These guys are passionate about making good spas and it shows, they have been building hot tubs for a long time and they have tons of experienced staff. I toured PDC’s factory in Pennsylvania and was thrilled with everything I saw, they were really open and happy to show off their production line. These guys are making a solid reliable hot tub and their quality control practices ensure every tub comes out to the same high standards.
PDC is building their shells right, vinyl ester resin core, layers of hand-rolled fiberglass and matting for extra reinforcement. They are solid and long lasting.
Everything is glued and clamped which goes a long way to preventing leaks and their manufacturing process here is very well executed, they prefabricate the manifolds to exact standards so there is no extra pressure on any of the attachment points and no extra vibration.
They use OEM parts and Balboa heating and control systems which are the best out there by far, they hold key patents that put them well above any other competitors. Getting quality OEM parts you can easily source is important to long term satisfaction.
They use a mix of Mylar and high density foam, this was my biggest issue with their tubs, I’m a big supporter of using a full foam system (not the cheaper ones that harden). That said it makes less of a difference if you are in warmer climates and there are plenty of other brands out there doing the same thing or doing it worse.
All in, these guys are definitely in my top tier of manufacturers.
