FAQs

Common questions answered.

Five of the questions we hear most often on carpark and street linemarking gear. Full knowledge base on our FAQ page.

  • What does TDS meter measure?

    Total Dissolved Solids in ppm. Dip into rinse-water output. Pure RO/DI reads 0-5 ppm; tap water 50-200 ppm. Replace DI resin when output climbs above target threshold.

  • DI resin or carbon filter?

    DI resin removes dissolved ions (after RO). Carbon removes chlorine + chloramine before RO. Both are sequential stages of the full purification - need both.

  • Replacement interval?

    DI resin: TDS-driven (replace when output ppm exceeds target). Carbon: 6-12 months on standard tap water input. Sediment: 3-6 months.

  • What role do TDS meters play in maintaining my water filter system?

    Think of TDS meters as the fuel gauge for your water filter system. Their role is critical for proactive maintenance, saving you both time and money. By allowing you to instantly test water filter performance, a TDS meter gives you real-time data on the purity of your water. This is the only way to know for sure that your system is producing the spot-free water required for professional cleaning.

    The main role of the meter is to tell you exactly when your DI (deionisation) resin is exhausted and needs to be replaced. You simply test the water coming out of your system; when the ppm (parts per million) reading starts to rise above 10, you know it's time for a change. This prevents you from replacing your filters too early (wasting money) or, even worse, using expired filters that leave mineral spots all over a client's windows. Regular testing is a non-negotiable step for any serious professional wanting to protect their gear and their reputation

  • How do I maintain tds meters & filters for long service life?

    After each use, flush clean water through the system and wipe down external surfaces. Inspect hoses, fittings and o-rings for wear or cracking before each use. Change pump oil per the OEM schedule (typically every 50-100 hours for petrol units). Store indoors or under cover to prevent UV degradation of hoses and seals. For seasonal storage, run a pump-saver solution through the system to prevent mineral buildup and corrosion. Replace worn nozzles before they affect spray pattern — a worn nozzle increases water consumption and reduces cleaning efficiency.

TDS Meters & Filters

9 TDS (Total Dissolved Solids) meters and DI resin / carbon filter elements. The measurement + service stage of the water purification workflow - meter tells you when the resin is exhausted.

TDS measurement. TDS meter dips into the rinse-water output and reads ppm dissolved solids. Pure RO/DI water reads 0-5 ppm at the meter; tap water typically reads 50-200 ppm. Replace DI resin when output TDS climbs above the target threshold.

Filter element replacement. Tucker DI resin filter elements (100 mm dia x 762 mm long) standard. Carbon filter elements at the same dimensions for chlorine + chloramine removal. Replace at TDS-driven interval (DI) or 6-12 months (carbon).
