Are K-Valves difficult to install?
Not at all. Just hemp them up and insert them into the bottom of the drone stocks. Just remember to make sure the adjustment thread is tucked inside the valve so it doesn't catch in the hemp.

Are they hard to adjust?
The K-Valves were designed to be easily adjusted once installed. All you need to do is pinch the adjusting screw from the outside the bag and give it a twist. There is no need to re-enter the bag once the valve is in place.

How do I balance the valves so they all open at the same time?
After the K-Valves are installed, remove the drones and blow up the bag slowly. You should be able to hear when each valve opens. To add more tension to the valve, turn the screw out. This will change when the valve opens. Once you have the valves adjusted as you desire, put your drones back in and strike up your pipes. Instructions are included with each set of K-Valves.

Do the K-Valves ever need to be serviced?
The K-Valves were designed for long and rugged service, but they are on the inside of your bag. When you clean the inside of your pipe bag you should remove the K-valves and the hemp on the valves. Rinse them off with  a very small amount of soap and water and rinse completely.

I have the Ross Canister moisture control system installed, can I still use  K-valves?
Unfortunately, the K-Valves will not work with any moisture control system that covers the bottom of the drone stocks.

I don't have a zippered pipe bag. Can I still use K-Valves?
Having a zipper in the pipe bag does make it easier to install K-Valves, but you can still use them in a non-zippered hide pipe bag. You will have to remove a stock to install them and re-tie in the stock.

I have a split-stock tube type of a water trap. Do I have to untie a stock to install the K-Valves?
Maybe not. You can remove the tube trap and see if the K-Valve body will slide through the wider stock. If it does, you're in good shape as the valve body was designed to fit through most split-stock tube type of water traps.

How long is the warranty?
The K-Valves are made from exceptionally durable delrin and are warranted for 6 months from date of purchase against defects in material and workmanship. Some pipers have been using K-Valves for over 2-1/2 years without any issues. Should you experience any problems with performance return the valve in question to me and I will repair or replace it at no charge. The customer is responsible for the shipping and or postage both ways.
