I dont know if my problem is an isolated problem, but i ordered 2 air cut off valves from them on the 1st. The website said that they should ship within 5-7 business days. On the 14th i wrote them an email and asked when my parts would ship never got an email back. So on the 18th I called them(by the way there hours suck mon-thur) and it turns out that the parts I ordered are on backorder, nowhere on there site did they mention that the parts were on backorder. They said they SHOULD be getting the parts in 7 days so the 25th. Well I am on day 21 and the parts still have not shipped. Lets hope they actually ship on the 25th either way i will be sitting at almost 30 days for parts. So right now I dont think i will order anything else from them, and just hope that i actually get my parts.
