Leaking waste pipe under the sink? Dodgy drainage? I'll replace the damaged section with new plastic pipework - proper seals, correct falls, no more leaks or smells.

When Your Waste Pipe Gives Up

You open the cupboard under the sink and there's a puddle. Or worse - a slow drip that's been quietly rotting the cupboard for months. Or maybe there's no leak yet but you get a whiff of drain smell every time water goes down.

💡 Pro tip: Old waste pipes (especially the original lead or brass ones in Victorian houses) will eventually fail. Better to replace them before they leak through a ceiling or rot your cupboard.


What Goes Wrong With Waste Pipes

Simple really - they're plastic (or old metal), carrying water with bits in it, and eventually they fail:

What to Expect

Step 1: Assess The Situation

I'll look at what needs replacing - just the visible section, or the whole run to the stack? Check what it connects to, what size pipe you need, what fittings.

Step 2: Remove Old Waste

Disconnect at both ends, remove the old pipe. You might get a bit of residual water and a brief smell when the trap comes apart.

Step 3: Fit New Pipe

Cut new plastic waste pipe to size, fit proper connectors, ensure it's falling correctly towards the drain (needs at least 1:40 gradient or it'll pool).

Step 4: Connect & Test

All joints sealed with rubber washers and compression fittings. Run water through - lots of water - and check every joint for drips.

🔧 DIY Tips

Waste pipes are actually one of the more DIY-friendly plumbing jobs if you're careful:

🔧 Tools you'll need

  • Hacksaw or pipe cutter
  • Tape measure
  • Adjustable spanner
  • Spirit level (to check fall)
  • New waste pipe and fittings (usually 40mm for sinks, 32mm for basins)
  • Rubber washers and compression fittings

🔩 How to do it

  1. Turn off water (so sink's empty when you disconnect)
  2. Put a bucket under the trap
  3. Unscrew the old waste pipe at both ends
  4. Measure the new run - you want a fall of about 1cm per 40cm towards the drain
  5. Cut new pipe to size (measure twice, cut once!)
  6. Connect using compression fittings with rubber washers
  7. Hand-tighten, then a quarter turn with a spanner
  8. Run water and check every joint

⚠️ Common DIY mistakes

  • No fall or negative fall (water pools in pipe)
  • Over-tightening compression fittings (cracks the plastic)
  • Forgetting washers (guaranteed leak)
  • Wrong diameter pipe for the job
  • Not supporting long horizontal runs (they sag over time)

💡 Pro trick: Always slope waste pipes downhill towards the drain at about 1:40. Too steep and you get a siphon effect (sucks water out of traps, causes smell). Too shallow and water pools, causes blockages.

Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.

Good to Know

🔧 Old house plumbing? Victorian and Edwardian properties often have original lead or brass waste pipes. They work for decades then suddenly corrode through. Replacing them with modern plastic is straightforward and they'll outlast you.

Shared waste stack? If your waste pipe joins a shared stack (common in flats and terraced houses), I need to make sure the connection's done properly. Building regs are fussy about how you join into shared drainage.

Washing machine or dishwasher waste? These can join into the sink waste if done properly with the right fittings. Saves having separate waste pipes running across the kitchen.

External waste pipes? Exposed to UV and weather, so they perish faster. If your outside waste pipes are old grey plastic (not black), they're probably brittle and due for replacement.

Frequently Asked Questions

How do I know if my waste pipe needs replacing?

Visible leaks under the sink, damp patches in the cupboard below, bad smells (especially when water drains), or slow drainage. Sometimes the pipe's just perished, cracked, or the joints have failed. Old metal or lead waste pipes eventually corrode through.

Can you replace just the damaged section?

Sometimes, but waste pipes are cheap and usually it makes sense to replace the whole run from the sink to where it joins the main drain. That way you get all new seals, proper falls, and no dodgy joints. I'll advise what's best when I see it.

What about waste pipes in the wall?

If it's boxed in or inside the wall, I can sometimes access it from above or below. Worst case, we have to open up the boxing/wall to get at it - but better that than ongoing leaks causing damage. I'll always check for the least invasive route first.

Will it smell while you're working?

Briefly, yes - when I disconnect the old pipe you'll get a whiff of whatever's been sitting in the trap. I work quickly and the smell clears once the new pipe's connected. Definitely open a window.

Do you do external waste pipes too?

Yes - soil pipes, rainwater downpipes, external basin wastes. If it's coming off your property and draining somewhere, I can replace it. External pipes are often exposed to weather and crack over time.
