Waterdrop TSU

I decided that if we are going to go on a broader exploration of North America and leave the safety and quality of our drinking water in British Columbia, I needed a better answer for water on the trailer. Today I installed the Waterdrop TSU to solve that problem in our RV.

There are two ways to get water on the trailer, through the use of municipal pressure water, for example at a full-service hookup, or through use of both the pump and the fresh water tank. So far in our camping, including our 2020 adventure, we would fill a 2 gallon drinking water container, and store it in the fridge. I would make use of a lightweight Amazon inline water filter, on the pressure water, or we would directly fill one or two of the drinking water containers if we expected to be in a location where no water was available.

While the tank is fine for showers, brushing teeth, and I was sanitizing with a three stage (bleach, vinegar, fresh water rinse) process, I wasn’t super comfortable drinking out of that tank when I can’t see whats in it.

While there are plenty of multi-stage filtration systems on the market, the majority that are designed for RV uses sit outside the rig, either before the tank fill, or as an integrated part of the pressure water system. While the pressure water system is perfectly fine with an external multi-stage filter, we also wanted a solution for drinking water when the tank was the only option.

I chose the Waterdrop TSU, as it offers a three stage filtration system and for the following reasons:

• It can be installed under the sink. For us it was a tight fit, but we were able to get it under there once we removed the sink drain plumbing. Now that the unit is under the sink, the device is fully accessible, and I am able to remove all three filters. I don’t need to manage a large filter assembly outside the rig (and store it!)
• It doesn’t require power. This device runs on 3x AA batteries, primarily for monitoring the age of the filters that are installed in the unit.
• It provides a dedicated faucet. When we use this faucet, we know we are getting drinkable water, regardless if it’s coming from the tank, or if it’s coming from a pressure water system at a RV park.

With the new system in place, it provides us a large amount of space back in our fridge for a backup box of wine, or other more practical uses, and drinking water is something that doesn’t need to be managed as closely as we move forward.

So far I don’t have much feedback on the Waterdrop TSU. As a marine junky, my first choice was the Seagull IV, which would have saved some space – but after searching for options, the Waterdrop was well priced (less than 1/3) and offered optimal filtration through a three stage filter. I’m excited to see how this performs over our summer trip!

Until next time,
