How can I get a inflatable swimming pool filled?

wow well i can't help you this far away but our swimming pool company delivers pool water in our full-size semi tanker...if you have a local fire department we always recommend them if you can't have a pool company bring it in. Be careful if the water they deliver is on a well. If so you would need to use a sequestering agent to help remove these minerals in your water to help make the water clear and not stain your pool and or your clothes with all the rust in well water. Even if it's not on a well its still great to use a sequestering agent to remove any type of minerals...all water has minerals just some are worse than others. We are a big fan of GLB products that are made here in the United States.
