We are looking for a knowledgeable person to size/check over our swimming pool design. We are having one built, but are hiring out the different aspects (not going through the local swimming pool companies to save 50k) but are not 100% sure we have all the plumbing aspects tip-top.  Is there a person we can email our plan to that could look it over and let us know if it's OK to go, or if we need to change anything?
