On rural properties around Kendall, Kew and the hinterland, the rainwater system is not a backup, it is the water supply. Anthony Martin Plumbing installs and repairs tanks, pressure pumps, switching valves and filtration, and sorts the common failures: pumps that cycle constantly, tanks that run dry too fast, and water that has picked up a taste.

For town blocks, tanks paired with mains changeover valves keep gardens and laundries running on free water with automatic mains backup. New builds often need a tank for BASIX compliance, and it pays to plumb it usefully rather than just tick the box.

Pumps are matched to the household rather than oversold, and existing pumps are repaired where a repair is genuinely worth it.
