My PB made the repairs and retested at 10 PSI (water fill).

Pool concrete deck approx 1200 sq ft. (4" thick slab, 3/8" rebar on 18" centers). Surface is coated with the drag texture "spray deck" and sealer. ITEM #1 Within one week hairline surface cracks have appeared; 5 cracks that run the approx 3' to 7' long. I know slab surface cracks are virutally...

Anyone know what the effects are to plants (grass & young trees/shrubs) with regard to water running off of new concrete? The water appears amber/green and is very "slimy" to the touch which means the pH is on the base side (probably 2 - 3 if I guessed). It is highly irritating to the skin...

Part I: What is the acceptable PSI range for the pressure test on new construction pool plumbing? The manifold consists of sch40 2" and 2.5" pipes for pool, spa, water fall. Information seems to vary but typical operation will have 10-15 psi and could spike as high as 20-25 psi. I've read...
