Booster Pump Issues

[Fringe09]

Hi guys,

Brand new SpectraPure MaxCap 2:1 Manual Flush 90-GPD RO/DI and Booster Pump Kit.

Pump does not turn on unless I bypass the pressure switch. When bypassed, pump turns on but the pressure is the same as turned off which is around 20psi. Adjusted the pressure on the pump but makes absolutely no difference.

Below are a few pictures. What am I doing wrong or what part might be faulty? I have reached out SpectraPure. Waiting for a response.

My switch is connected after the membrane, u want the pump to create a pressure differential across the membrane so water from the filters go to the pump then it is pushed through the membrane then to the DI exchangers, the switch is located upstream the Resin but downstream the membrane.

Not sure if it matters, but do you also have a SpectraPure RO/DI? The instructions from SpectraPure is before the membrane and after the ASO valve, unless I misread it.

Here is the manual.

Did you try switching the leads to the switch??

This will not matter its the same 12v power lead, the switch just interrupts the power to the pump.

Yes, I moved it to the empty the tab and the pump started, but did not turn off when I stopped the flow of water. Even when the pump did turn on, the pressure did not increase. Stayed at 20psi, like it was turned off.

This is what I was instructed to do with mine when I had an issue. I also have a spectrapure with the booster pump.

Bypass the ASO valve and see if the pump runs.

I can't tell exactly what I need to change.

Look at theASO valve , it is directional , make sure it is installed correctly.

I'll take a look shortly and will bypass it to test. The ASO valve was preinstalled when I got the unit.

They do make mistakes too , mine came without the carbon filter installed! there should be some arrows on it showing flow direction.

Let me get a better shot of it ...

I believe there is also a YouTube video that walks you through it.

Bypassed ASO, pump did not turn. ASO is connected in the right direction.

Possible faulty membrane?

 

[Fringe09]

Did you switch the wires going into the pressure switch?

What is frustrating is even when I bypass the pressure switch, the pump turns on but the pressure does not increase.

 

[120reefkeeper]

Did you try adjusting the pressure on the pump?

 

[Dumaurier7]

Is the pump in and out connections ok? Did you turn the bypass regulator screws clockwise to increase pressure?

 

[120reefkeeper]

This little Allen head screw in the center is the adjustment for pump pressure.

 

[Fringe09]

Did you try adjusting the pressure on the pump?

Yup, clockwise and counterclockwise. Didn't even move the needle.
