Debris Accumulating in Stairs

[cschnurr]

My inground pool has built in stairs. I have had an ongoing problem with debris collecting in the stair area. There is only minor improvement when I adjust the position of the eyeballs on the jets.
I do not have any jets in the stair, and there is a jet about 2 ft 'upstream' of the stair opening.

Last week I installed a 90 degree elbow (from the plumbing section of the store) and attached an eyeball to return jet. So far It works fantastic, the water flow bounces upwards off the steps, creates a flow off the wall that keeps the debris out of the stair cutout.


If someone decided to use the elbow as a step, could it crack the threads in the pool wall? Would that be a cut the concrete, and digout to replace the jet?
Is it worth the risk?

I see there various some 90deg elbows available specifically for pool jets. The tradeoff would be keeping a low profile to minimize potential damage to the pool while maintaining a good flow rate.

Here are two Hayward options:
Hayward Slotted Directional Eyeball Pool Wall Fitting Return Jet SP1419A

Others include
https://www.spatex.com.au/waterway-1-flexible-90-degree-return-eyeball-1.5-m
Infusion Threaded Inlet V-Fitting

Would you recommend any of these?
This could also be ideal in my neighbours' 1970's inground pool that could use an elbow to achieve a circular flow around the pool.

Nice setup!
It is possible to significant damage. Can't assess your risk. Do you have people that cannot follow instruction to not use it as a step?

The last two you listed are better options than the first two.

I would agree and say potentially yes, it is possible. That would be a bad thing. I currently have one return jet with a cracked threaded inset (due to soil settling) and I know eventually I'll have to cut & dig to operate on that rascal. Not looking forward to it. But is it likely to happen? I guess it depends on the activity you get in the pool. I agree with PS that the later two options seem a bit less risky.

Thanks for your input.

The risk of using it as a step is low. Really only if I have young children over and they lower themselves in or out of the pool especially when people might be sitting on the stairs. But the impact is fairly high so I wanted to see if I could minimize it. My concerns with the Options 1 and 2 are that they are such a low profile, that they would have such a pressure flow ((high velocity, low flow). I think you agree.

I had an incorrect link, the other option I was considering is
90Degree Eyeball
This looks like it would give me the flow, direction, and the fact its a ball would like move or crack the ball if stepped on.
