When it comes to achieving strong, leak-free joints in plumbing, using the right materials and techniques is critical — and flux is one of the most essential products in any plumber’s toolkit.

At Monsterplumb, we offer a wide range of high-quality fluxes trusted by professional plumbers across the UK. But why exactly is flux so important? Let’s break it down.

What is flux?

Flux is a chemical cleaning agent used during the soldering process. Its main job is to prepare and protect metal surfaces to ensure a clean, reliable joint when joining copper pipes and fittings.

Without flux, even the best soldering technique can fail due to oxidation and impurities on the metal surfaces.

Why is flux essential in plumbing?

✅ Prevents oxidation
When you heat copper pipes for soldering, they oxidise almost instantly. Flux helps prevent this oxidation, ensuring the solder can flow smoothly and bond effectively.

✅ Cleans the joint
Flux helps clean microscopic dirt and contaminants from the metal surfaces,

When upgrading or installing radiators, choosing the right radiator valves is just as important as selecting the radiator itself. The right valves not only control the heat output and efficiency of your system but also influence the overall style of your room.

At Monsterplumb, we stock a wide range of radiator valves, including trusted brands like Drayton and our own stylish Leonova range. Whether you’re looking for practical thermostatic radiator valves (TRVs), manual valves, or designer options in unique finishes, we’ve got you covered.

Why choose Thermostatic Radiator Valves (TRVs)?

Thermostatic Radiator Valves (TRVs) have become increasingly popular in recent years — and for good reason.

✅ Improved energy efficiency
TRVs automatically control the flow of hot water into the radiator based on the temperature you set. This helps maintain a comfortable room temperature and reduces wasted energy, ultimately saving on heating bills.

✅ Room-by-room control
With TRVs, you can set different
