Sorry guys I have been trying to reply to your questions to me but for some reason the site was timing out when I tried to post. My internet has been acting up a lot lately so. But anyway
The only leaks I have seen were on my own house. My home has storm windows and some of the storms have drain holes, some do not. This is where the leaking becomes and issue. So I have decided that homes that have storms (most are a wooden type window by me), they dont get the WFP. Where I livem there are a lot of ranch homes, it’s nice in that their one level. But a lot of the two level homes here are older and have a wooden frame with storm so I wont WFP them. It kind of sucks. The system does save time and money when I can use it on a house. But like I said I am focusing on mid-rise. Thats the money maker here. Being I live in old people retirement land, there are a lot of mid rise doctors offices here. Many of the buildings have not been cleaned and you can see the dirty windows from a distance. But once again if the house has wooden widows I dont wfp. I can’t take the risk.
as far as the systems. Heres a link to them
Tucker has a simular system. The reason I say try these out is cause if you find they work and you want to move to a DI or RODI system, these WFP for both companies will work with a system. But right now from what I can see you use standard tap water from the customers garden hose supply with a tablet (soap?) The method is almost the same with a Di RODI system.
