A question to those used Spa-flex.should the 1.5" spa flex it tight like a PVC on any fitting or should it be loose and use some kind of transition fittings.Because seems like mine fit loosely in the fitting and I bought this product
G941HT… SPA FLEX from
www.greenlinehose.com/
and the specs says
1.5" spa-flex with ID 1.65 AND od 1.90
