The Ultimate Guide to Plumbing Fittings for DIY and Trade
Whether you’re a professional installer or tackling a small DIY repair, knowing which plumbing fittings to use makes all the difference.
From copper and compression to push-fit and end-feed, each type has its own strengths — and knowing when to use them can save time, leaks, and frustration.
1. Copper Fittings – The Classic Choice
Copper fittings remain the industry standard for reliability and durability. They’re ideal for both hot and cold water systems and can last decades if installed correctly.
There are two main types:
- End-feed: Requires soldering for a neat, permanent seal.
- Compression: Uses a nut and olive to tighten the joint — no soldering needed.
Copper is perfect for professionals and confident DIYers who want a long-term, heat-resistant solution.
2. Push-Fit Fittings – Fast and Flexible
For quick installations or tight spaces, push-fit fittings are a game-changer.
They connect without tools — simply push the pipe into the fitting until it clicks. They’re great for domestic plumbing where time and accessibility matter.
They can be used with both plastic and copper pipes (check manufacturer guidance) and are reusable in most cases.
3. Compression Fittings – Reliable and Reusable
Compression fittings are incredibly popular for both DIY and trade.
They’re easy to install using basic tools and can be disconnected later for maintenance.
They’re perfect for situations where soldering isn’t possible — like near combustible materials or when working with existing pipework.
4. Solvent Weld – Permanent Plastic Joints
If you’re working on waste pipes, solvent weld fittings are your go-to.
They use a special solvent glue that fuses the plastic together, creating a watertight, permanent joint.
They’re neat, cost-effective, and ideal for bathroom or kitchen waste systems.
