Amado Water keys are the main water keys used on Thane trumpets. They are used because they are small, lightweight, only one small solder point, and work well when properly cared for.
Caring for your water key
Keep them clean! They are small and have tiny internal parts that will stop working if they get dirty. Flush water through them to clear out any blockage and add one drop of valve oil to clear up and prevent freezing up.
If you notice no water is coming out, or very little, that means it is dirty and there is something in the way. Take the slide out of the trumpet and plug up one hole with your finger, run the sink water through the open hole and open the water key. This will flush out any dirt and clear up the issue. *VIDEO TO COME*
If the key is frozen stuck. That means it was dirty and dried out. Put some oil on the piston and in the hole. Push the piston in and out or turn it if it can move. Hopefully it frees up enough to move back and forth. Once it is unstuck goto the sink and flush it out with soapy water. Then rinse with water forcing the water out the water key hole, then reapply some oil to the piston and work it back in. To avoid this in the future keep some oil on the piston part. *VIDEO TO COME*
Ideally when these get frozen stuck they need to be taken apart and cleaned from the inside. The spring gets dirty and the inside on the piston and barrel need to be cleaned and brushed out. If you don’t feel comfortable doing this yourself then take it to your local music repair place.
