Willow Springs WSD6X300A PEX Tubing
Willow Springs was started in 1993 by Dan and Karen Higgins. Their first building was a garage attached to their home. The first products were outdoor wood burners. Product offering expanded as they added radiant floor, gas boilers, gas furnaces, mini splits, and much more. Through the years, they have worn the hats of a contractor, a wholesaler, a distributor, manufacturer rep, and now Willow Springs S.R.A.
