Middle of Build. Any issues? Plumbing inside of concrete

But it doesn’t appear to be hooked into the power and I’m not sure how they would have actually tested it. sssiiiiggghhh.

For the pressure test pipes are not connected to equipment. They are caped off at one end and all looped together by the equipment pad with a spigot and pressure gauge. All the pipes are pressurized together at 25-45 PSI and it should hold for at least 48 hours.

I see that. But it doesn’t appear to be hooked into the power and I’m not sure how they would have actually tested it. sssiiiiggghhh. Thought I learned a lot before starting this process but apparently not enough. Didn’t even think to inquire about this.

My entire system was pressurized for like a week. Have you ever seen that gauge show pressure? There is no power for it.

This is the only gauge I see. First time I’ve really looked closely at it and it’s on 0

That gauge is on top of your filter and can't be used for a pressure test.

Step back and show up what your equipment pads looks like .

I think gunite is supposed to happen Friday or Monday and I don’t have any idea if they plan to continuously monitor it throughout the process. It hasn’t been mentioned.

The company should have the pipe pressure tested during the application of gunite - this protects them as they do not want a leak during the process or even afterwards. I remember in another thread on this forum, the gunite force broke the PVC and they had to stop and do a repair. While this is rare, it is the reason they should maintain pressure on the pipe when they apply gunite since the pipe is inside the rebar and gunite structure.
They may have done a test initially then removed the test fixture.
Can you post a picture of the equipment pad showing the pipes coming up from the ground?

It’s not that difficult to fix it now, especially compared to trying to fix it later if there is a problem.

I cannot say that it will definitely be a problem or that it will not be a problem.

Texas seems to have zero requirements for someone to be a pool builder, which seems to be incredibly irresponsible on their part.

They should have some sort of qualification procedure.

You have to decide to trust the builder and just hope for the best or maybe consult an engineer to get a professional opinion.

Can you show some better closeup pictures of the plumbing and can you measure how thick the concrete will be around the pipes?

Part of the problem is "Shadowing", which is where the backsides of the pipes are not covered in concrete because the gunite or shotcrete is shot into place rather than poured and this makes it difficult to get sufficient placement behind large rebars or pipes.

You might have a very long section with only 3" of concrete thickness, which is likely to crack if there is any stress at all.

Gunite or shotcrete is shot into place with high velocity to compact it in place and getting sufficient concrete behind structures is difficult especially getting it placed with velocity and compaction.
