Fast
thank you so much supplyhouse for your speedy time in getting this item to us. We had no hot water in a covid-19 world and know one had this in stock. We were already without hot water going on 3 days and every place we looked up, was anywhere from 10 to 14 days or more. We ordered on a Saturday late afternoon, you said we would have it on Tuesday. We watched the UPS truck on the tracker and thought we would've gotten it by 1 it didn't get here until 630pm. It was the longest day! But got the item and it worked great and back up with hot water in minutes! Thanks again. Fast service

Product came broken
Product was damaged when it arrived. Trying to get ahold of these people is a joke. I attempted 3 times to no avail using their own system. Best bet , go elsewhere
