Do in need to replace my Febco 765

I bought a house with a irrigation system which was completely destroyed by way of not being winterized for few years along with damage from needed excavation work. One of the few remaining useful items is a Febco 765-1 PVB. I'm estimating that it sits about 4' lower than my highest sprinkler head in the back yard. Do I have to bite the bullet and replace it with a Reduced Pressure Backflow Preventer?

Right now the PVB is outside. If I go with a R.P. unit, should I install it indoors to protect it from the winter?

You could always raise the PVB five feet higher, and gain the elevation it requires. :thumbsup:

Thanks wet boots for the reply. Problem is that the pvb is on the front of the house. To raise it up that high, it would be above any shrubs. To add to that, i have decided to go with a fertigatioan system, which I think pushes me towards a rpz.
From reading your past posts, I know you're not a fan of indoor rpz's. Though not ideal, I was thinking of mounting the rpz indoors in the basement, to protect it from freezing. If I left the PVB outside, and had the rpz before it in the basement, would that cut down on water spitting out of the rpz?
