The Maintenance Tray solves the challenge of cleaning fixed and difficult-to-reach tank inlet screens. It sits on top of these screens to become a second, removable screen with an easy-to-reach protruding handle. Simply lift it off, toss any leaves away, rinse and put it back. Too easy.
The Maintenance Tray’s mosquito-proof 955 micron stainless steel mesh provides an added layer of protection against these tiny pests. For “dry” Rain Harvesting systems without rain heads, it also plays an important role in preventing leaves from contaminating your rainwater.
Maintenance Trays provide additional leaf filtering over the area where water directly enters your tank assisting with filtering leaves & debris.
Maintenance trays with 955 micron mesh are legally required in some countries and regions (including many Australian states) to prevent mosquitoes from breeding in your tank, ensuring a secure system. Maintenance Trays are installed in tank inlets to keep mosquitoes and other pests out but to allow water to pass through at full flow.
You should regularly clean your Maintenance Tray to ensure the water flowing into your rainwater tank isn’t obstructed or contaminated by leaves and debris.
To clean, grab the handle, remove your Maintenance Tray from your tank screen and brush away larger leaves and debris. If necessary, you can hose it off remove any finer debris. Replace on top of your tank inlet screen.
To improve your rainwater quality, we recommend inspecting your Maintenance Tray every 3 months or between rainfall events.
Alternatively, you may wish to consider installing a Maelstrom Filter rather than using a Tank Screen and Maintenance Tray.
Water bounce occurs when fast flowing water from your tank inlet pipes “bounces” off your mosquito-proof tank inlet screen, reducing your water catchment efficiency. This may occur during heavy downpours, when too many pipes are feeding a single screen, or if your mosquito-proof tank inlet screen has become obstructed by leaves and debris. Replacing your tank inlet screen with a mosquito-proof Maelstrom filter is an effective way to prevent water bounce and improve your water catchment efficiency.
It is common to have two 90mm (3″) pipes feeding a single tank screen. If additional pipes are plumbed, it is important to consider the capacity of your tank overflow outlets. Your outlets should balance your inlet pipe volume so that the combined cross-sectional area of the inlet pipes does not exceed the cross-sectional area of the outlet. You may need to install an additional tank overflow outlet or enlarge your existing one to accommodate the volume of water from additional inlet pipes.
Your tank outlet may be blocked by a blocked Mozzie Stoppa or another obstruction. Alternately, the bottom of your tank overflow may sit above the base of your tank inlet screen and/or tank inlet.
Check your overflow outlet for the presence of a Mozzie Stoppa or other obstruction. If a Mozzie Stoppa is installed, remove and inspect it and clean if necessary before reinstalling it at the outlet or replacing with a Mozzie Stoppa Easy-Clean. Remove any other obstructions from your tank overflow outlet.
If a blocked Mozzie Stoppa or other obstruction is not the cause of your inlet overflow problem or if your inlet overflow problem persists, check to ensure that you have an appropriate height tank overflow for your tank. The bottom of your overflow should sit below the level of your tank inlet screen. If you have an overflow that sits above the base of your tank inlet, you will need to replace it with a lower tank overflow.
Fine particles can accumulate on your tank screen’s mosquito-proof mesh. This may block the water flow. To prevent this problem, regularly maintain your tank screen or replace it with a Maelstrom filter.
