Engineer who did the plans did confirm I can go 6” instead of 3” if using #4.

Forgot to answer your question. It’s not a case of a builder telling be to go another way. I’m doing an OB and I’m now preparing a package to send out for quotes, and I suspect many will come back with cheaper options of Different spacing. I‘ve sent the engineering company a request if they...

I was thinking about getting a test run also. In the map of the state, yes, Houston is in the highly expansive area. im also wondering if I’m reading the tables above correctly. And if the spacing of 3” is only in the area where depths reach beyond 6’. If that’s the case, it’s really only...

Thanks. When I looked up expansive soil maps for Texas, everything around Dallas and Houston show Highly expansive soil. I know it’s a lot of clay. the drawings state PCF of 60. In reading some pool engineering articles, seems like 60 is not really, really high, but above avg. builders...

I should also note that the pool builders I received quotes from all used 8” spacing, and suggested it was generally the standard unless a special case.

In reviewing my plans, the engineering seems to be calling for fairly tight vertical spacing. The plan is for (what I believe) a pretty standard geometric pool, 3.5’ to 6.5’ water depth, with a raised wall on one side. Build is in Texas, so land doesn’t get much more flat. Looking at the...

I’m still finalizing the plans, and getting quotes. I can already say that it’s true, you won’t save as much as you think, because you start spending it on upgrades or in areas to get a better build. From what the pool builders were quoting me, I believe I could probably save +25% if I did...

Thanks. Yes, I was planning one or the other, but noted the 2” line of jets offered the variety of different flow rates. One more random question when preparing the hardware list. For the main drains in the Spa, if I’m targeting 100-120 GPM, should I be looking at the HF drains like these...

@mas985 , in the links above, am I correct the Gunite body would all be the same, and the Jet internals dictate the flow rates?

That image was the 2" model, but they have the same diagram, with more detail for the 2.5". The way I'm reading it, the Flow is dictated by the jet internals/insider, and not the Jet Bodies. So I'd order X# of Jet Bodies as they're all the same, and then select the Internals I want, based on...

so this occurs in the Gunite body assembly in this pic? Where the air line has the slot at the bottom. what makes it confusing is the internal jet says 10 GPM, but there’s nothing referenced for the Gunite body. For example, Looking at the CMP site, the Gunite body lists pipe sizes, and Jets...

And the jet orifice is in the jet body itself, Correct? Everything else in that diagram can be selected irregardless of the Jet body. just seems odd that so many jets online don’t seem to list GPM, or the Orifice size. Just the pipe size.

When building the Jet hardware list, what components dictate the flow requirements? Is it the jet itself, or do tee’s orifices need to be selected? I was looking at the Poly Jet hardware and the jets have GPM listings, but then it also has a list for orifice choices for the non-adjustable...
