WRAS Approved Standpipes
WRAS Approved Standpipes are available from Delta in three principal formats, Single Headed, Double Headed and Contractors.
All models are fitted with WRAS Approved Double Check Valves and manufactured in materials accepted within the Water Industry in grades LM6 & LM4. The Single & Double Headed WRAS Approved Standpipes use tube material to BS1474 6082T6 and incorporate base washers manufactured from a WRAS Approved EPDM liner or nitrile material.
The use of Approved products such as Standpipes and Hoses is often a requirement of the local authority where drinking water transfer is concerned. Delta’s AQUASTAR Drinking Water Hose is often used in conjunction with these Standpipes to ensure all criteria are met appropriately.
To compliment the range Delta also offer a range of Contractors Standpipes. These are supplied in ¾” versions with hose union bib tap (BS1010) and WRAS Approved double check valves to BS6282 to fit onto a BS750 Type 2 Hydrant Valves via a 2½” London Round Thread base. Supplied 1 metre in lengths and manufactured from heavy gauge epoxy coated galvanised tube, the Contractors Standpipes are also available with a twin Bib Tap Option or fitted non-return outlet valve.
