Default For Those of You with Cooler MLTs...

I put together my cooler MLT last night. After tweaking with it a bit, it works flawlessly...no leaks, etc.

However, the valve is so stiff that I have to physically hold it or the plastic supporting it will bend (not permanently, but the fairly thin walls of the cooler don't have enough strength to stand up against the force required to actuate the valve). Nothing dramatic, of course, but the basic point is that I have to hold the valve when I'm opening or closing it.

For those of you with a cooler MLT, is this fairly normal?

Just used mine for the first time yesterday.... Had to hold the valve also or the cooler seemed to 'flex'. Not a big deal... I doubt it will break or leak but, for the first time I was really paranoid.

nope , mine is easy. Are you using a ball valve?

I can open mine without holding it if I want to; the plastic does flex a bit but not enough to concern me in my case. I typically hold mine just to be extra careful.

It's a ball valve. The force required to open it isn't so much that it requires a herculean effort, but it's stiff enough to cause the cooler to flex, as the others have said. Just wanted to verify the cooler I'm using is up to the task -- seems as though it is.

Mine bends a little as well. I just hold it to be safe.

I Never had the Problem How Ever Have Known a few people that have had the Stiff Problem with the Ball Valves. They Took some FDA Approved Lube (Keg Lube) and took a Q-Tip or something to reach the Ball when closed and put a small amount on it, which helped it out a bit.. Worth a try perhaps!

Mine used to be tight, but it isn't anymore... and it leaks now too. I just hold the valve body while turning the operator. You're supposed to do that for "proper" (read Navy) valve operation anyways.

My old cooler mashtun used to flex a little when I turned the ball valve, but the new one doesn't. I found that putting a washer on the outside of the tun stiffens the connection and reduces (eliminates) the flex. Pics and details here: Wade's Homebrew: New Mashtun!

Mine flexes as well. I put big steel washers on the inside and outside of the cooler for a little reinforcement.

I used these valves for other thing. They will loose over time.
