Blocked Drain Emergency: What to Do First

Stop putting water into the system

This is the single most useful thing you can do and it costs nothing. Every litre that goes into a blocked drain has to come back out somewhere inside the building. Tell everyone in the house to stop using taps, toilets, showers, the washing machine and the dishwasher. If an appliance is mid cycle, stop it at the machine rather than waiting for it to finish, because a washing machine discharging twenty five litres into a full stack is what turns a nuisance into a flood.

If you are in a flat or a terrace on a shared run, knock on the neighbours as well. A shared soil stack means their bath emptying will arrive at your gully whether your taps are off or not, and on a converted tenement stair that is the usual reason a blockage keeps overflowing after the householder has done everything right.

Protect the property while the water is still moving

Lift anything absorbent off the floor in the affected area. Rugs, cardboard boxes, pet bedding and the bottom shelf of a utility cupboard all soak up contaminated water and all become a disposal problem afterwards. Move them before the water reaches them rather than after.

If waste is coming up through a ground floor shower or bath, do not try to plug it. A blocked plug in a surcharging system simply moves the discharge to the next lowest opening, which is often a toilet pan or an under sink connection where the mess is worse. Let it come up where it is easiest to clean and contain it with towels and a bucket instead.

Find out how far the problem goes

Lift the manhole cover nearest the property and look. If the chamber is full or running high, the blockage is downstream of it and the whole property is affected. If that chamber is empty and clean, the problem is between the house and that point, which usually means a single branch such as the kitchen waste or the soil pipe from one bathroom.

Where there is more than one chamber, work outwards from the house until you find one that is running clear. The blockage lies between the last full chamber and the first empty one, and telling us that on the phone genuinely shortens the visit because we arrive knowing whether we need jetting gear, a rod set or a camera.

• Full chamber nearest the house: blockage is in the outgoing run.
• All chambers full to the boundary: possible public sewer issue, worth reporting to Scottish Water.
• Only one appliance affected: it is a branch, not the main run.
• Every appliance slow but nothing overflowing: partial restriction, still urgent but not a same hour job.

What is safe to try yourself

A plunger on a single slow appliance is fine and often works. So is clearing an external gully by hand with gloves on, because leaves, silt and a decade of grit sitting in the trap is a very common cause of a yard flooding in heavy rain. Neither of these can make the situation worse.

Caustic drain cleaners are a different matter. On a fully blocked run the chemical sits in standing water, does not reach the blockage and remains in the pipe as a hazard for whoever opens it up. If you have already poured some in, tell the engineer when they arrive so they can work safely.

When it stops being a DIY job

Call someone out if sewage is entering the building, if a toilet cannot be used at all, if the chamber at the boundary is full, or if the same drain has now blocked more than once in a few months. The last one matters because a repeat blockage is a symptom rather than an event, and clearing it again without looking inside the pipe just buys a few weeks.

We run a genuine twenty four hour call out across West Lothian, Edinburgh, Falkirk, Lanarkshire and Fife with no call out charge, and we carry jetting equipment and a camera on the same van so a clearance and an inspection happen in one visit rather than two.

After the drain is running again

Once flow is restored, run each appliance in turn and watch the chamber. A run that clears and then slows again within minutes has a restriction still in place further down. It is far cheaper to have that found on the same visit than to book a second call out a fortnight later.

Clean affected floors with a disinfectant suitable for contaminated water, ventilate the room, and photograph any damage before you tidy up. If you intend to claim on buildings insurance, the photographs taken before the clean up are usually the ones the insurer asks for.

What it costs and what to expect from us

There is no call out charge, including at night and at weekends, and we quote before we start rather than after. A straightforward domestic clearance is a fixed price job, and where the drain turns out to need a camera or a repair we price that separately so you can decide rather than being committed on the spot.

We cover West Lothian, Edinburgh, Falkirk, Lanarkshire and Fife with our own engineers and our own equipment. That matters at two in the morning, because the jetter, the rod set and the camera all arrive on the same van and the engineer who clears the blockage is the one who can tell you why it happened.
