I hate Floodstop hoses
I will have to agree that the Floodsafe hoses are annoying and I would never use them again. Here is my experience.
Upon moving into our new home last year, my bro-in-law gave us his washer and dryer as he was re-married and didn't need a second set. I prefer braided hoses, and all that was at Home Depot was the Floodsafe hoses which I figured couldn't be all that bad. Upon hooking them up, I noticed how awful the incoming water flow was into the tub. I had to replace the water valve on the Whirlpool washer because it had been stripped previously to me getting it. Why do manufacturers use plastic nipples on the valves? It is just a problem waiting to happen, but that is another issue.
So, I finally put one of the older rubber hoses back on and, to verify my guess, I had a stronger water flow into the tub. Since one of the hoses was messed up, I left my machine hooked up with 1 rubber hose and 1 Floodsafe hose. I even removed the water low-flow piece that was in the Floodsafe line, and it only helped some.
Fast forward to last week when we had no water in our house, turned out the water main broke down the street and they were out there repairing it. I spoke with the foreman and he said I didn't need to flush my lines as i was the highest up the hill and he was going to open the lower hydrant. Well, the next day, our washing machine didn't let any cold water in. I could hear the solenoid trying to open, but I figured maybe some sediment either clogged the incoming filter on the cold side, or jammed the solenoid. After pulling the washer out of its hole, I then realized that the Floodsafe line was the cold supply.
I immediately realized the problem. With all the air in the lines from having the water shut off, the Floodsafe closed down when the washer solenoid opened. I shut off the valve, began to remove the hose and heard it release the vacuum (of course I am having to lean all over the machine to get to the valve in the wall. I hooked it back up, turned back on the valve and turned on the washer, and it did it again. It took 3 repetitions to finally get it to stay on because at any point when another air pocket came through, it shut down the Floodsafe hose.
Needless to say, I am going to be removing the Floodsafe line and going back to a regular braided hose. This thing has been more frustrating than I could have imagined. But, if it were to prevent my house from flooding, I might feel different, but at this point, I am not feeling that way.
