1 in. Lead-Free Brass MPT Dual Check Valve is rated 3.4 out of 5 by 5.

Backflow Valve for a clothes dryer 3/4" cold water hose using for the dryer's steam options. ( spring loaded, resilient seated, dual check valve req'd for the dryer hose) Use Watts LF7R dual check valve Size 3/4 x 3/4" U2 x 2 Ser: 1211 W ASSE 1024 and 2 male brass adapters (screw adapter into valve body with 1/2" nylon tape wrapped 5 times clockwise to the adapter's end, do not use pipe dope) to mate with female hose connectors. Check sizing at a real plumbing supply store to check threading mates properly, and to keep overall size to a minimum. I then used the shorter stainless steel braided hose from the kit recommended for the dryer to connect from the cold water Y-connector to this double check valve. Let the label on the valve's body display toward you and the inspector; any orientation for the valve allowed. At the time of this writing the inspector had not checked my installation, having already paid the county inspection charge of $40. Total cost for just the 3/4" Watts LF7R valve with its 2 male adapters approx $45. Or pay the $140+ for the installer to do it for you. Need to replace every 5 years. If any of you have installed a Backflow double check valve using Watts or another brand that was approved by the plumbing inspector, add a comment, and tell us what brand and model used for the double check valve for the dryer steam hose. Enlighten us.

Rated 5 out of 5 by from check the pressure sometimes the cause of the squealing is due to high pressure. this can be resolved by installing a pressure regulator or adjusting the existing fully functional regulator to somewhere around 50 to 65 psi.

Rated 1 out of 5 by from Squeals when water flows.... Makes the worst squeal when small amounts of water flows. Not sure what to do after spending a lot on copper and brass fittings.
