Bristan thermostatic valves are designed to be versatile, but please check the specific technical data sheet for your model's pressure range suitability.

Yes, thermostatic valves generally have an adjustable maximum temperature stop for added safety.
The Onza is designed for standard exposed valve plumbing, but professional installation is recommended to ensure correct alignment.
Check the water pressure of your home system to ensure it meets the minimum requirements for a thermostatic valve.
Inspect the shower head and hose for any debris or lime scale buildup and clean as necessary.
Ensure no mineral deposits are jamming the mechanism; if the issue persists, contact a professional to inspect the valve cartridge.
Installation of the Onza exposed shower valve should be performed by a qualified plumber to ensure all pipe connections are sealed correctly and the riser rail is plumb. Ensure your plumbing system is compatible with thermostatic pressure requirements before purchase. For routine maintenance, wipe down the valve and riser kit with a soft, damp cloth after use to prevent lime scale accumulation. Avoid using abrasive sponges or harsh acidic cleaners on the black finish, as these can scratch the surface or strip the coating over time. Periodically check the riser rail mounting points to ensure they remain secure against the bathroom wall.
