The QRO4 are often also sold under the names HydrROtwist or PuRO Twist.
The QRO4’s that we stock have the faster 50 gallon per day (200 litre) membrane compared to others which have slower membranes.
These are so easy to change the cartridges on that a 90 year old person would be able to do this so there is no need for expensive service personal, you can easily maintain this system yourself.
This system comes with a 550 kpa pressure limiting valve and your choice of mains connection kits with isolation valve, your choice of 9 different designer faucets (taps).
The QRO4 that we sell we specify that the system contains what is called a self seal valve head. What this means is you don’t need to turn the mains water off, as soon as you undo the first cartridge (Q5605) it has a valve head that turns the in-coming water off. A cartridge change could be completed in under 2 minutes.
System is supplied with John Guest speed fit fittings which are simple push in fittings to make installation a breeze.
The system is complete right down to a roll of thread sealing tape.
