I wrote this to provide instructions on how to easily and inexpensively repair a Purewick Dry Dock station once the pump has failed or is not working at full strength. You only need to purchase two items-a new pump and a length of plastic hose. The fix should be done in less than 2 hours if everything goes smoothly and future repairs (if needed) will take minutes.
It is important to note, even if the pump is still working one of the rubber ballasts inside the pump may have ripped. This would mean the pump is only running at 50% capacity at best. I found this out when I removed my pump after it burned out. I had noticed a different sound for a couple months and it must have been running at 50% for quite a while.
The Purewick Dry Dock is powered by an inexpensive aquarium vibrator air pump. When I discovered this is the component used in what is supposedly a medical device, I was shocked. Add that to the fact Liberator (the only supplier) charges a couple hundred dollars for the Dry Dock station and everyone should be outraged.
I used to have an aquarium and used these types of air pumps. They would always burn out after about a year or so. Therefore it is not surprising they would quit after a few months of hard use. Aquarium air pumps are designed to push out air and not suck air in. In order to use these as a suction pump they have to be used in a manner for which they were not designed. In all probability this causes far more stress on the pump than it was designed to handle. Nevertheless, because aquarium pumps are inexpensive, replacing the bad pump with another is an easy fix and should last for quite a while. Plus, once the fix is done, it is a matter of only a few minutes to replace the pump in the future.
If my unit is like most, if not all, of the other Dry Dock stations, these instructions will be an easy step by step procedure. Any differences in design should be minor. My unit was made in 2018.
Once the repairs are complete, I chose to keep the replacement pump external to the Dry Dock station. If you choose, you can install the pump inside the unit and connect it to the switch. That will require extra work and something I choose not to do at this time. Leaving the pump external does have advantages such as being able to see the tubes and replace them easily if needed.
The tools required are as follows:
1. A couple Phillips head screwdrivers
2. A Torx screwdriver (these have a star designed head)
3. Box cutter or other sharp cutting device
4. Electric drill (3/8" or better) and drill bits
6. Duct Tape (maybe)
