Boat Engine Flush Mixer Liquid Flow Valve for Salt Remover Solution Ideal to Flush Outboard and Inboard Engines Connects with Garden Hose, Spray Nozzle, Engine Flusher

All of these leak a little bit. Doesn't matter what brand you try. Might as well get the cheaper ones. I have a spare as well.

As others noted, this is a cheap option to flush a boat engine. However, my buddy bought the more expensive one and even that thing leaked just like this one...yet 3 times the cost. These are all cheap plastic with mediocre seals but, honestly, you are connecting a hose to flush the engine so as long as water is flowing fine and pushing the flush canister liquid through it is good. Water is going everywhere anyway so just be a little more careful not to have it soak your leg. I don't use it on washing down my boat but the same thing...you are washing your boat so if water leaks I am not really sure that is an issue...minus getting you a little wet. I say give it a shot and save the money from the other ones since the first time you drop any on concrete you will be buying a new one.

This thing leaks horribly and does not mix correctly with salt away mixes about 2parts water to 1 part soap. Don't buy for that purpose.

So far I had it for over a year and it has been great to me , no issues what so ever and can’t best the price

It works ok. Leaks a little

Quality seems good so far.

I bought this to add fertilizer through my garden soaker hose.......works great!!!!@!

Product leaks from every connection point possible. I use an expensive soap product and if half of that product leaks out then what good is the mixer doing?
