I searched high and low for a rectangular overflow kit, and had trouble determining dimensions of components when contacting other suppliers ad even on the McAlpine product website. I called Stevenson Plumbing ahead of ordering to confirm some of the dimensions and the customer service was outstanding. The order and payment process online was quick and easy and I had my item within two days. Highly recommended.
After almost 2 yrs searching for a rectangular overflow for a Paul of Derby 1960's sink,a "last hope" click on a link to this website answered my prayers. Item ordered & delivered within 48hrs,a perfect fit - no leak. Also a lot cheaper than a new sink unit. Excellent service from Stevenson Plumbing & Electrical Supplies and will be recommending their website to others. Many thanks for your rapid service.
