Frequently asked questions

All of Pakistan. Our technicians travel to every province and region, including Gilgit-Baltistan and Azad Kashmir, so you don’t need to live in a big city. Our Service Areas page names some of the places we work. If your town isn’t there, send us a message or request a callback and we’ll arrange a visit.

Yes. We install and look after domestic RO systems for homes, and larger filtration plants for offices, shops, restaurants, schools, clinics, factories and other commercial or industrial sites.

Send a quote request, book a visit, or message us on WhatsApp. Tell us your city, your water source (tap, bore, tanker) and roughly how much water you need each day. We’ll get back to you to discuss the options and the next step.

We look at your water source and quality, how many people or how many litres a day the system needs to supply, the space available, and your water pressure. Then we recommend a system and explain why it suits you.

A standard under-sink home RO system is usually a short visit. Commercial and industrial plants take longer and are planned with you in advance. We confirm the time when we book the installation.

• A water inlet near where the system will go
• A drain point for the waste water from the RO process
• An electrical socket if the system has a pump or UV lamp
• Enough space under the sink or on a wall for the unit

If something is missing, we’ll tell you during the visit what is needed.

Yes. RO membranes need a certain pressure to work well, so where supply pressure is low a booster pump is normally added. We check the pressure during the visit.

The membrane needs a flow of water to carry away the salts it holds back, so some water goes to the drain. Many people reuse it for cleaning or plants. The ratio depends on the system and your water.

It depends on your water quality and how much you use. As a general guide, sediment and carbon pre-filters are often changed every few months, and RO membranes last longer. We’ll recommend a schedule based on your water and usage.

• The water tastes or smells different
• The flow from the tap has become slow
• The TDS reading of the filtered water has gone up
• The tank takes longer to fill, or the pump runs constantly
• You see leaks or hear unusual noises

An Annual Maintenance Contract is a yearly plan that covers scheduled service visits for your filtration system, so filters are changed on time and problems are caught early. See our AMC Plans page for what each plan includes.

Switch off the power to the system and close its inlet valve if there is a leak, then book a repair visit or message us on WhatsApp with a photo or short video. It often helps us bring the right parts.

TDS stands for total dissolved solids: the amount of minerals, salts and other substances dissolved in water, usually measured in parts per million (ppm) with a handheld meter.

TDS is a useful first indicator, but it doesn’t tell the whole story. It says nothing about bacteria, and two samples with the same TDS can contain very different things. That’s why a proper water test is the best starting point before choosing a system.

Different water needs different treatment. Water with high dissolved salts usually needs reverse osmosis (RO), while water that is already low in dissolved solids but may carry bacteria may be better served by UV or ultrafiltration. Testing first means you pay for the right system, not the most expensive one.

Water quality can vary a lot between neighbourhoods and even between houses on the same street, depending on whether the water comes from a municipal line, a bore or a tanker, how deep a bore is, and the condition of pipes and storage tanks. Results from next door are a guide, not a guarantee.

Boiling kills most germs, but it doesn’t remove dissolved salts, heavy metals or chemicals. In fact, as water evaporates the dissolved solids become slightly more concentrated. Filtration and boiling solve different problems.

RO removes most dissolved substances, including some minerals. Many RO systems therefore include a mineral or alkaline stage after the membrane to add some back and improve taste. We can explain the options when we recommend a system.

• RO (reverse osmosis) pushes water through a very fine membrane that holds back most dissolved salts, metals and other contaminants. Suited to water with high TDS.
• UV (ultraviolet) treats water with UV light to inactivate bacteria and viruses. It doesn’t remove dissolved substances.
• UF (ultrafiltration) uses a membrane with larger pores than RO to remove particles, cloudiness and many microorganisms, without removing dissolved salts.

Many systems combine these stages. The right mix depends on your water.
