When sending aquarium equipment in for repairs, be sure to clean and dry it prior to shipping it off. This is just a common courtesy for the vendor or manufacturer that you are sending the item to. When a manufacturer or authorized distributor gets the equipment, they don’t want to waste a lot of time cleaning it before fixing it and shipping it back off. They want to find the problem and fix it or replace the item so they can move onto the next customer. Also, by shipping an item wet, you run the risk of damaging it even further. The electronics in a completely unrelated part of the item can get wet, forcing you to have to pay for even more replacement parts or having to get a whole new item altogether. So, if a piece of equipment starts acting up or it fail, take the time to clean it up before sending it off.
