anyone have a recommendation for a plumber in lausanne?

Our washing machine was installed by Confort Service (http://www.confort-service.ch/)

They managed to send a guy who spoke some English, so we could understand each other. I can't say it was cheap (the total cost of the installation was more than the original price of the washing machine!), but the reason might have been that they had to purchase some additional appliances in order to connect the washing machine.
They provided a quotation in advance, so it was not a surprise.

In overall, they did a fair job.

We had a good experience with:

Just wondering if anyone has any updated recommendations for plumbers in Lausanne - especially one who can speak/understand some english!
