How often should you replace your entire RO DO system, not just the carts?

[Gatorpa]

Been using mine for about 20 years... replaced a couple of filter containers that cracked over time, but that's it.

Same here
replaced cartridges, And RO membrane. Thats all

Funny that the same people that promonte not using a product like polycarbonate due to its durability/longevity also promote "bio-degratable" polymers for their "eco-friendly-sustainability.

Which is better: a single product that should last a lifetime or the same equivalent product that last a few years and still winds up in a landfill many times more over a lifetime (I
Won't even include the lmpact of manufacturing).

I'll choose the quality product that is designed to last over the disposable one that is designed to fail all day every day.

Electrolytic capacitors have the same issue. They do not last near as long as they used to. The electrolyte used in them has switch to a more environmentally friendly formula. I still see units made in the 1930 and sometimes older that still have their original caps and are still working. I see units that are 7-8 years old the the electrolyte is leaking out and corroding the copper traces on the PC boards. It also didn't help that some employee at Matsushita took off with their recipe to another company but unknown to the employee or the other company a key ingredient was omitted from the one they took. The caps made using the recipe would only last 3-4 years and fail. That was several years back now. They ended up in a lot of different brands of electronics. The also had some where the seals would fail prematurely where the wires were exiting the caps.

I tried to tell someone the other day that my 16mpg truck from 1988 is more environmentally friendly than his Tesla... That one flew right over his head...

Well, hammer debate here.....

If i buy hammer, then after one year i broke handle, replace it, then i broke head, replace it, then again replace handle....

But, whole time, i keep original screw... Is it the same hammer that i purchased years ago?

Same as rodi unit. U replace cartidges, at some point, you replace membrane. Is it same rodi just because u keep original housing for years?

Rodi is membrane+cartridges. Replace all, and... New rodi?

I asked the person (seller) why that is. He said the material doesnt contain preservatives. At least appaerenly the ones he's selling. At this point i'm not going to say which brand this is in public, it's pretty popular.

Why not say who it is? If they have good reasons for there product being the way it is, then let them come explain.

I certainly can't think of a good reason to have a piece of equipment that carries pressurized water with components that are designed to fail that quickly.

Whats the use in having a forum to talk about this stuff, if you can't call bogus products out?

100 psi going through your house ,pipes are eventually going to burst everywhere never mind your rodi.. i mean im sure it can handle it but long term use probably not a good idea . Get a restrictor installed on your main water supply . I had 85 psi going through my unit before my restrictor you do make water faster though lolol

 

[elysics]

You might sterilize the pipes and housings after that many years if you haven't already, but other than that, if it doesn't have cracks and the holder isn't rusting away, why buy new?

Is this a hobby specific salesman or a generic RO one? Of all the salespeople you shouldn't trust, the generic RO people are pretty high up the list with their pseudoscience water magnetizers and crystal healing filters and whatever.

 

[homer1475]

Mine is coming up on 20 years old. Sterilize once in a while, replace cartridges when needed, replace membrane every few years.

Still works just fine.

I would be super curious as to who this person was, and what company they work for? They are just plain wrong.

 

[Brett7397]

I'm told I need to replace my entire system every 7 years because it degrades over time? Do certain brands have a higher 'shelf life' than others? And I mean the actual unit... the chambers, valves, etc.
TIA

I would use the RO membrane until the tds starts to increase.

75 psi is what I have for pressure. My sister couple miles away 100psi. My previous ro/di unit I had a 125 psi pump on it.

 

[Brett7397]

I average around 80 psi and with that I can make 5 gal of RO water in 45 min with a 100gpd membrane.

 

[DOJOLOACH]

Debatably i would swap new ro push fittings, on pressurized lines only
