RAINWATER FILTER SYSTEM

3 Stage Rainwater Harvesting

If you’re searching for a solution for rainwater harvesting or your private water supply, look no further than our rainwater filter system. Supplied pre-assembled as a kit ready for installation with easy to adapt 3/4″ BSP female brass reinforced ports, high quality moulded head and 3 carefully selected filter cartridges. This robust and reliable filter system is suitable for use on its own, or as part of a larger filtration cascade in conjunction with a UV system (suitable for flow rates up to 2,500 litres per hour).

Stage 1: 90 Micron Stainless Steel Mesh Filter
The first stage is designed to catch large debris and particulate such as leaves or dirt, that would otherwise block the filters downstream. Featuring a spring assembly and drain valve for easy flushing of particulate, without needing to remove the filter.

Stage 2: 25 Micron Wound Sediment Filter
The second stage offers finer filtration down to just 25 micron, removing silt, dirt and fine sediment. This helps to improve the lifespan of the carbon block filter and if used in conjunction with a UV system, prevents shadowing behind the UV light.

Stage 3: Carbon Block Filter
The third and final stage utilises a carbon block filter to remove organics, solvents, herbicides and other contaminants, whilst tackling unpleasant colours and odours that may be in the water.

How Often Do I Need To Change The Filters In The Rainwater Filter System?
The mesh filter should be cleaned when visibly dirty, using the built-in spring-operated valve to flush the filter without removal. If extremely fouled, the mesh filter should be removed from the housing and cleaned thoroughly. The wound sediment filter and carbon filter should be changed every 6-12 months depending on use.

Why Choose Our Rainwater Filter System?

  • High strength triple filter housing suitable for outdoor use
  • Clear filter bowls for visual checks of filter condition
  • Brass reinforced 3/4″ BSP female inlet and outlet
  • Supplied pre-assembled ready for installation
  • Recommended for use with a UV system

Very pleased with the service. There was an issue with the water softener I ordered initially, but then following communications made the replacement process quite pleasant. Happily recommend this company. Thanks to Becky for working with me. Great follow up support 😊😊😊

First time using this company and product and i wasnt dissappointed. Communication was easy and quick resulted in an easy order and now having fitted the filter i can say its a great product easy to install and appears good quality apart from the four mild steel bracket screws stainless would have been better considering the environment these are fitted. All in all, very pleased and would highly recommend .

Excellent local company and genuinely lovely people to deal with. Really helpful and knowledgeable, with great advice about my water softener and the correct salt to use. They even gave me some resin cleaner at no charge, which was a very kind gesture. Fantastic friendly service and I’ll definitely be returning for my salt in future. Highly recommended.

Excellent service. Product proved my softener was not working as it should. I fully serviced it and cleaned with Resin Clean returned to service and it is now working as designed. Very pleased.

If you're thinking about a water softener then i HIGHLY recommend Ultra Soft Water Softeners Ltd. Great softeners and exceptional customer service. The water softener I bought needed some adjustments with the installation setup where I supported throughout. The customer service is honestly next level. I had countless calls with Becky Gillett, the Sales Manager, over a period of months to get to the bottom of it. She was incredibly patient with me, staying on the phone and doing video calls to walk me through the programming instructions step-by-step while I changed the settings and ensured all was installed correctly. All the staff here have been great, but Becky really stuck with me from start to finish to make sure it was sorted and working well. It runs like a dream now. HIGHLY recommend them!

Easy to order, quick delivery, good communication. Resclean worked a treat; one treatment cycle and soft water is back again from our 12 yr old softener!
