Hi there …
I think the deciding factor should be how much you intend to use Pure Water and your Water Fed Pole. With ‘Built to Last’ in mind, think today, and 5 years time.
The IPC Hydrotube is better suited to you if you are thinking irregular work. Any system with proprietary filters is better suited for semi-industrial use. Take a janitorial application - the frequency of filter change is low, and the Operator is not going to want to refill canisters etc. He is happy for his boss to buy insert modules and he simply changes them out once or twice a year.
Take that same system to full-time industrial action and you are very quickly going to pay the difference between Hydrotube and Wash-iT PRO in your refill filters. This is the principle of Price vs Cost. Hydrotube is a lower price, higher cost unit. Wash-iT is a higher price, lower cost unit.
We have designed Wash-iT PRO for international sales - you can buy all the replacement filters and media locally without paying a premium for brand. This will suit you with the Carbon and DI filters.
Again - for industrial use, you want a serviceable unit - and Wash-iT PRO is designed with DRAIN, AUTO-FLUSH, and DI FLUSH. This means, especially in hard water areas that scaling is going to be minimised.
If you are cleaning to 45ft, it is unlikely that you will be able to do that direct from an RO (any RO) without a pump. If cleaning to 45ft is not a high percentage of your work, switching to DI ONLY for the 4th floor is a simple and cost effective solution. For an idea of running cost during DI operation, simply divide your TDS by 100 ( TDS÷100 = $running cost of DI ONLY per hour). This is cheaper, faster, more convenient than lugging a pump and battery around all the time just for those few jobs. Of course, you can add a pump in front of Hydrotube and Wash-iT PRO.
Right now, if you are quick, I see that Wash-iT PRO is 10% and free delivery in USA! - I would call Alex and cut a deal!
By the way, Wash-iT PRO is only 30KG …
We are in the process of developing a number of add-on modules for Wash-iT PRO - they are all Work-in-Progress - but you have not seen the full kit yet. One day, you will have a detachable hose reel, an upright mount bar for fixing in your vehicle, a Pump Module, and of course, a Reach-iT pole holder …
That said, again, if you are not planning to be such a regular user, the Hydrotube will suit you really well.
