Blocked Bath or Shower? Here’s What to Do Before You Call

December 09, 20253 min read

A slow-draining bath or a backed-up shower tray isn’t just annoying — it can lead to standing water, bad smells, and even leaks over time.

At EPM, we get called to blocked bath and shower drains across Exeter and the surrounding areas every single week. But the good news is: not every blockage needs a professional to fix it.

Here’s what you can try before picking up the phone — and how to tell when it’s time to get a pro involved.


Step 1: Remove Surface Debris

Most shower and bath blockages are caused by a mix of:

  • Hair

  • Soap scum

  • Shampoo residue

  • Limescale or dirt buildup

Start by lifting the drain cover (if possible) and removing any visible gunk or hair buildup. Use gloves and a drain snake or bent wire hanger to fish out what you can.


Step 2: Try a Plunger

You don’t need a massive toilet plunger — a small sink plunger can help dislodge minor blockages.

  • Add a little water to cover the drain

  • Seal the plunger over the hole and pump firmly a few times

  • If the water suddenly drains — you’ve cracked it

Be cautious not to plunge too aggressively, especially with older seals.


Step 3: Use Boiling Water (Carefully)

Pouring freshly boiled water (not straight from the kettle) down the drain in stages can help melt soap and grease.

Don’t do this if your plumbing includes plastic waste pipes that may warp or if you suspect there’s a deeper issue — this is best for minor slow drainage.


Step 4: Bicarbonate and Vinegar (Eco Option)

For a natural option:

  • Pour half a cup of bicarb down the drain

  • Follow with half a cup of white vinegar

  • Cover the drain, wait 10–15 minutes

  • Flush with hot water

This can shift minor blockages — but won’t touch more stubborn issues.


When to Call a Professional

If any of the following apply, it’s time to book someone in:

  • Water won’t drain at all

  • You’ve tried DIY fixes with no improvement

  • There’s a foul smell that won’t go away

  • Water is backing up into other fixtures

  • You’re in a flat or shared system where one blockage affects multiple areas

At EPM, we use drain rods and mini jetting equipment to clear blockages quickly — and without damaging your bathroom.


Final Word from EPM

If your bath or shower has been draining slowly for weeks, don’t let it turn into a full backup.

Try the simple fixes first — and if they don’t work, we’ll get you sorted quickly, cleanly, and without any mess left behind.
