Do not order the NSPI 3 Standard for Permanently....the $60 version or so. It is usless to the owner
builder. Try these docs Mike Holt Enterprises PDF distillation of the NEC 680 for pool and spas. I highly
recommend this PDF. Thanks to Mike Holt Enterprises! The PDF is here also on my website.
Also, custombuiltspas.com. Although they are rather light in exactly what parts you need. Their books give
you a good general idea as to how to build the shell. The weakness is in the specifics of pump sizing,
where to get the parts(they sell them!), etc. But for the price I found it worth it.
Much better that the official NSPI brochure for $60. There is another book they sell for $300 I imagine that
may have what you need in there.
Also I have not gotten my spa approved by the County and it looks like I may not do this due to the fact they
just aren't set up to deal with someone that is doing it themselves.
Aqua-man.com is where I purchased my jet specific parts. Ebay the pump, electrical stuff, etc.
2006 - June
Constructed in a few hours...This is my spa.
Hopefully. I've had it completely assembled now for a few weeks. But I'm having trouble with
zoning, declaring which side of my house is the front. Which determines the spa placement.
So I'm likely to have to wait until this is all over before putting it in. I'm going to have trouble
I've developed a plumbing system and jet arrangement that'd I'de like to test soon. Also the
pouring of the concrete and finish will be perhaps a bit tricky.
I still need to order the skimmers and all parts mechanical. Which I'll make a list of including
pumps wiring etc.
After growing tired of seeing an aging foam cube sit in my front yard turning yellow, I am
pursuing the spa again.
The County insists that my spa be engineered. Certified by an engineer. I asked If I would
find a spa or pool engineer in the phone book and they said they could not recommend
anyone. Well, there aren't any listed and, I asked my structural engineer if he'd ever heard
of any such person and he said he hadn't. So I have ordered the NSPI 3 Standard for
Permanently Installed Residential Spas 1999. To which our current code says the spa must
be built to. I will include all of this into my design, submit, and appeal should my permit be
denied. I suspect that this is a boiler plate response by our permitting department to weed
out DIY like me.
I have learned in the process a number of important safety measures that should be
included in a spa and I'm glad they actually turned me down initially. We'll see what happens
when I've put in everything that should be in there.
I have also changed the design of the spa not to include the ICF bench seats. The problem with getting
concrete in there was too difficult to figure out. I'm using a box in the center know with a sub structure. I will
post pictures soon.
Note the less than pristine condition of spa cube and I'm not so proud of the pad. My workmanship has
definitely suffered but I need to finish this job in the most expedient fashion and throw to the wind any flaws
that are not a critical failure. The day I poured the concrete the bucket I attached to the skidsteer fell off while
carrying the loads and the pump jack on the concrete buggy I rented did not work which meant I had to
shovel a considerable amount out of the contained by hand.
The things that happen when you do-it yourself!
