Why buy a prefab Pure water system ? DI tanks rental is the best way to go


#1

There are so many systems available that are so complicated and expensive, when renting a di tank is cheap and very efficient. There are these guys making videos showing the use and versatility of these Pure water systems knowing that they are supported by the companies manufacturing them.

Why buy a Pure water systems made by WHOMEVER when you can get a tank for $50 and a hose that does the same thing ?

This is a question looking for feedback and to create a discussion.
Thanks

With the amount we use it the down time driving to exchange tanks wouldnt be worthwhile.

We usually have 2-3 guys working WFP on a site 3 sets of tanks would need 3 separate water connections.

Many locations with low water pressure would need pump to be added to a simple Di rental.

I don’t think the system’s out now are complicated by any means, they are simple systems.

I use only Di because most of my water is around 120tds or so. Being strictly residential and mostly solo I only use it a few hours a day, 2-3 houses, an hour on each house Everything I have read though says that in the long run ro./di is less expensive to operate. Most of it depends on how frequently you use wfp. I have thought of going to a double di system to extend the life of the di, but even the simpler ro / di systems seem complicated to me.

We rent. When we need new tanks our service just delivers them. We run 2 tanks on each truck with 3 hose reels. One with 3/4" for the tap and 2 others with 300’ of hose for the poles. Since we use trucks, did tanks more sense than a large system with a holding tank. If we were using vans, I think we’d go with one of those large rhg units that can run 2 poles. We like the tanks because you get the full tap pressure through them. With most systems, they also have an ro component so you’ll potentially need a pump on most jobs. But for commercial accounts, there aren’t enough if any electrical outlets to plug into, which could leave you unable to complete certain sections of a property. To be fair, 300’ of hose handles about 90% of our jobs and we don’t have to move the truck, but we do have some large jobs where we do move the trucks to reach other parts of the job.

So that’s why we rent. We do have some ez pure carts too though. But we mostly use those when we have a courtyard on a property and we can’t get hose from the truck to the courtyard from the outside of the building. We don’t want to pull hose through a lobby.

One other thing. Renting does become expensive if you start running multiple trucks. We need a total of 12 tanks on hand total. So theres a monthly rental fee and you have to pay an exchange charge when swapping.

So in the long run, owning a system is cheaper. But for us it’s not about cost, it’s about our use cases of rent vs own. I don’t think framing the conversation around what’s cheaper is the right way to go.

My tds is 750+ sooo…

I yet to have one but renting seems like it would be just another step to worry about. The systems don’t look complicated and I don’t think it would be much to take care of. But, that’s biased because I haven’t done neither. Plus, like others said, DI is limited to TDS amounts

Ro/DI sytems are simple, people are afraid of new things.

Both need to check tds at times, when needed, you exchange rental unit, a system you change filter onsite taking few minutes.

My systems have built in tds meters, checking tds is push of a button. Connect water and go, nothing else.
