ValterraP23507VP Plastic Hand Pump Kit, White

The pump worked great with no issues, this was my first time trying to winterize my 33' rv. It took less than 1 gallon of antifreeze and I had pink flowing through every faucet and the shower. And it only took a few minutes at best, clean and easy.1 tip, I'm not sure if you would be able to actually "over pressurize" the pipes, but probably ease up when you start feeling a good bit of tension like your not able to pump anymore. Means you have to open more faucets. I accidentally pumped too much in, and when I opened every other faculty, they all just poured out pink.All in all, I thought the construction was pretty sturdy on this pump, and it really worked well and exactly as it was intended to.I can not believe how easy it was! 5 stars for that.Highly recommend.

I used it to pump antifreeze into my camper plumbing system. It worked great and only a few minutes. Hooks right to the place where you hook up the hose.

I added antifreeze to my Rv water lines. Per prior reviews I added hose clamps to the hoses before using.There are instructions included which were helpful to ensure everything was done correctly.There is some resistance and I had to press the plunger handle with some force initially but it worked out great.

Getting suction was a bit tricky but worked with multiple pumps. Hose would pop off randomly with too much pressure, it does work use a helper and put a hose clamp on tube to keep from popping off and soaking you with antifreeze.

Worked great.

You need three or four hands to make this work properly.First of all, it takes quite a few pumping motions to start the suction. And then, the black tube that attaches to the hose that sits in the jug you want to move liquids from keeps falling off, creating unexpected and unintentional sprays that land anywhere but where you want them.

Works great

Worked great. Had to secure clear plastic hose to pump. Other than that perfect.

Very good product for winterizing your campers..

Very useful to winterise my black tank spray unit. Easy to use and a surprisingly powerful pump. Reasonable price with quick shipping

Pour ma roulotte de camping

Works well so long as you can keep the hoses attached.I added plumbing clamps on both sides. on the pump side it help, but the outlet side did not. They use a sheer brass coupling rather then one with any sort of indent to grip the plastic. Could've been a great product with a few adjustments.

The hose falls off some times
