Noramly prefilters should be changed every 6 months.

The only way to up Ro production is to either add a pump to increase the pressure, which probably isn't necessary, or add a second RO member, into which the 'waste' water from the first membrane goes. That's what Ive done, and it must be close to double the output.

You can also add additional membranes in parallel and fit an extra flow restrictor. Some koi keepers who run RO units have 3 membranes each in parallel with a flow restrictor after each membrane and then another one after the three outputs have been recombined. This gives a really low rejection rate and high outputs - ideal for a koi pond where you need a lot of water.
