• If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
• On busy streets in Barnstaple, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Things to check before you order

Building over or near a sewer

Building near a public sewer may need permission from the water company. Check before you dig.

Foul or surface water?

Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.

In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.

Working out quantities for your Barnstaple job

An 18 m run of 110 mm drain needs 6 pipes in 3 m lengths (or 3 in 6 m lengths), plus a bend or junction at each change of direction and an inspection chamber where your design shows one. Add pea gravel for bedding and surround and we will price the lot together.

Common questions from Barnstaple

What do I bed drainage pipe in?

Usually pea gravel or a similar granular material around the pipe. We can add it to the order as bulk bags.

What fall should a drain have?

Domestic drains are commonly laid at a gradient around 1:40 to 1:80 depending on the pipe size and flow; follow your approved design or your national drainage guidance (Approved Document H in England and Wales, Technical Handbook section 3 in Scotland, Technical Booklet N in Northern Ireland).
