Whole House Water Filtration System FAQs | Hybrid Housing Mk2

The center piece of the whole house water filtration system is one or more Stainless Steel water tanks.

Your rainwater is polished by either the Puretec G6 or G7 filtration systems. In addition to killing 99.99% of bacteria with UV rays, the G6  or G7 filters out chemicals as well as sediment and anything else that manages to pass through the pre-tank water quality devices. This not only makes your water taste and smell great, but also prolongs the life of your household appliances.

Your rain water is delivered by a Grundfos Scala2 variable speed pump.  The Scala2 adjusts its performance according to water demand meaning you always get constant pressure at your taps and water appliances.  A revolution in rainwater tank pumps this water cooled pump is quiet and extremely energy efficient.

The variable speed pump and sophisticated filtration system are combined together into a compact unit called Hybrid Housing Mk2. This delivers healthy purified water at a constant pressure.

"I recently ordered a 7500 litre stainless steel round tank from Select Water Tanks and couldn't be happier with it. The process from order to delivery was perfect and I was kept in the loop with manufacture times and a set delivery date. Communication was great through the process and I had to change the delivery date to suit me and there was no issue with this.."

"We have just bought 3 tanks and have now installed them. We found Select Tanks very easy to work with right through to delivery. We had to change the delivery date on a number of occasions and it was never a problem. We are very happy with the quality of the tanks which look great."

Whole of House Filtration Systems FAQs

How long does a whole of house water filter last?

How long the filter(s) lasts depends on lots of factors such as how clean the water is when it enters your tank(s) and how much debris has already entered the tank.

You should plan on washing and cleaning your sediment remover (normally uses diatomatious earth) every 6 months and if you have a ultra-violet filter system and/or a carbon filter system, then every 12 months.

Does a whole of house water filter reduce the water pressure?

Normally the pump will maintain a strong pressure and if you have a variable speed pump then it will adjust the pressure to keep it relatively constant.

The sediment remover filter system will reduce the water pressure slightly as it becomes more clogged with impurities while the carbon filter and/or the ultraviolet filter system will have no impact on water pressure at all

Where should a whole of house water filter be installed?

It is usual to place the filter system and the pump near the tank outlet. If you choose to buy a complete filter system and a pump all in the one cabinet- such as the Hybrid Housing System Mk2 then the cabinet can be placed near the tank or near the house/structure or anywhere along the water line from the tank to the house/structure.

Are whole of house water filters safe?

Yes whole of house water filter systems are very safe because the water is only passing through very fine chalk or sand to filter out any debris.

If you are using an ultra violet filter system then the water is just passing under the ultra-violet light which kills any bacteria in the water and if you are using a carbon filter the water again passes through it safely to remove any taste or odour.
