Solvent Weld Waste Pipe

Learn more about solvent weld waste pipes

Solvent welding works by softening the pipe and fitting surfaces with a solvent cement so they bond together as they set. Once cured, the joint is effectively a single piece of plastic rather than a push-fit connection held by a seal, which is why it's chosen where you want a leak-resistant, tamper-resistant run.

It's commonly used on PVC-U waste systems for basins, baths, showers, sinks and appliance connections. Because the joints are rigid, solvent weld runs suit fixed pipework where expansion is managed and access for future dismantling isn't needed. Where movement or easy removal matters, push-fit is often the better call, so plan the method around the run before you buy.

Typical uses

• Waste runs from basins, sinks, baths and showers on domestic and commercial projects.

• Appliance connections such as washing machines and dishwashers where a fixed, secure joint is wanted.

• Straight runs and direction changes made up with solvent weld pipe joints, bends and reducers.

• 40mm solvent weld pipe for bath, shower and sink waste, with other common sizes for basins and larger runs.

• Connections into traps and existing pipework using compatible solvent weld waste fittings.

How to choose the right solvent weld waste pipe

• Match the pipe size to your job or existing layout. 32mm typically serves basins, 40mm suits baths, showers and sinks, so check what the run already uses.

• Confirm the pipe material and that your fittings are made for solvent welding. Mixing methods or incompatible parts is a common cause of problems.

Before you order

• Check the pipe size, fitting type and compatibility with the rest of the waste pipe system.

• Decide whether you need solvent weld fittings only or a fuller set of pipe and components.

• Read the product specifications against the intended use on site so the parts suit the job.

• List everything the run needs first time, so you can get sorted and crack on without a return trip.
