Ruth Lewis

Fantastic work carried out on a tired shower room that was long over due a refit. Dan and the team were professional, friendly with excellent attention to detail nothing was too much trouble. We are thrilled with the final results!!!

Luke Taylor

We had our boiler serviced by gaswise for the last couple of years and the service has always been great. We had Jake come over this time and he went above and beyond by sorting out a loose tap that he noticed while servicing. It may seem like a small thing but goes to show how he goes above and beyond for his customers. Thanks for your help.

John Robinson

Very diligent company. Installation of two commercial boilers into a large church. Thorough site surveys carried out over three visits including specialist flue manufacturer and the boiler manufacturers. Well managed installation with excellent post installation hand over and follow up.

Alison Taylor

Jack initially came to service our boiler, he was friendly, professional and did a great job. We wanted our heating system flushed, so asked for a quote. This was sent the same day and our system was flushed through on the day we wanted, all ready for the winter months by Jack & Harry. Again a friendly professional manner, and our home left clean & tidy.

David Stemp

We just moved in to our new property on Friday, we reported the taps not working in the kitchen on Thursday, Ryan came around, identified the problem, and changed the taps. Great, professional service, Ryan was very friendly and professional. Thank you.

Jess Slater

Ryan completed a boiler replacement and a Landlords certificate for us on our rental property. He was friendly and efficient, and we really appreciate the effort he went to, to ensure we were happy with the installation and that we understood how to use it before he left. Thanks

Our Drain Jetting Process

Our expert team uses the latest equipment and proven methods to provide a thorough, reliable service. From the initial inspection to final testing and ongoing maintenance, we ensure your system runs smoothly and efficiently.

Initial Assessment

We begin by assessing the severity of the blockage and identifying any visible drainage issues affecting your property.

CCTV Inspection (If Required)

For recurring or more complex drainage problems, we may recommend a CCTV drain survey to locate the exact source of the obstruction or identify pipe damage.

High-Pressure Drain Jetting

Using specialist jetting equipment, we clear grease, debris, scale, roots, and other obstructions from the drainage system safely and efficiently.

System Flow Testing

Once the blockage has been removed, we test the drainage system to ensure water is flowing correctly and the issue has been fully resolved.

Where appropriate, we provide guidance on reducing the risk of future blockages and maintaining the long-term health of your drainage system.

FAQs

What is drain jetting?

Drain jetting is a professional drainage cleaning method that uses high-pressure water to remove blockages, grease, sludge, scale, and debris from pipework.

What problems usually require drain jetting?

Drain jetting is commonly used to clear common issues such as:

Fat, oil, and grease (FOG) build-up
Wet wipes and sanitary products
Scale, silt, and debris deposits
Tree root intrusion (following root cutting where required)
Soap scum and food waste accumulation
Leaves, mud, and outdoor drain debris
Slow-draining or recurring blocked drains
Foul odours caused by build-up within pipework

Is drain jetting safe for pipes?

When carried out by trained professionals using the correct equipment, drain jetting is safe for most modern drainage systems and is highly effective at restoring proper flow. By choosing DrainWise, we can ensure a safe and efficient process from start to finish.

Can you clear my outdoor drains?

Yes, we can clear blocked external drains, gullies, soakaways, and underground drainage systems for both domestic and commercial properties.

Do I need a CCTV drain survey?

Not always. However, for recurring blockages or suspected pipe damage, a CCTV drain survey can help identify the underlying issue accurately and quickly, allowing us to provide the most targeted repairs.

Can drain jetting remove tree roots?

In many cases, high-pressure jetting can help remove smaller root intrusions, although severe root damage may require additional repair work.

How quickly can you respond to an emergency?

Can you jet drains as a preventative measure, or only when blocked?

Regular jetting helps remove grease, scale, and debris before they cause serious issues, making it a smart option for homes and commercial premises that want to reduce the risk of future blockages.
