Frequently Asked Questions

Can I install the Grey Water System myself?

Yes. Both the Maxi Pro and Maxi have been designed for the DIY homeowner market. The DIY handyman will be able to install our grey water systems, in the average home, on a Saturday morning for a difficult installation or within 2 hours for a standard “above ground” installation. The minor plumbing work required is only to connect the unit to the existing down pipes. You don’t need to dig up your garden to accomodate ugly storage tanks, lay meters of additional plumbing pipe or hide the unit. We are proud of our units good looks and we are sure you will be too.

What is Grey Water?

Grey water is used water from the bath, shower, bathroom sinks. This fairly clean water is ideal for irrigation systems in the garden. Grey water excludes water from the kitchen and toilets – this is called black water or sullage.

Do I need to use chemicals to treat my Grey Water?

No. As the grey water is used directly from the bathroom and is never stored for long periods, thus this water is relatively pollutant and bacteria free. The grey water is never given a chance to stagnate, reducing the chance of offensive odours and / or bacteria proliferation.

Why should you NOT use a grey water storage tank?

Garden ResQ never stores grey water as it is illegal in most countries. We follow various international health standards that state that grey water must never be kept for longer than a day. Our recommendation is “Use It Or Loose It “. Stored grey water results in a pathogen bloom that may be a health risk – never mind the terrible odour when left to stagnate. The Garden ResQ Maxi make use a surge tank to allow for larges amounts of water entering the unit initially when the bath plug is pulled or there are more than one inlet serving two bathrooms – but begins diverting water to your garden almost immediately.

What type of irrigation may be used?

Both the Maxi and Maxi Pro units have been designed for use with the “pyramid” type sprinkler heads. This type of sprinkler allows for a single large outlet that delivers large water droplets. The large hole in the sprinkler head copes very well with fine debris that is often characteristic of grey water. Grey water irrigation should not incorporate drip irrigation, pop up or mist sprayers – as these consist of very small water exit holes and will block with the use of Grey Water – no matter what you have been told.

How much does it cost to run the system?

On average, with a family of 4, showering or bathing once a day, the system will cost you approx. R0.06 a day – thats R1.80 per month added to your electricity bill. Your water savings could be as high as 600 litres of water a day. That’s plenty of water for garden irrigation DAILY.

Must I clean the interior of my grey water recycling unit?

It is normally necessary to clean the interior of any of the Garden ResQ grey water recycling systems every few weeks. This will take no more than 5 minutes. You can, should you notice a slight grey water odour when you irrigate, flush the surge tank with a jet of water from your garden hose once the unit has been disconnected from the main power supply.

This direct jet of water will loosen any grime that has built up over the months and, without any rubbing or scrubbing, will leave your unit as good looking as the day you bought it. A litre of white vinegar may be added to the unit for 30 minutes before activating the pump again.

It is good practice to flush the system with fresh water in this way every few weeks. This will also assist in getting rid of any sludge which may have settled on the bottom of the unit over time. The small amount of vinegar in this concentration will not harm your garden

How often should I clean the Grey Water System filter?

This depends largely on use i.e. the number of occupants in the household and the number of showers / baths that each occupant has during the day. As with any filter, regular maintenance will ensure many years of service. Check your filter weekly to determine your unique requirements.

What steps should be taken when cleaning the filter?

As this filter will contain hair, soap scum and other debris, it is recommended that due caution is taken at all times when working with any grey water. Please wash your hands after cleaning the filter.

May I use harsh chemicals when cleaning my bath or shower?

Remember that any harsh chemical product used in the bath or shower will end up in the garden. Please use these products sparingly. Use of bath oils, bubble bath and bath salts can be used however they should be used sparingly. The ENCHANTRIX range of chemical free cleaners is recommended as it does not harm flora or fauna. Any other biodegradable products are recommended. General household cleaners are safe in the quantities recommended on their labels.
