Made in the UK from hard-wearing and durable plastic, our 20ltr silver RDWC pots are used for our RDWC Silver Pro series systems. They feature 2 holes on each side to allow for Dual-Flow fittings and 50mm silver pipe. The top of the pot has specially made indents to allow for 6mm airline pipe to enter the pot as well as indents for pot clips to be attached under the surround in order to keep your 16mm airline off of the ground. All other parts are sold separately.
