Boston 02108 plumbing notice

Shower valve, diverter, drain, or enclosure?

Water delivery and water containment are different systems, even when the same shower triggers the symptom.

01

Keep these conditions separate

Keep these conditions separate

  • Delivery clue: flow, temperature or sound changes when a valve is operated.
  • Diverter clue: water continues from the tub outlet while flow is directed to the shower.
  • Drain clue: the receptor level rises or a nearby fixture gurgles.
  • Enclosure clue: water escapes a joint, door, curtain, threshold, grout line or wall surface during spray.
02

The decision boundary

The decision boundary

A drip from the showerhead while off, tub-spout leakage during shower use, unstable temperature, slow drain, wet wall, or water outside the enclosure should not be compressed into shower leak. Record the operating state that produces each clue.
