About this course

Most domestic plumbing needs no registration, which surprises people, and it is still governed by national law that carries criminal penalties. This course teaches the law first, then the skills.

It covers fluid categories and backflow, which is what the whole regulatory framework exists to prevent, then the three joint types and what makes each one fail, then diagnosing leaks by when and where they appear.

It is unambiguous about gas: only a Gas Safe registered engineer may touch it, and no amount of confidence or competence changes that.

What you will be able to do

  • Apply the Water Supply (Water Fittings) Regulations to real work
  • Classify a risk by fluid category and select the right backflow protection
  • Make soldered, compression and push fit joints and explain each failure mode
  • Diagnose a leak from its timing and location
  • State exactly where the law stops you and registration begins

Questions

Can I legally do my own plumbing?

Most domestic water plumbing, yes. You must still comply with the Water Supply (Water Fittings) Regulations 1999, notify certain work in advance, and never touch gas, which requires Gas Safe registration by law.

Does my outside tap really need a valve?

Yes. An outside tap requires at least a double check valve, and a hose left in a butt, pond or bucket creates a category 5 backflow path into the drinking main. It is the commonest domestic breach in the country and it costs about eight pounds to fix.
