Should I replace???

I am ordering a new spirovent and going to install due to mine leaking. I know they can be cleaned, but I do not want to take a chance and take it apart and have it not work at all and be out of hot water for days waiting for a new one.
While I have it apart should I replace the backflow preventer and pressure regulator/ fill valve, or would it be a waste of money. They seem to work and the replacement would be preventative only, cost would be $100. System is 8 years old.

Some reducing valves, B&G in particular, have a screen in the bottom which is removable for cleaning. If yours does, I suggest taking a look at it. If the screen looks good, chances are so is the reducing valve. Most backflow preventers can be taken apart for cleaning, inspection, or rebuilding.

Good deal I will save the $$$ and just clean them when I disassemble.

Make sure you FLUSH! the incoming water supply to get all the crud that got dislodged from disassembly out... wouldn't want that stuff in your newly cleaned out valves.

If your water tends to have particulates (sand, rust, etc.) you could add an inline filter ahead of the backflow preventer. These are available at any home center and easy to install in most cases.

I already have a particulate filter on the system and the filter change is monthly. I think I will add another, but I will probably add it near the inlet so it does the whole house. 2 should be better than one. Can I soak them in some mineral spirits or something to help clean them.
