Where a drain here keeps blocking, jetting is usually the answer — and on modern pipe it is a straightforward maintenance job.
Sand and long runs
Beach sand settles along the bottom of a line and stays put, and large homes mean long runs with gentle falls where it accumulates. A cable makes a channel through it; jetting flushes it out.
Grease from a full house
A kitchen that does nothing for weeks and then caters for ten people over a holiday weekend puts a great deal down the line in a short space of time. That is the pattern behind most recurring kitchen drain problems here.
Safe on modern pipe
One advantage of newer housing — PVC in good condition handles jetting comfortably. The caution we give owners of century-old cast iron simply does not apply on this island.
Best scheduled between visits
For a seasonally used home, jetting before the season means the line starts clear rather than being dealt with while the house is full.
