    I am putting new hardware in my shower/tub but the previous was kohler and apparently it’s not compatible with what I bought (American standard Rumson item 1005437741). Is RU101 the correct valve? Thanks

          Hi, after installing this valve I have low pressure and volume to shower head and spout, is there a way to increase the pressure ? The pressure and volume in old shower were good at head and spout and pressure in house is very good in all other faucets

          Hello Sam4dpd, Thank you for reaching out to American Standard. I’m sorry to hear of the issue you have had with your American Standard RU101 . I know that situation can be very frustrating. There isn't a way to increase the pressure but there may be a problem with the pressure balance cartridge.
