Tips for Installing a Rainwater Tank

February 16, 2023

Installing a rainwater tank to collect rainwater runoff from your roof is an excellent way to store rainwater for later use. If you’re interested in installing a rainwater tank, you’ll need to contact the Gold Coast plumbers at In Deep to ensure it is installed properly, and if you want it connected to a main water supply, a plumber is required. However, there are certain things you can do yourself to reduce the cost of having everything done by the plumber. Here are some tips to get you started.

Install Before the Wet Season

A rainwater tank is only good when it rains, so install it or have it installed before the wet season begins. This way, you’ll be able to collect as much rainwater as possible to sustain you during the dry season. Just remember that plumbers who install rainwater tanks get very busy before and during the wet season so to ensure you get your tank installed when you want it, schedule your installation appointment well ahead of time.

Prepare the Ground

One way to reduce the expenses related to rainwater tank installation is to prepare the ground properly. The ground where your tank is going to sit must be completely level and larger tanks may require a concrete or sand foundation. This is definitely something you can take care of before the plumber arrives to install your tank, especially if you are installing a small tank. 

Check your tank’s user guide to help you determine where your tank should be located and it’s always a good idea to get a plumber’s opinion as well. If possible, have the plumber who is going to install your rainwater tank come to your house well before the installation to help you choose the best location for your tank. This way, you can prepare the ground properly before the actual installation date.

Prepare Your Gutters

The rainwater that your rank is going to collect will flow from your roof, through your gutters, and into your tank. As such, it’s vital that you make sure your gutters are in great shape before you install your tank. Otherwise, it will be a waste of time. Your gutters should be free from debris and leaves so that the water flows freely to your tank.

If you have any damaged gutters, now is the time to get them repaired so they don’t leak. Leaks are rainwater you won’t collect in your tank, so to collect the most runoff water possible, your gutters need to be leak free. Plumbers usually won’t fix your gutters, so you may need to do these repairs yourself or look into hiring another professional that does handle that task. 


The tank isn’t the only component of your rainwater collection system that you’ll need to make it functional. Ensure you have the pump, first flush diverters, backflow prevention valves, connections, pipes, and fittings that go with your tank before you attempt to install it. Additional accessories you may want to consider include mosquito-proof mesh, gutter protection guards, and a tank stand. Check with your plumber to see what they recommend in your area.


There are many reasons to install a rainwater tank, including water conservation, superior tap water quality, self-sufficiency, and economic savings. Whatever your reason is for installing one, make sure the installation goes well by planning ahead using these tips.
