Trade Waste Arrestor Installation Support

The installation of a Trade Waste Arrestor must be in accordance with current plumbing regulations.

When installing, consider the following:

• Outside installations must be a minimum of 50mm above ground level to exclude stormwater.
• Chequerplate covers can be fitted with recessed drop handles and/or frame to suit brick paved areas.
• Cast iron covers, with built-in inspection opening, can be supplied in place of standard chequerplate covers.
• Epoxy coating is available upon request.
• Increments are available on request.
• Heavy duty concrete covers with cast in cast iron covers and frames are available.

Please note: Where circular gas-tight inspection covers are fitted a minimum of 600mm vertical clearance between the underside of the cover slab and the static water level in the arrester is necessary to facilitate routine servicing.
