Ive always used this one in one of those integrated pump boxeshttp://www.ro-man.com/shop/index.php?route=product/product&path=28&product_id=84
I need a new booster pump tor my 450gpd RO system and i've lost confidence in my usual supplier their pumps seem to fail too quick if they work at all (mate of mine has had the same problems too)Anyone recomend a good pump rated at 100psi or so
