To prevent any back water from the shower head and also the water contamination into system.
A reduced pressure backflow preventer is used to protect the water supply from contamination by preventing water from flowing back into the system. It works by creating a barrier that allows water to flow in only one direction, preventing any backflow of contaminated water.
In plumbing, by using a device known as a backflow preventer. It only permits water to move in one direction.
A backflow preventer valve is used to stop water from flowing in the wrong direction in a plumbing system. It helps maintain the integrity of the system by preventing contaminated water from flowing back into clean water sources, ensuring that the water remains safe for use.
I guess I would have to say first what kind of back flow? There are lots of them. Then to answer your question has it been along time sense you've used this valve? If so there could be a smallest of chanses. In 20 years in my job I've never had this happen. But I guess there is always a first.
out of the over flow
Needle valve seat is more than likely leaking which will cause gas to flow into the cylinder and down into the oil. Drain the oil and repair the problem as this will destroy your engine.
i had the same issue some time back on a 98 Road King Classic. Ended up being the back flow preventer between the fuel line and the tank. i fixed my by removing the fuel line on the left side of the tank. this is very easy. move the hose out of the way. now the fun part. the back flow preventer screws into the tank. it can be accessed after the fuel line has been removed as described above. the leak could be coming from the seal on the backflow preventer or it may just need to be tightened. there is a special tool that can be purchased from harley but i made a tool by taking wood chisel and grinding the edges down to fit the slot in the backflow preventer (bp). be very careful not to compromise the threads for the fuel line. i took the bp out, put a new seal and then used some thread sealer. tighten the bp up, reinstall the fuel line and hope for the best. hope this helps. greg
