The twofold or double headed standpipes are connected to a typical base segment, yet can be introduced as a solitary head by embedding a clear fitting into one of the power source.

In situations where the standpipe will tap a drinking central pipes, then the training is to embed a one-way or no-return really take a look at valve to keep tainting of the primary water from perilous water that can stream back from the hose into water framework.
