Pet Fountain Reservoir Adapter - Capacity Doubler
by rullmann, published
5-05-2013 - Revised slightly for better fit.
This will allow you to use 2 2 liter bottles as the reservoir for a drinkwell platinum pet fountain. This doubles the capacity from the stock reservoir.
2 Liter Bottles were previously Mtn Dew bottles in case there are differences enough between companies bottles. I kept the bottle caps and drilled holes in them to make it easier to cover the opening with my finger when installing full bottles, but caps aren't necessary for function.
