The waste pipe and trap under your sink do an unglamorous but constant job: every time water drains, they carry it away under pressure of flow, through joints that see movement, heat changes and residue. When one of those joints fails, the leak behaves differently from other sink leaks — it tends to drip during and after each drain, so the cupboard below never fully dries. That is why this fault deserves a proper repair rather than a tightening and a hope.
What Makes Waste Pipes Leak
The trap — the U-bend that holds back drain smells — is joined to the basin waste above and the branch pipe below with compression unions and rubber seals. Those seals flatten with age, plastic unions crack when overtightened, and vibration from the washing machine or dishwasher sharing the run gradually loosens fittings. Flexible waste sections split along their corrugations. Occasionally a previous repair was made with the wrong seal or the wrong-sized washer, and it simply never held.
Why It Should Not Be Left
Because the leak coincides with draining, it is easy to miss — you only see the water after the sound has gone. Meanwhile the cupboard floor absorbs a small quantity every single day. Chipboard swells, mould colonises the dark corners, and water can find its way to the ceiling below. There is also a hygiene point: waste pipe water is dirtier than supply water, so a slow drip is more than a nuisance. The repair itself is usually modest — the damage from waiting is rarely.
How We Diagnose It
We dry the pipework and run a full bowl so the leak shows itself on demand, marking exactly where water appears. We then inspect each union, the trap body, the basin waste connection above and the branch pipe below. It is important to check the whole run, because water travels along the outside of the pipe and can appear metres from the actual failure. Once we have the true source, we explain what has failed and why, before any parts are replaced.
How We Fix It
The standard repair is to renew the failed component: a new trap with sound rubber seals, new compression washers at the unions, or a replacement section of waste pipe where the plastic has cracked or split. We cut and fit to length, align the run so water flows without back-fall, and tighten everything evenly — correctly torqued, not muscled. Before leaving, we run a full bowl and a continuous flow, watching every joint for any sign of moisture.
Preventing Future Waste Leaks
Do not hang cleaning products or heavy items on waste pipework, and leave access to the trap reasonably clear so problems are visible early. If the basin or its fittings are themselves past their best, our sink replacement service can be arranged in the same visit. If you have flexible corrugated waste sections, ask us about replacing them with smooth pipe during the next visit — they are a common leak point. An annual glance under every sink is worth more than any product.
When To Call Us
Call us when you see drips after the sink drains, when the cupboard floor stays damp, when there is a smell of waste water under the sink, or when a joint keeps working loose no matter how often you tighten it. Those signs all point to seals or fittings that need renewing, not adjusting.

Questions people ask about sink waste leak repair
Straight answers to the things customers ask most often before booking.
Why does the leak only appear when the sink drains?
The waste pipe only carries water while the basin is emptying, so a failed joint there drips during and after each drain. Supply-side leaks behave differently and drip constantly. The pattern itself points to the waste run or trap.
Can I seal the joint with tape or silicone?
It will hold briefly and fail, because waste joints move as water flows and drains.
Do you replace the whole trap or just the washer?
Whichever is right. If the trap body is sound and only a washer has perished, we renew the washer. Cracked or old traps are replaced outright, since a new trap costs little and avoids a second call-out.
Is a waste pipe leak a hygiene problem?
Yes. Water from the waste side carries food residue and bacteria, unlike a clean supply leak. It drips into the cupboard where you store cleaning products and food, which is another reason to repair it promptly.
What if the leak is inside the wall or floor?
We will tell you if the leak sits beyond the visible waste run. In most cases the trap and its connections are the source, and we find and fix it within the 60-minute visit. Anything unusual we explain before starting.
