ECM Puristika Watertank O Ring

My ECM Puristika's water tank was seeping a little, and this genuine O-ring fit perfectly and stopped the leak immediately. It's a simple fix that restored the proper seal and consistent water flow.

I was worried the old seal would cause leaks, but this genuine part sits snug in the tank groove and the water flow is steady now.

Installed this O-ring and the water tank seal is now perfect—no more worrying about leaks during backflushing. It’s a snug fit, so take your time pressing it in, but once it's seated it works exactly as it should.
