When your drains stop flowing, everything else comes to a standstill. Whether it’s the bathroom sink bubbling up in Plympton, or foul smells rising from a kitchen drain in Saltash, you need answers fast — and a fix even faster.

This guide walks you through how to unblock a drain yourself, when to call in the professionals, and why homeowners and businesses across Plymouth rely on Drainblock Services for fast, honest, no-fuss drainage solutions.

Can I Unblock a Drain Myself?

You can try — but it depends on what’s causing the blockage. If you live in areas like Ivybridge or Tavistock, where tree-lined streets and older plumbing systems are common, your blockage might go deeper than surface level.

Here are three methods you can try at home:

How to Clear a Blocked Outside Drain in Plymouth

Homes in Southway, Mannamead, and other leafy parts of Plymouth often face issues with external drains during heavy rain or garden cleanup. Try this:

• ■Remove debris covering the grate: leaves, mud, moss
• ■Use drain rods (only if you’ve done it before — they can get stuck!)
• ■Try an enzyme-based unblocker: better for the environment than harsh chemicals

If the drain’s still blocked, you may be dealing with:

• →Collapsed pipework
• →Tree root intrusion
• →Fat or scale build-up from kitchen waste

That’s when you call in our team. We’ll send a van fully equipped with CCTV drain inspection cameras and high-pressure jetting tools.

What Causes a Drain to Block?

At Drainblock Services, we see a few usual suspects across Devon homes and businesses:

• ■Hair and soap scum in bathroom drains
• ■Cooking grease and food waste in kitchens
• ■Tree roots cracking into underground pipework
• ■Wet wipes, nappies, sanitary items (yes, even the “flushable” ones)
• ■Collapsed clay pipes in older homes

Many of our customers in Yelverton and St Budeaux are surprised to learn their drains are 40–60 years old. If your pipes haven’t been inspected recently, a quick check could save you a future emergency.

How to Prevent Drains from Blocking Again

We don’t just fix drains — we help you keep them flowing. Here’s what we tell every homeowner from Mutley Plain to Millbay:

• ■Avoid pouring oil or grease down the sink — wipe pans with kitchen roll first
• ■Use sink strainers to catch food bits or hair
• ■Flush hot water down drains weekly (great for homes with heavy cooking use)
• ■Never flush wipes — no matter what the packet says
• ■Schedule an annual drain cleaning and inspection, especially in high-tree or high-clay soil areas
