It is common for irrigation systems even after fall time blow-out for there to be leaks and breakage do too freezing, ground erosion, soil movement and incomplete water evacuation.
In most cases broken irrigation lines cause flooding inside a living space because of hydraulic pressure exerted against a building foundation wall or basement floor slab.
The best way to avoid water damage and building water intrusions as a result of irrigation systems is too charged lines and closely monitor them at the same time.
Broken waterlines in an irrigation system are easily identified at the time in which the system is reinstated in the spring simply buy inspecting all water distribution sprinkler heads and spray nozzles when irrigation systems are charged and running.
failure to do identify leaks can cause ground saturation which can result in water pooling and water tables becoming saturated. This saturation can cause hydraulic pressures resulting in water penetrating buildings foundations, finish systems and even direct water escapes on or close to building exteriors resulting in seepage into living spaces.
In some cases, fundamental design flaws in rudimentary irrigation system plumbing do not allow for proper drainage when fall blow outs are performed.
Irrigation lines that terminate beyond a fixture can result in water piling up at the end of the pipe. This type of design flaw commonly fails as the water freezes and expand breaking the pipe. The lack of a drain cap limits the ability to completely drain water from that section of the irrigation system.
A close inspected of your irrigation system once the system is charged in the spring is the best way to avoid water escapes. It is recommended to monitor the system for at least 24 hours as failures can occur after the systems is under pressure.
Another common problem is broken and/or compromised plumbing because of wildlife interference which can sometimes occur when rodents, grazing animals like dear, horses and cattle frequent the property. In the winter months these animals can seek water and chew through plumbing lines or sprinkler heads causing breakage.
