Maintenance Service Pack

Your premium thermostatic shower system contains a sophisticated thermostatic cartridge and components that over time experience wear and tear, corrosion, and build up of mineral deposits which impair their proper functioning.

To ensure continued safe and enjoyable use of your thermostatic shower system, we recommend servicing it about every 15 years. You should replace the thermostatic cartridge, volume control cartridge, both check valves, and both neoprene washers.

We have assembled these parts into one pack for your convenience.
