What are the signs my NB irrigation system needs professional repair?

Your New Brunswick irrigation system needs professional repair when you notice consistently dry or flooded zones, a sudden spike in your water bill, visible water pooling when the system runs, or sprinkler heads that fail to pop up or retract properly. While minor adjustments like cleaning clogged nozzles are DIY-friendly, several issues require a technician's expertise and specialized equipment.

Uneven coverage within a single zone is one of the most common signs of a problem. If some heads in a zone spray weakly while others have full pressure, you likely have a cracked pipe or fitting underground that is leaking water before it reaches the farther heads. In New Brunswick, this is frequently caused by frost damage from inadequate winterization — even one missed season of blowout can crack PVC fittings and poly pipe connections that sat with residual water through NB's -25°C to -35°C winters. Underground leaks often show up as unusually soft or muddy areas in your lawn when the system runs.

Sprinkler heads that do not fully pop up, stay up after the zone shuts off, or spray erratically indicate either worn internal seals, debris in the mechanism, or insufficient pressure reaching the head. NB's sandy coastal soils and gritty clay soils inland introduce sediment into the system, gradually wearing out seals and clogging nozzles. A head that stays up after the zone shuts off usually has a worn spring or debris preventing retraction — a relatively inexpensive repair at $15-30 per head installed.

A zone that runs but produces no water from any head typically means a failed solenoid valve (the electric valve that controls each zone). NB's freeze-thaw cycles put enormous stress on valve components, and solenoid failures are common in systems over 5-8 years old. Valve replacement costs $75-200 per valve including labour. If your controller appears to be sending signals but nothing happens, the wiring between the controller and valves may have been damaged by frost heaving or digging — a professional can test this with a multimeter and trace the wire path.

Water pressure changes across the whole system — either a noticeable drop or increase — warrant professional assessment. Pressure drops may indicate a main line leak, a failing pressure regulator, or a problem with your water supply. Pressure increases (heads misting rather than spraying) can damage components and suggest a failed pressure-reducing valve. NB homes on well water should also check for reduced well capacity during dry summer periods, which can starve an irrigation system.

Professional irrigation repair in New Brunswick typically costs $150-400 depending on the complexity of the issue. Most straightforward repairs (valve replacement, head replacement, minor pipe repair) can be completed in a single visit. For buried pipe leaks, technicians use listening devices and pressure testing to locate the break without unnecessary digging. If your system is over 15 years old and requiring frequent repairs, a full system assessment may reveal that targeted upgrades are more cost-effective than continued patchwork repairs.
