This is a type of check valve correct? The ability to take the lid off serves what purpose? Could you run a snake down the line with the top off?

Yes, this valve prevents water/sewer from backing up into your house; for example, it can be used to protect you from the city sewer backing up into your home (if you live in an area prone to that)...or, it can be used between a septic tank and the lateral lines to keep excess rain water in the lines from backing up into your septic tank. The lid is removable so that you can inspect & clean the flapper, etc. The flapper is also typically removable. One of the best inventions ever !!

No, you will be able to fit the snake down around the stopper. It's a very convenient product to use

You just drop the metal end through the barrel and then pull the snake through. You can put a few drops of oil on it but that's probably not necessary. One pass through usually does the trick for me.

Its a Screw on lid. Very, very tight, and the hinged cap for the drinking hole is tight as well. You could probably drop this from 10 feet and it wouldn't leak.

Hiya, it is a squeezy bottle if this helps. If you take the entire lid off, you could turn it upside down and let it drain out too.

This is a rectangular box as shown that is open on both ends. The trap itself is the sticky paper; the box simply keeps the sticky surface clean until something enters the box. I caught a 2 foot long snake in the trap and he struggled hard enough that he and the sticky part of the trap came out of the box. It was pretty evident that I had trapped something. I am certain that one could rig up a device as you suggest, but this would add a mechanical device that may discourage a snake from going into the box.

I've not had a reason to take it off, but I did examine the handles hardware and believe I know the approach. When looking at the handle itself and the hardware attached, it appears the chrome buckles snap down on the apposing sides of the handle. I suggest putting a flat piece of metal under the screwdriver you will use to pry up the ends, so you won't damage the top of the wooden lid.

The purpose of the valve is to prevent back flow into the house...it is a one way valve so it cannot have flow in both directions.

I didn't buy the check valve for a pump such as you appear to be using. What is the purpose of the pump and why are you concerned about back-flow or back-flush?

That special removal tool that you would need is actually visible in the picture of this valve. It is a "C" shaped ring that is next to the copper-colored end and can be slipped on & off from the side. This will be as easy to remove as it was to install, but I doubt that I'll ever have to remove it.

The lid screws on, but it leaks terribly. Skip the Tervis and get a Camelback instead.

This is a screw on lid & it is very secure & leak proof. Package directions state to remove/replace lid while in the "open" position.

you can remove the straw from the lid, but the bite valve is built into the lid so you cant use the straw by itself with the lid on.

Not quite sure as the valve has never been a problem. I have had problems with the lid releasing pressure around the perimeter since I've owned it. Sent it back once now the company wants nothing to do with it. Sorry! Rjl

Good Question. It is NOT a threaded screw-on lid so the whole metal top does occasionally come off when I try to pull the plastic lid cover off.

There is a check valve though just a ball with a spring holding pressure on it dont know how much pressure it would take but I don't have any pressure in my system when unhooking just the pressure in the feed hose

It has a check valve so that when the hose is disconnected, any water pressure in the inside line will not be released through the valve. This allows me to tee the external water source with the onboard pressure pump water line to the sink faucet in my camper. The fitting does not qualify as a backflow preventer for the water supply line since it is not equipped with an anti-siphon valve like those which should be either inherently built in to the hose bib or added on as an accessory before attaching the hose to the water source. Hope this helps.
