- andrew sherret in langford
- emco water works in langford
- van issle, close to the mega wallmart DT --> page 21

thy have 1 1/2, so you might have to put a adapter in, but I would ask if thy could get a 1 inch
if emco has them but you cant buy thetre, let me know, but if thy have it you dont have to drive all the way DT
