Tip of the Day

Are you sure you need Category 5, Type AB Spill Slot / Air Gap protection on your Inlet? If you do, proceed to the ATCM Type AB Air Gap and Spill Slot Calculator for design details.


In the vast majority of commercial installations a simple Type AF Air Gap, providing Category 4 risk protection, is more than sufficient for 99% of all tank and cistern installations. 

This is a much simpler and lower cost solution, details of which can be obtained from WRAS publication, IGN No. 9-04-04 , Section 11.

Currently many of the specified Type AB Spill Slots are being removed or blocked off on new tank assemblies on direction of the Local Water Inspector at considerable additional cost and disturbance to the contact.

Current Water Regulations require all new or substantially modified water supply installations to be submitted to and approved by the local Water Undertaking before installation commences. Make sure you benefit from this service.  ___________________________________________________________________________________________________________________
