Pressure Regulator Malfunction


  • House - Poly Butylene w/ copper rings and fittings - no problem in 15 years.
  • City water
  • Watts Regulator mounted vertically originally (instructions say horizontal)
  • Over night 60 psi leaks up as high as 130. When used, goes back to 60 immediately and creeps up again over 6 hours or so. Originally noticed because gas water heater was lifting pressure relief valve.
  • Replaced 3 times from Home Depot w/ new Watts.
  • Is this due to the mounting? We don't have noticeable sediment.
  • The distance I have to change to horizontal is the length of the regulator, meaning I will have to go 90 out to regulator, then 180 back and 90 again into the house system. Alternative is to use big loops of copper to avoid the 90's.
  • Suggestions? I'd love to find an answer without all the new plumbing - especially if there is something else wrong.
    Thanks!
    Harvey - Norcross, GA.

Check the expansion tank on the hotwater heater , the bladder is probably rotted out.
