I have been quite disappointed in the quality of construction on the #300 brass valve recently. I had a brand new one today that lasted less than 4 hours before the innards spilled out somewhere between the greenhouse and my office.  Sad!

Hello Corey,

Thanks for your post. The #300 Shut Off has not changed in a number of years.  I suspect what has happened is actually the result of an intentional feature, not a defect.

We build our brass shut-off to be easily rebuildable so that growers can replace parts rather than replace the whole valve as components wear. The innards of the valve are held in place by the washer. This should keep the nylon seal secure as it is generally a tight fit.  After some compression, will will begin to flatten out and loosen up. I suspect that the washer was either missing or loose and this allowed the seal to fall out. 

To replace the ball, you would remove the washer and turn the handle to the off position and the ball will slide out as well.

We can get you replacement parts for the components that are missing. 

We will reach out offline to handle this.

I have three #300 valves, one for over a decade. Overall, these brass shut-off valves are simples, but highly effective. However, recently, two of them have begun leaking. One of them is only a year old and it is surprising. I thought a simple washer replacement would do it, but, alas, no. I think the material of modern washers may have suffered over the years. 

Even when I tighten down the valve, they leak. One leaks at the valve lever, and the other on the female end. I tried putting teflon tape on the hose as a last resort, and that didn't stop it either. The valve leaks on other hose ends as well.

Would a repair kit be effective on the two valves? The design is simple and that's what makes it so reliable (in my opinion). I have not found repair kits generally available?


I know this is pretty small in the range of sophisticated products you make, but it's the simple things we daily deal with...

Thanks, David

Hello David
Thank you for your post, the #300 shut off valve has not changed in a number of years now. I am sure that there are some changes from your original #300 shut off valves that are over a decade old but these are only minor.

It sounds like you have some ware happening either on the rear seal or the original hose washer, a standard generic hose washer is not quite thick enough to create a good seal between both rear seal and the male hose end.

It's always best to use original Dramm parts.

The internal parts for the #300 valve are replaceable, the #RK-BB is the full repair kit, includes the ball assembly and seals with a new handle.
I always recommend to check first but if these are not available through your local Dramm supplier you can call, place your order and have shipped direct to you. (920-684-0227).
