Where it is used
In basement areas, or where pipes pass through external walls below the water table or in flood-liable locations, a puddle flange helps keep water out along the pipe run. Denso tape or similar should be wrapped around the pipe before the two-piece flange is bolted on, to achieve a watertight seal.

Chemical exposure
Halifax Drain's coatings are tested to withstand chemical exposure between pH2 and pH12, covering the range of household and commercial waste likely to reach a buried drainage run, alongside a 30 day waste water immersion test at 23C and cyclic temperature testing between 15C and 93C.
