Signs to watch for: Domestic Drain Jetting
- ✓ A drain blocks again every few months
- ✓ Several fixtures drain slowly
- ✓ Grease builds up in a kitchen waste pipe
- ✓ A gully holds silt or grit after rain
- ✓ A smell returns soon after the drain was cleared
Home drains collect grease, scale and silt over the years, while the pipe slowly narrows. A jetting hose sends high-pressure water along the pipe through a gully or manhole. The jets break up the build-up and push it out. This cleans the pipe walls as well as clearing a block.
The engineer looks at the access points. A camera check shows whether the pipe can take high pressure, since high pressure can harm weak pipes. A weak pipe may need a gentler method.
The hose goes into the drain through the best access point. The nozzle and pressure suit the pipe type, because each material takes a different load. Ask the engineer to start at a low setting.
The nozzle moves along the pipe and scours the walls. Meanwhile, loose debris flows towards the access point. Hard build-up may need a second pass.
Running water shows whether the flow has returned. A second camera look can show the result. Ask for the footage if you want a record.
MyJobQuote gives £70 to £175 for jetting. HomeServe gives an average of £259 for water jetting of external drains. The two guides differ, so quote each by name. These are typical UK ranges, not York quotes, since prices vary by site. Ask for a written quote before work starts, and ask whether there is a call-out charge.
It is safe for sound pipes when the pressure suits them. High pressure can harm cracked or weak pipes. Ask the engineer to check the pipe first, since a camera look shows its state.
There is no single rule, because homes differ. Drains near big trees, or with a history of grease, may need more care. Ask the engineer what suits your pipes after a camera check.
No. The hose goes in through existing access points such as gullies and manholes. Digging only follows if the camera finds damage. In that case, ask for a written quote for the repair.
Each has its place. Rods push through a block in a straight run, while a jet also cleans the pipe walls. Ask the engineer why they chose one, since the cause of the block decides it.
A jet can cut small roots and wash them out. Roots tend to grow back, however, if the pipe still has a gap. A camera shows where they got in, and a repair closes the gap.
