❓ Frequently Asked Questions

What is a straight radiator valve used for?

A straight radiator valve is used when pipework rises vertically from the floor and connects directly into the bottom of a radiator or towel rail without any bends.

Are the reducers visible once installed?

No. The 15mm to 10mm reducers sit internally within the valve and are not visible once fitted.

Can this be used with plastic pipe?

Yes. It is compatible with 10mm plastic barrier pipe when used with a proper internal pipe insert.

When should I use an angled valve instead?

Use an angled valve when pipework comes out of the wall or needs to turn 90 degrees into the radiator.
