Reasonable Expectations

Unlike many other companies we pride our selves on accurate advise.

Useful Fact: Unless your input water is heated to 24 °C, pumped with a pressure of at least 75 psi and other as a base set of water input parameters you will not attain the manufactures maximum water out put figures.

Most UK water is delivered at a temperature around 12 °C, with a water pressure of around 40 – 45 psi, you will approximately achieve 1 litres per minute (approximately 60 litres hour) equal to 1440 litres per day.

If you increase your pressure, you can expect a higher output. We assemble and install many systems every year and have over many years of using reverse osmosis systems gained a wealth of experience.

If you are going to pump your water, please ensure that your pump has sufficient water flow and sufficient pressure. Beware there are many “water-movers” low wattage, low pressure high volume pumps. You need a pump that will provide around 5 litres per minute at a pressure of over 80 psi constantly to achieve high flow rates of reverse osmosis product water.

At Utopia Koi we have used a 4040 reverse osmosis systems on our ponds for several years with great success achieving well over 1000 UK gallons per day.
