Plumbing question

I removed the valve by cutting the 2 lines in the basement and making a U turn with 2 Sharkbite 90s, then added Sharkbite one way flow valve in the line just behind the service center. Here are the links to the parts from Amazon:

$30 to not worry about it and an easy job!

I put a brass check valve that they offered on Amazon and paid $51.00. I think the shark bite check valve that Rick put on will work just fine. It is too bad that Keystone won't step up to the plate and install a good check valve. That plastic one they have sells for around $34.00, ridiculous price. It is really important to have a check valve on it or if you do bypass it make sure you put a external vacuum connector on your hose.

i'm confuse here why do i need a back flow on the fresh water line when the hose that i use to flush the black tank is not connected to the fresh water line? second if i take out the valve under the sink still i got the breather in the roof right?

The flush hose is connected to the fresh water faucet. Although very unlikely, under certain conditions it is possible that, without a backflow preventer, water could be siphoned from the flush line back into the fresh water source.
