Signs you need domestic drain jetting help
- Drains run slowly even after a block is cleared
- A bad smell from drains that keeps returning
- Grease build-up in a kitchen drain
- Silt and leaves in an outside run
- The same block returns within weeks
Domestic Drain Jetting explained
Domestic drain jetting uses high-pressure water to clean the pipes at a home. It is a form of drain cleaning, because the jets scour grease, silt and scale from the pipe walls. It also clears blocks.
Jetting is most common when drains run slowly or smell, or when a block returns. Kitchen drains and old outside runs are the usual cases. Rods can clear a block but may still leave the film on the walls.
Jetting does not suit every pipe, since a cracked or fragile pipe can suffer under high pressure. Read the wider guide to drain jetting for the full picture. See CCTV drain surveys if you worry about the pipe condition.
Drain cleaning at home: what jetting removes
Drain cleaning removes the build-up that narrows a pipe. At home this is mostly grease from the kitchen, while the bathroom adds soap and hair and outside runs collect silt and leaves. Each kind of build-up makes the pipe a little narrower.
A jet cleans a whole run, where rods clear a path. Because of that, jetting suits slow drains and repeat blocks. For a single soft block, simpler tools may do the job.
How a job usually runs
- 1. Check the pipe first
Before anyone uses high pressure, ask the engineer to check the pipe condition. A cracked or weak pipe may need a gentler method, since high pressure can harm it. A camera can show this.
- 2. Set up at the access point
The hose feeds in through a manhole, a gully or a clean-out point. No digging is necessary, since the access points already exist. The unit stands near the access point.
- 3. Jet along the run
Water jets scour the pipe walls while the nozzle moves along. Debris flushes towards a collection point. The pressure should suit the pipe, so ask which setting the engineer plans to use.
- 4. Check the flow
Running water afterwards shows if the drain flows freely. A camera can confirm the pipe is clean. Ask about this if the drain has blocked before, since a camera check shows what a flow test cannot.
What to ask the engineer
The engineer who takes your job runs a separate business, so the engineer sets the price, the arrival time and any guarantee. Use these questions to compare quotes, since answers differ from one engineer to the next. Write the answers down, because a written note helps if the job changes.
- Is there a call-out charge, and what does it cover?
- Will you check the pipe condition before using a jet?
- Which pressure will you use for my pipe?
- Does the price cover one run or the whole system?
- Can you advise how often the drain needs cleaning?
What it can cost
MyJobQuote lists drain jetting at £70 to £175, while Book A Builder gives £120 to £250 for high-pressure jetting, taking one to two hours. Fantastic Services gives £70 to £125 outside London, and £100 to £150 in London. These are UK guide ranges, not Dundee quotes.
The guides still disagree a little, and none is a Dundee quote. Ask whether the price covers one run or the whole system. Then ask for the price in writing before work starts.
Domestic Drain Jetting questions answered
Is drain jetting safe for my pipes?
A sound pipe usually copes well, although high pressure can harm a cracked or fragile pipe. Ask the engineer to check the pipe first. Ask which pressure they plan to use.
What is the difference between drain jetting and drain cleaning?
Drain cleaning is the aim: removing build-up from the pipe. Jetting is one way to do it, using high-pressure water, while rods and cable machines are other ways. Ask which one suits your drain.
How often should I have my drains jetted?
No fixed rule fits every home. Kitchen drains and drains with trees nearby may still need regular cleaning. Ask the engineer for advice after the first visit.
Will jetting damage my garden or drive?
Jetting works through existing access points, so digging is not normally needed. However, ask the engineer where the equipment will stand and how the water will drain away. Agree this before work starts.
