How do I raise the level of a round valve box? Are there extensions for the valve box?
gelect on Jul 17, 2017
BEST ANSWER: You can cut the bottom piece and place it over the pipe. If that doesn't raise it enough we have placed a second box over the first.

Do you supply the 107BC Standard Series Round Valve Box only? And does it match with the d109-gl icv cover?
James S on Aug 17, 2017
Hi. For some reason I have a 6 1/2 cover that the lawn mower broke. I have been unable to locate a replacement at Plumbing supply stores, Home Depot or Lowes. What do I do?
Louise C F on Sep 29, 2016
I only need a cover. Can you just sell a cover? My cover sits inside my valve box and has an overlapping lip. The outer diameter of my cover is 7" which includes the overlap (measuring across the top). The ring that comes down of this top is 6" in diameter and extends down about 1.25". Mine is green. Do have one?
