A flexible wafer probe for testing the level of dissolved solids in a water source and a method of use are provided. The probe may have an adhesive coating so that the probe may be affixed to a surface, such as the interior of a conduit. The flexibility of the probe may allow the probe to be affixed to surfaces of various shapes. The probe may have a low profile such that it does not impede water flow through the conduit. The probe may be provided in the form of a flexible, thin circular pad composed of three layers. The first and third layers may compose the outside surfaces of the probe and may render the probe waterproof. The measuring instruments of the probe may be affixed to the second layer and exposed to the water through apertures that extend through the first layer of the probe.

Flexible wafer total dissolved solids probe and methods of use thereof

A reverse osmosis water system including a housing, a reverse osmosis cartridge, an unfiltered waterline, and a blend waterline. The housing includes an inlet and an outlet. A medial waterline transports pretreated water to the reverse osmosis cartridge. An unfiltered waterline includes a flow restrictor. A blend waterline transports a blended water mixture to the outlet. The blended waterline receives filtered water at a first flowrate from the medial waterline and unfiltered water at a second flowrate downstream of the flow restrictor. The flow restrictor provides the second flowrate at a substantially equal rate to the first flowrate.

Systems for water blending control

Some embodiments of the invention provide a reverse osmosis water filtration system including a housing, a pre-filter cartridge, a reverse osmosis cartridge, and a post treatment cartridge. A medial water line transports a first portion of pretreated water from the pre-filter cartridge to the reverse osmosis cartridge. An unfiltered water line includes a flow restrictor and blend valve. The unfiltered water line is fluidly coupled between the medial water line and a blend water line. The blend water line receives filtered water at a first flowrate from the reverse osmosis cartridge and unfiltered water at a second flowrate from the blend valve. The first flowrate and the second flowrate are substantially equal to produce a consistent total dissolved solids value.
