Nothing new about Villeroy & Boch in business from 1748. It's clearly a Foo-Foo designer company. The website is clearly nothing but sales related info with nothing about repair. The question I always have with Foo-Foo is parts availability! When your Foo-Foo crapper craps out what do I have to do to get the parts it needs? If it's the only toilet in the house and you're waiting for a part to ride across the big pond on a slow boat this could be a big problem. Hopefully, it uses stock off the shelf parts but the website gives no information as to what is inside the tank and where local distributors are.
I would check with your local distributor and see what is inside that tank and if the parts are available. Common off the shelf parts is good, propietary parts available only through Villeroy & Boch is bad.
