booster pump, never had to use one before, my second to last lasted 5 years and gave me 002 up till the last point. everything the same, just maybe a different membrane.

when i restrict the reject water fully the psi meter goes up to 40psi never higher the n that in all its life does that sound right

thanks for fast reply

What is your tap tds?
Never fully restrict your reject water it will damage the membrane.
Run more water to waste.
