Question about RO/DI 150GPD and Smart Buddie RO/DI

[t.mehoves]

I currently have '7 Stage PRO Plus 150 GPD Water Saver RO/DI System' and wish to add 'Smart Buddie RO/DI Booster Pump - For 50-100 GPD Systems'.

What do I need to change to accommodate the Smart Buddie? I am currently at around 40-45psi and I use the float valve to fill a 44g Brute. I am not too worried about losing 50GPD changing something out, just not sure what to change. I just don't want to replace the Smart Buddie every year or whatever may happen if it's not rated for it. Am I just overthinking this?

Bump

Did not see post. The Smart Buddie 50 -100 will not work properly long term with a 150 GPD RO system. The pump and flow restrictor is not setup for that size membrane.

We did release a new Smart Buddie 150 that will work for that size system.

If you want to email me at [email protected] I could send you additional information if you would like.

You could contact @AquaticLifeProducts like mentioned above for the bigger pump, or remove one membrane, and use the 50 to 100GPD pump(removing 1 membrane reduces the GPD down to 75 effectively negating the "water saver" portion).

Correct.

The water saver portion is kind of tricky. So by adding an additional membrane to an existing system without the Smart Buddie you increase the filtered water flow but keep the original RO systems flow restrictor. So you reduce your waste water to filtered water by half.

With the Smart Buddie we are already reducing the flow restrictor to 300 ml on the 50 - 100 Smart Buddie which is reducing the waste water too.

So if you add a water saver membrane and use a 300 ml flow restrictor you are double dipping. Additional membrane and half the flow restrictor size. This would likely give you a ratio of 1 gallon filtered to less than 1 gallon waste, possibly way more. It likely will scale the membrane as it is really hard on the membrane.

Sorry for the late response, I did end up purchasing the 150GPD Buddy off Amazon. I did not see it on BRS or amazon before making this post, so assuming it's new.
