Is it your drain or Wessex Water's?

It depends on what the pipe serves, not where the problem shows up.

If the drain serves only your property and the blockage is within your boundary, it’s usually yours. If several homes feed into the same run, or your neighbours have problems at the same time, it’s likely a shared lateral drain — and in this area that’s normally Wessex Water’s responsibility rather than yours.

The quick rule: if more than one property is affected at once, it is rarely a private drain.

We’ll tell you which it is before charging you for anything, including if you should be calling Wessex Water instead of us. Road gullies and highway flooding are different again — those are reported to Bristol City Council.

General guidance for the Bristol area. Check with Wessex Water or Bristol City Council for your specific situation — or call us and we’ll tell you what we think you’re dealing with.

Where's the problem?

What's actually going wrong?

Most people call us with a symptom rather than a diagnosis, which is exactly right — working out the cause is our job. But it helps to know what you're looking at. Choose the closest symptom below.

Pick a symptom on the left and we'll explain what it usually means, how urgent it is, and what to do right now — no jargon.

What we do

Clearing a blockage is the everyday job. Finding out why it happened is what stops you calling us again in three months.

Blocked drain clearance

We locate the blockage, clear it properly, then flow test to confirm it's gone rather than moved along the pipe. Blocked manholes and gullies included.

CCTV drain surveys

For homebuyers, landlords, insurers and drains that keep blocking. You keep the footage and a report written in plain English.

Drain jetting & cleaning

High-pressure water cuts through fat, silt and scale to restore the full bore of the pipe, not just a channel through the middle of the blockage.

Drain repairs & relining

Cracked, displaced or root-damaged pipes repaired from the inside wherever possible, so your garden or driveway stays as it is.

Toilets, sinks & showers

Indoor blockages cleared without dismantling half the bathroom, and without leaving the mess behind for you to deal with.

Commercial & maintenance

Scheduled cleaning for pubs, cafés, HMOs and managing agents — so a blockage never decides your closing time for you.

Also: root removal and descaling, blocked sinks, baths and showers, and CCTV rat detection if you’ve got rats coming up from the drains.

How it works

Four steps, in the same order every time. If we can’t complete step four, the job isn’t finished.

The person who quotes is the person who does the work

Flow Sure Drains is run by Anthony Lord. There’s no national call centre, no subcontracted stranger turning up, and no scripted quote from someone who hasn’t seen your drain.

We’ve been on Checkatrade for [X] years, with verified reviews from customers across Bristol and Bath, and around [118] reviews on Google. Public liability insurance is in place and the certificate is available on request.

Most of our work is in central and north Bristol, where Victorian terraces and converted flats share older clay drain runs. That’s the pipework we know best.

What it costs

Most complaints about drainage companies come down to the same thing: nobody said what it would cost until the work was already done. We do it the other way round.

Common questions

The things people most often ask us on the phone.

A standard domestic drain clearance works to a fixed price agreed on site, typically from £[XX]. There’s no call-out fee, and no extra charge for evenings, weekends or bank holidays.

We won’t commit to a firm figure over the phone for a job we haven’t seen — that’s how people end up with a bill that doesn’t match the quote. We’ll tell you honestly what’s likely and what would push it higher, usually a blockage that turns out to be a structural fault rather than a build-up.

It depends on what the pipe serves, not where the problem appears. If the drain serves only your property and the blockage is within your boundary, it’s usually yours. If several homes share the run, or your neighbours are affected at the same time, it’s likely a shared lateral drain and normally Wessex Water’s responsibility.

A simple rule: if more than one property is affected at once, it is rarely a private drain. We’ll tell you which it is before charging you for anything.

Usually, yes. Same-day attendance is most of what we do across Bristol and Bath. When you call you’ll be given a realistic arrival window — [2 to 4 hours] in most cases — rather than an optimistic one, and if we’re running behind you’ll hear from us.

No. We come and look at no charge, and if you decide not to go ahead once you’ve heard the price, there’s nothing to pay and we leave.

Because the previous blockage was moved rather than removed, or because something is still in the pipe catching debris — a fat line, tree roots through a joint, a cracked or collapsed section, or a pipe laid at the wrong gradient.

If it’s happened more than twice in the same place, another clearance only treats the symptom. A CCTV drain survey shows the actual cause, and you keep the footage.

Rarely, on a genuine blockage. They may shift a light build-up near a plughole but won’t clear wipes, roots, silt or a broken pipe. They can also damage older pipework and make the job more hazardous for whoever opens it up.

If you’ve already used one, please tell us when we arrive — it changes how we approach the job safely.

Stop using water in the property — taps, toilets, the dishwasher and the washing machine. Anything you send down the pipe has nowhere to go and adds to what comes back up.

Don’t keep flushing the toilet to test it, and don’t pour chemicals down. If there’s dirty water on the floor or standing outside, keep children and pets away from it until it’s been cleared and the area disinfected.

Yes — pubs, cafés, restaurants, shops, offices, HMOs and managed flats. Kitchen grease lines and shared runs in converted buildings are two of the most common problems we’re called to in Bristol.

For premises that can’t afford to close, planned maintenance works out considerably cheaper than emergency call-outs.

Tell us your postcode and what's happening

That’s usually all we need to tell you what you’re dealing with and when we can get to you.
