water dropPreventive Maintenance Programs

sticky noteWe developed our preventive maintenance progam to assist our customers with high volume or troublesome lines and the inconvenience and embarrassment of frequent blockages, unpleasant odors, or health hazards. The Dennis Diffley Drain preventative maintenance program is a cost effective method of ensuring that your drains remain open and functional so they are ready when you need them.
What is it?
The program is specifically designed to meet your individual requirements and offers regularly scheduled maintenance of your drains, sewers and associated sewer pipe work.
The idea is to keep the system flowing freely, thereby avoiding the problems associated with blockages and reduced flow. It can be applied to any drainage system where regular maintenance is warranted. All pipe work is different, and the frequency and type of service depends on the amount of use the system gets. The substance being discharged, size of building and type and size of pipe work are all contributing factors to the effectiveness of the system.

The first step is to contact us to make an appointment so that we can come out to assess your particular situation. Then we will analyse previous problems and isolate areas of concern. We will then recommend an initial ‘clean’ that will return the pipe work to full flow and optimum performance. A preventative maintenance program is then prepared showing which part of the system needs cleaning on a regular basis. Then, by prior arrangement and at a time to suit you, or trained technicians will carry out the scheduled work, ensuring a minimum of inconvenience.

The Benefits? maintenance02
A pre-scheduled preventative maintenance program helps to avoid blockages that can result in damage to property and inventory, and the potential health risk from flooding, the obvious inconveniences and, of course, unbudgeted expenditures.
Entering into a scheduled preventative maintenace program ensures that your sewer and drain lines will be regularly serviced so that you can avoid the serious problems associated with back ups, over flows and blocked drainage systems.


What’s the next step?
Call us right now while it is fresh on your mind to set up an appointment without obligation, so that we can assess our situation or if you require immediate attention we can do that also and as always we will handle your call promptly and courteously.
