I have a single-lever valve for my washing machine. It is manufactured by Symmons (W400 or W500 - http://www.symmons.com/products/res_product_detail.cfm?id=401&category=9&function=24). It is only 2 years old and it was installed by a professional plumber. However, the valve does not shut off when I move the lever to the off position. Is there something a DIYer can do, or should I call the experts?
Thanks in advance!
