipe wall damage the roots have caused, informing the right long-term repair strategy.
Hydro jetting is a pipe and drain cleaning method that uses very high‑pressure water to clear clogs and buildup from the inside of plumbing and sewer lines.
A specialized machine pressurizes water (often up to several thousand PSI) and sends it through a hose with a jetting nozzle inserted into the pipe. The nozzle sprays water forward to break through blockages and backward to pull the hose along and scour the pipe walls. This process removes grease, roots, scale, and other debris, restoring the pipe’s internal diameter and improving flow without using harsh chemicals.
