Hi, Thanks for your message again. Acctully, we have lots inventory in our warehouse in CA, and my family have our own factories both in Taiwan and China. So, please don't worry about the capacity. Also, if there are a lot of sedimentation in your area, we may re-design the pre-filter, post-filter and system to meet your need. We could offer the exclusivity for you, if we could make more business smoothly in the future. There are something we need to know to improve our business. 1.) Did you ever get any our RO system to test? 2.) Is the tap water pressure in your area enough to use the RO system directly without boost pump? (The RO system could start to generate the pure water at 35PSI, and the best situation is 65PSI.) 3.) Would you like to import the RO systems excepting RO membranes from our factories in China or Taiwan directly? (That will save your more cost than shipping from continantal.) 4.) Would you please let me know more about your company, like name, address, website....? ReQ
