Some other poster saved my butt my putting up pictures of a Foremost shower valve cartridge.

The company "Foremost Groups" is being cagey on admitting whether they supplied this shower valve.

Anyone here have any contact with this company?

Contact them at; Foremost Canada (http://www.foremostcanada.com/products.php)
Good luck, Tom
