Running two RO/DI units? One booster pump?

[glarior]

Re-doing my ro/di setup and can't remember how I had it setup before I moved it.

Ill post pic in a bit.

SpectraPure Max Cap 180GPD w/auto flush.
Bulk reef supply 150gpd 3 stage plus extra unit. Basically makes the same as the SpectraPure setup.

One booster pump.

Is there a way I can use the booster pump for both of them? I can't find an old post I had discussing similar issue. There was a way I set everything up and was able to boost pressure to both units making 300g per day.

Suggestions on hook up?

Just put a push connect 1/4" splitter on it with a valve so you can use one or both at one time

That looks like an Aquatec 8800 pump - you'll be happy with the performance of that pump as long as you are supplying no more than about 150 gpd of of pressurized water. So as long as you have four 36 gpd membranes there, you can make it work. Otherwise, get another pump, or jump up to a beefier pump.

Why 36gpd membranes? Saying the pump can not supply enough water/pressure for 75g membranes?

Also, I did decide to run the units separately. Have to replace all filters and will get another pump.

36 x 4 = about 150 - that's all that pump can handle.

Good to know. Thank you.

And in order to get decent pressure with a 150 gpd worth of membranes you'll need to over-restrict it a bit. 120 gpd is it's factory spec max.
