Domestic drain jetting uses high-pressure water to clean the pipes of a home. A hose with a rotating nozzle scours grease, scale and silt off the walls, then flushes the debris away. Jetting can suit most common pipe materials, as long as the pressure suits the pipe.
Jetting works differently from chemicals. Chemicals dissolve a channel. Jets, however, clean the whole pipe wall. The method also uses only water, which many homeowners prefer.
People use jetting to clear a block, and also to keep drains clean after one. The wider drain jetting guide covers the basics. If you run a business, read about commercial drain jetting instead.
A good engineer looks at the pipe first, since weak or cracked pipes may not take high pressure. A short camera look can settle the question. A quick look can save a costly mistake.
The hose goes in through a manhole, gully or clean-out point. The engineer picks a nozzle and a pressure to suit the pipe. Matching the nozzle to the pipe protects older drains.
The nozzle moves along the pipe, while the jets scour the walls and push debris downstream. Working from the problem back towards the access point helps. Debris moves downstream, so the engineer checks the next chamber.
Running water shows whether the flow has returned. A camera can then show the clean pipe, if you ask for that. A final camera look is optional, so ask about it up front.
Use these questions to compare quotes, since the answers differ from one engineer to the next. Write the answers down, since a written note helps if the job changes. Then compare two quotes if the job looks large.
These are typical UK ranges from national guides, not Essex quotes. MyJobQuote lists jetting at £70 to £175. HomeServe gives an average of about £259 for water jetting of external drains.
The price moves with pipe length and build-up. Ask for a written quote before work starts, and ask whether there is a call-out charge. A camera survey can add to the cost, yet it shows what the jets achieved.
It can be, when a careful engineer matches the pressure to the pipe. Cracked or weak pipes may not take high pressure. Ask for a pipe check first.
No single rule fits every home. Drains near big trees, or with a history of grease, may need it sooner. Ask the engineer what they found and when to repeat the clean.
No. The hose goes in through existing access points. Nothing needs digging. The unit may stand on the drive or lawn, so ask about protection.
