Avoiding Potential Pure Water Cleaning Problems

Water Droplets

A Pure Water system can save you time and money, but there are a number of situations that can hinder your effectiveness.  Here are some problems to identify and avoid.

Improper Technique

One of the biggest problems facing window cleaners using their Pure Water systems is improper technique.  Like using a squeegee, there is a right way and a wrong way.  The right way will leave windows sparkling clean.  The wrong way will leave dirt and streaks behind.

Too Little Pressure

A Pure Water system is not about cleaning with high pressure, but you do need enough pressure to get the water up the length of the pole to where you need it on the window.  If you are working at heights over 30 feet, the pressure of water coming out of the tap may not be sufficient.  This height may require a booster pump.

Stubborn Stains

Pure Water cleaning in its simplest sense is just Pure Water and a brush, but some window stains need more scrubbing power.  For these stains, there are additional pieces you can use with the waterpole, including different types of scrub pads.  You can attach these with an adapter to use on the backside of the waterpole brush.

Dirty Water

Pure Water works wonders on dirty windows, but water that is not Pure will leave haze and streaks.  If you are not using a strong enough system, the water may not be Pure when it comes out.  Water with high TDS may require a more extensive filter system.  If your filters are dirty and in need of replacement, they also may not clean the water completely.  Make sure you are filtering the water sufficiently and keep your filters in good condition.

How To Make Pure Water

Dirty Water to Pure Water

Working in areas of low TDS? You can probably get away with just a DI resin system for filtering!

Different areas have different levels of TDS (Total Dissolved Solids) present in the water.  This level of TDS determines how much you need to filter the water to use it for cleaning windows.  Many areas of Michigan, for example, have very low TDS (around 125 Parts Per Million), and many of our window cleaners can therefore get away with a smaller, simpler system.

What kind of system do you need?  Use a TDS meter on the tap water to find out.

  • TDS of 150 PPM or less = DI resin only
  • TDS of more than 150 PPM = Multi-stage system (Carbon filter –> RO filter –> DI Resin)

The simplest Pure Water filtering system consists of just a DI resin canister/tank that water is run through from the tap to the tank to the waterpole.  This single stage filtering system can make Pure Water of most tap water, but when working with tap water of a TDS of more than 100, this system can become very costly and less time-efficient as the DI resin will be used up much more quickly.

To lengthen the life of the DI resin, the addition of RO filters and carbon filters can aid the process.

What are all these filters and what do they do?

Carbon Filter

Activated carbon

Activated carbon – per Wikipedia

In a multi-stage system, the Carbon filter comes first.  It consists of charged carbon and absorbs impurities to help the other filters do their job.  Think of this as a large sieve that captures larger particles.

RO Filter

A reverse osmosis filter

This is the second stage of a multi-stage system.  The Reverse Osmosis filter uses a semipermeable membrane to further purify the water.  It traps a large concentration of impurities.

DI Resin

DI Resin

DI Resin

The final stage in a multi-stage system, the Deionization or Ion-exchange Resin consists of charged resin beads that “polish” the water and complete the process of making it into Pure Water.  With a multi-stage system, about 80-90% of the impurities have been removed before they reach the DI resin.

Pure Water and Water Pressure

a stream of water

Low pressure performs ideally with a waterpole, because the goal is not “pressure washing” but merely agitating and rinsing away debris on windows.  You need only high enough pressure to push the water up the pole, though the brush jets, and onto the window to rinse it.  The brush and the reaction of the Pure Water absorbing particles are what clean the window.

Using a waterpole correctly with a brush and low pressure Pure Water leaves behind no minerals to create water stains.

Most taps can produce pressure sufficient to operate a single pole up to 30 feet or 3 stories in height (about 40 psi).  Some water pressure is lost in the filter process and some through the waste water (the minerals or TDS) expelled by the filters, but this usually leaves a sufficient amount of pressure to clean effectively.

Reaching higher, running multiple poles, or some cases of very low tap water pressure may require the additional help of a water pump.

So while many window cleaners working with smaller residential customers may not need the assistance of a water pump, it may become necessary for window cleaners running multiple poles and working on taller, commercial buildings.

Water pumps are most often used between the tap and the filter system.  This gives an extra push to water as it goes through the filters and may actually extend filter life.  It also results in a stronger pressure at the end of the pole, where it is needed most.

Pumps may be battery operated or plug-in and usually push 100 psi or about 5 gallons per minute.

Pure Water Versus Tap Water

Cleaning windows with tap water and a hose just doesn’t work.  Why not?  Because tap water has minerals in it, and those minerals leave a film and streaking behind on windows.

Think in terms of the difference between the regular rinse at the car wash, and the final “spot-free” rinse at the end.  Without the spot-free rinse, the water dries into small water spots on your car.  But the car wash filters the water for the final spot-free rinse to eliminate those spots.

Minerals present in tap water make up the water’s TDS, or Total Dissolved Solids.

Different areas have a different TDS levels, and this is because they have different concentrations of minerals in the ground, where rain water drains into storage reservoirs.

A TDS meter can test your water’s mineral concentrations.

(Curious about the TDS levels of your water, or a client’s water?  Check out this online map for a quick reference!)

Any amount of minerals in your water will leave a film on windows.  Spring water and mineral water from a bottle also have them in varying quantities.

Only Pure Water (or distilled water) has all of the minerals removed, and will give a TDS reading of 000 Parts Per Million (PPM).  Therefore, it leaves no residue.  In fact, Pure Water, in its attempt to return to its “natural” state (“dirty,” or full of minerals), will even absorb dirt and particles from the glass surface, leaving windows perfectly clean!

Pure Water systems create Pure Water from tap water through a process of filtering out the minerals dissolved in the water.

There are a few methods of removing minerals from the water that are combined in Pure Water systems – carbon/sediment pre-filters, reverse osmosis filters, and de-ionized resin filters.  The level of TDS in the water would determine how complicated a system would be needed to filter it into Pure Water (a TDS reading of 000 PPM).

Tap Water Versus Pure Water

4 Reasons to Switch to a Pure Water System

There are plenty of reasons that could be given for NOT switching to a Pure Water system for cleaning windows.  Maybe you have thought of some of them when you consider Pure Water.

But on the other hand, here are four reasons a Pure Water system could be very beneficial to your window cleaning business!

1. Customer Privacy

Because there is no need for ladders and windows can be cleaned from the ground, they are less intrusive, less invasive.  This is great for all customers – homes, offices, hotels, etc. – who can be guaranteed greater privacy.

This can give your customers a better peace of mind.

2. Safety

With a waterpole, you can clean windows up to 80 feet off the ground without a ladder.  This means better safety for window cleaners and less chance for property damage for customers.

New health and safety regulations are getting more and more strict about ladders – stay ahead of the curve!

3. Clean Greener

Waterpoles use only Pure Water and therefore they are free of soaps that contain various detergents and chemicals.  This is better for the environment and safer around children and pets.

The brush does all the scrubbing and then the Pure Water rinses it all away – leaving no residue!

4. Clean Faster

Pure Water systems clean windows “30% to 80% faster than conventional methods,” according to an article about selecting a Pure Water system on Pureglaze Window Cleaning Services.  This gives you the freedom to clean quicker, make more money for your time, and fit more jobs into your day.

Work smarter, not harder!

Pure Water systems require research and an investment upfront, but the benefits will far outweigh the cost in the long run.

The key is getting the right information and making an informed decision.
