We haven’t gathered owner reviews of the El Grande X-Series EC-1166EX yet. The company's complaint record is below.
How it’s built. The 8 build checks, in plain words.
The same eight checks we run on every brand, answered from Cal Spas’ own documents. Tap one for what it means and the evidence.
Self-supporting shellDoes the shell hold itself up?Not published
Clamped plumbingAre the hoses glued and clamped?Partly
Barbed and glued joints confirmed. Clamps are the unknown part.
Jets connect with barbed fittings and flexible hose, and the rigid runs are solvent-glued PVC. The factory store sells no hose clamps, which settles little either way since clamps are a bulk shop item. Nothing published says how the barb joints are secured.
Applies to: All models (from the factory parts catalog, which doesn't split parts by series)
Manifold-fed jetsDoes each jet get its own line?Not published
Standard partsCan any repair tech buy the parts?Partly
Balboa or Gecko controls and Waterway jets, but fitting your own voids coverage.
Control packs come from Balboa or Gecko depending on the series, and the wet end is Waterway, listed under Waterway's own part numbers. The factory parts store sells to the public, and outside distributors stock the same components. The warranty is void if aftermarket parts that aren't genuine Cal Spas parts cause a failure, so buy from Cal Spas while coverage lasts.
Applies to: All models
Compression-fitted jetsAre the jet bodies held by a nut, not glue?Yes
Jet bodies bolt in with a nut and gasket, per the factory parts store.
Cal Spas' factory parts store sells body nuts and gaskets for every Waterway jet family it uses, at about $4 to $5. A cracked body can be unscrewed instead of cut out. One push-in grommet body is also listed, so a few tubs may differ.
Applies to: All series
Adjustable jetsCan you turn each jet up or down?Yes
Almost every jet turns to raise or lower its pressure.
Turn a jet face clockwise for more pressure and counter-clockwise for less, with the neck jets working in reverse. Air knobs and diverter valves control whole groups, and the ATS seat adds its own pump and panel. Cal Spas does not say which jets are fixed.
Applies to: All models; the manual says "almost all" jets adjust, so expect a few fixed ones
Service networkCan someone near you fix it?Partly
Dealers handle service, but the warranty terms are unusually strict.
Warranty work runs through your dealer, who may still bill a travel fee and a diagnostic fee. Coverage ends if anyone but a designated rep works on the tub, if non-genuine parts go in, or if you sell or move the spa. Cal Spas publishes no dealer count.
Applies to: All models in the US and Canada; other countries have their own published process
American made?Built in Pomona, California.Yes
Pomona, California: Current 40-acre headquarters at 1462 E. 9th Street. Pomona, California: A UK trade report describes a 1-million sq ft manufacturing facility.
Applies to: All models
