What needed doing

The backflow preventer needed servicing.

What we did

We dismantled the backflow preventer and the strainer upstream, checked and cleaned the internal parts (valves, springs, strainer basket) and put everything back together.

The result

The backflow preventer is clean and reassembled, with its gauges in place for checks.
