does anyone know where i could aquire a 50 mm copper manifold. The actual manifold supplies 10 apartments situated in a multi storey building. It tee's off the main service pipe to a stop cock and then tee's off to 22mm to each apartment. the problem i have is the stem tee'ing off from the manifold is leeking from the soldered joint and i am looking at the worst scenario should resoldering not stop the leak
