Q:I work for P&G and we need to have backflow prevention in fast food restaurants that use our dilution centers. I cannot put these on the mop sinks, unless it can be removed sometime in the future. Is there a removal tool for this item? If it fails, how do we replace it?
A:Yes, this item is fully removable at any time since it is threaded, and has a gripping area for the tool, which is a common pair of plumber's pliers. If this item fails, it is simply unscrewed for removal and replacement.

Q:I just bought a house that has this device on the outside hose spigot. I'm getting very little water flow through it, just a trickle. Does that mean it needs to be replaced? Is there some way to get the water to flow through it at regular water pressure that I'm not aware of? Could it be clogged up by hard water deposits? If so, how to I clean it?
A:It sounds as though that this Backflow Preventer is either broken, or installed backwards. You can either replace this unit, ore just remove it completely. There really is not much need or use of one of these on a residence, unless you have a pool that you are filling that resides above the spigot.
Q:If this is designed not to be removed but designed to be feild tested and replaced if not functioning correctly how is it supposed to be removed?
A:This backflow preventer should not be removed, but can be replaced. Furthermore, you wouldn’t want to remove it and operate your equipment without it. You can replace the backflow preventer if it’s faulty. Just make sure to shut off the water source before replacing this part.
