A flowmeter includes a conduit having an elbow portion and a straight section downstream of the elbow. A turbine is mounted inside the conduit in the straight section adjacent the elbow portion. The turbine occupies less than the entire cross section of the conduit and is disposed adjacent the side of the conduit which receives the laminar flow exiting from the elbow portion. A permanent magnet is mounted on the turbine, the rotation of which is picked up by a Hall-effect sensor mounted in a cavity in a wall of the conduit.

A flow control valve controls a flow of water through a passage to a brine tank of a water treatment apparatus. A valve seat is between first and second sections of the passage. The valve seat has a first end with a concave surface facing the first section and an aperture extending from the concave surface to a second end that faces the second section. A groove in the concave surface extends from the first end to the aperture. A valve element moves within the first section in response to pressure of the water in the first section thereby varying the size of a path through the passage by an amount that varies as a function of the water pressure. The action of the valve element maintains a substantially constant flow rate through the flow control valve regardless of water pressure variation.

A water treatment system includes a tank that contains a particle bed for removing minerals from water flowing through the tank. The regeneration of the particle bed is conducted in response to measuring its conductivity. A probe is provided for that measuring. That probe has a sleeve with a tubular portion for extending through and engaging a wall of the tank. A probe body is removably received within an aperture of the sleeve and includes a pair of electrodes that project inside the tank. A retainer that secures the probe body within the sleeve. Different mechanisms are provided for securing the sleeve to the tank depending upon the particular materials used to fabricate the tank.

A home RO filtration system includes a membrane module having an inlet connected to a feed line, the membrane module also having a concentrate outlet coupled to a concentrate line, and a permeate outlet coupled to a permeate line. The permeate line communicates with a faucet. The system includes a flush reservoir communicatively coupled between the permeate line and the feed line. The system is configured such that after the faucet is turned off, a portion of permeate is delivered to the reservoir and then delivered to the inlet of the module to flush the module.

A bypass valve includes a body with first and second chambers connected by a bridge passage, an untreated water inlet and an untreated water outlet both open into the first chamber, and a treated water inlet and a treated water outlet both open into the second chamber. A first valve element is rotatably received in the first chamber alternately to connect the inlet to the untreated water outlet or the bridge passage. A second valve element is rotatably received in the second chamber alternately to connect the outlet to the treated water outlet or the bridge passage. A manually operable mechanism rotates the first valve element in the first chamber and the second valve element in the second chamber. A flow sensor is received within either the first or second valve element to measure the amount of water flowing through the bypass valve.

A filtration assembly includes a feed water line and a permeate line. A shut-off valve is coupled between the permeate line and the feed water line and operative to open the feed line when the faucet is opened based on a pressure differential between the feed line and the permeate line. An energy storage member is located within the permeate line and configured to compress and then expand after the faucet is closed causing the shut-off valve to fully close.
