Streaks on a Tuesday, and a resin vessel that should have lasted longer
It is the middle of a round day and customers' windows are drying with spots. You check the TDS meter and the reading coming out of the pole is higher than it should be. The resin is spent. You thought you had changed it recently, but you cannot remember exactly when, and you have no idea how many litres have gone through it since. The afternoon is lost to going back to the unit to change it.
In the evening, you wonder whether the RO pre-filters were ever changed this year, whether the mains water in the area you filled at is harder than usual, and whether this vessel is getting through resin faster than the one in the other van.
Pure water is a production process, run from memory
A water-fed pole system is a small water treatment plant, and its consumables wear out based on how much water goes through them and how hard the incoming water is. Most window cleaners manage it by feel.
- Tank fills are not recorded, so litres through the system are unknown.
- TDS readings are checked but not written down.
- Resin, membrane and filter changes are not dated.
- The cost of consumables is in receipts, not linked to the work done.
- Two vans with different systems are managed the same way, or not at all.
How your system should be set up and maintained is for you and your equipment supplier. We deal with the records.
Lost afternoons and an unknown cost per clean
Resin that runs out mid-day costs cleaning time and sometimes a return visit to a customer whose windows dried spotty. Consumables changed too early waste money; changed too late, they cost more in call-backs. Without the figures, you cannot compare suppliers, see whether an RO unit is paying its way, or know what pure water adds to the cost of each house when you set prices.
Simple tracking for fills, readings and changes
We build a light tracking tool for your vans, used from a phone in a few taps.
- Each van's system is recorded: tank size, RO unit, resin vessel, filters, and the supplier and cost of each consumable.
- Fills are logged with one tap, with the litres, where you filled and the incoming TDS reading if you take one.
- TDS readings from the pole are recorded when you check them, so the trend is visible over days.
- Resin, membrane and filter changes are logged with the date and cost.
- The tool shows litres since the last change and the trend in readings, and reminds you when you reach the limits you set for each consumable, before streaks appear.
- Litres used are linked to the round days, so a monthly view shows the pure water cost per day and per house cleaned.
| Record | Today | With tracking |
|---|---|---|
| Tank fills | Not recorded | One tap with litres |
| TDS readings | Checked, forgotten | Recorded, trend shown |
| Resin and filter changes | Guessed dates | Dated with cost |
| When to change next | When streaks appear | Reminder at your chosen limit |
| Cost per house | Unknown | Monthly figure from your records |
Consumables changed on your terms, not on the day they fail
Resin and filters get changed at the unit, not mid-round. You know what pure water costs per clean, which feeds into pricing and into decisions about equipment. You can compare vans, suppliers and filling locations using your own figures. And when a supplier offers a different resin or filter, you have a baseline to judge it against.
A normal day barely changes: tap when you fill, tap when you check the reading. The tool does the arithmetic.
Do you manage pure water by feel?
- Resin runs out mid-round without warning.
- You do not know when filters were last changed.
- TDS readings are not recorded.
- You could not say what pure water costs per house.
- Your vans' systems are managed differently or not tracked at all.
