Rainwater Tanks Mandurah

Rainwater tank installs, connections and pump repairs for homes across Mandurah and the Peel, from suburban blocks to rural properties.

Rainwater tank plumbing in Mandurah

A rainwater tank only earns its keep if it's plumbed in properly. Drainpro Plumbers installs new tanks, connects existing ones to the house and garden, and repairs the pumps and pipework that keep them running. Whether you're on a suburban block in Halls Head or a rural property in Karnup, we'll set it up so it works and meets WA plumbing rules.

Tank jobs we do

  • New tank installs: setting the tank, connecting downpipes and gutters, and running the overflow to a safe spot.
  • Connecting to the house: plumbing tank water to toilets, the laundry and garden taps.
  • Pumps: supplying and fitting pumps, and repairing ones that won't hold pressure or keep cycling.
  • Mains switching: setting the system up to change over to scheme water when the tank runs low.
  • Backflow protection: keeping tank water and scheme water apart where the two supplies meet.
  • First-flush diverters and screens: keeping leaves, dust and debris out of the tank.
  • Overflow and stormwater: connecting the tank overflow into your stormwater so it doesn't flood the yard. More on stormwater
  • Repairs: leaking tank outlets, broken fittings and damaged pipe runs between the tank and the house.

Getting the most out of your tank

Clean gutters make cleaner tank water, so it's worth checking them before winter rain. Screens and first-flush diverters stop most of the muck before it reaches the tank, and a pump in good condition saves power and wear. If your gutters or downpipes need work as part of the job, we can sort that in the same visit. More on roof plumbing and guttering

Got questions?

Rainwater Tanks: common questions

Answers to the questions our customers ask most. Can't find yours? Give us a call.

Can rainwater be connected to my toilet and washing machine?

Yes. Toilets and the cold tap on the washing machine are the most common indoor connections, along with garden taps and reticulation. We run the pipework, fit a pump, and set it up so the house switches over to scheme water if the tank runs low.

Do I need a backflow device with a rainwater tank?

If your tank is connected to plumbing that also has scheme water, the two supplies have to be kept apart so tank water can't flow back into the mains. We fit the right protection for your setup and make sure the job is done to WA plumbing rules. More on backflow prevention

Can you fix my rainwater tank pump?

Yes. A pump that cycles on and off, won't build pressure or won't switch off usually points to a leak, a failed pressure switch or controller, or air in the line. We find the cause and either repair or replace the pump.

What size rainwater tank do I need?

It depends on your roof area, what you want the water for and how much room you have. A tank just for the garden can be quite small, while one supplying toilets and the laundry needs more capacity. We'll talk it through with you on site before you buy.

Do you work on rural properties outside Mandurah?

Yes. Many of our tank jobs are on bigger blocks around Karnup, Nambeelup, Lake Clifton and the Yunderups, where a tank is part of the main supply. We service all of Mandurah and the Peel region. See the areas we cover

Do you charge a call-out fee?

Only after hours. A call-out fee applies on weekdays after 5pm and before 5am, on Saturdays after 1pm, and all day Sunday. Any other time there's no call-out fee, and you only pay once you've accepted the job.
