New DIY Build Underway

[kimkats]

So “they” is....me ?.

OH YES IT SURE IS!!!!

Okay so here is where I am coming from for more support under the steps.............On several steps like that in older pools someone will come in asking for help fixing the steps. They have a crack in them from......................not being supported all the way across........see how there is only that one "pole" under the middle of that other step? What can you use to put something all the way across so you will never come here to ask how to fit them. What about PVC poles? I see a square with legs on the bottom to keep it in place as you put sand or what ever you are going to put there.

You can only use 3/4 now under the stairs and you gotta carefully pack it in horizontally. I had an early long day i just got done from 630am start. Didnt see u post. Ideally you would have formed the whole step up with plywood and just poured it for best result. Just be careful when back filling. You got quite the overdig on short side what's ur plan for material on backfill? Also keep an eye on machine when reaching over check grade often. Regular operators always dig too deep. Probably gonna have to rake the teeth to loosen it up when ur close and just flat shovel the tweak into the bucket to swing out. Use gravel to build up if u end up needing to not dirt

Ahhhh....I see...and correct. So that last picture was just the one leg as a mock-up for fitting and alignment. Here is the final step all locked in. It has 3 legs on the upper step. And 2 on each of the remaining. The bottom step is completely in concrete. The second step has legs but only 3 inches are above concrete. The step is so solid this morning...just did the-twist on the top step and not a wiggle.

I was lucky to pull a beautiful volume of bank-run out of ground and more to come from the hopper.

SWEET!!! Looks good to me!!

Thanks for all your help and advice. I ended up closing in the walls with the collar...the wheels came a little off the bus with the concrete delivery.

After a pretty thin layer of clay, I was blessed with this really nice volume of bank run. All course & fine sands and gravel. More of this will come out of the hopper.

I planned on using this behind the steps AND for the backfill. Attaching pic of steps with all the legs in. It’s very solid. This fill will compact quickly and will fill the voids I think really well. I know you said 3/4 but feeling like this material is pretty good for the steps. Thoughts?

As for backfill, again I’ll use this bank run with a 5” top layer of RCA to be ready for pavers. The collar is a solid 8-9”.

Can I/would you backfill this pool at all or completely before liner/water?

stay safe out there.

 

[Tbwonder]

Ok good ?

 

[Tbwonder]

SWEET!!! Looks good to me!!

So I just posed this to JimmmytheGreek too....but it’s an open question I guess. What’s the feeling on backfill before liner/water? Is any backfilling ok? None?

 

[kimkats]

I am leaving that one for Jimmy. I really am not sure and he KNOWS so lets wait on his answer.

 

[jimmythegreek]

You can do liner and water now. I like to wait and do it in tandem or keep water to the bottom of returns. The water gets trashed backfilling with sand dust and even stones use lots of water amd small lifts like 2 to 3 inches. It's really hard to get bank run compacted well near the walls. Ive seen a plate compactor blow out walls if not careful. You gotta hit it with a big plate or a jumping Jack amd just get close to braces not against sheet metal

 

[Tbwonder]

Jimmy question on skimmer install: the order is faceplate-gasket-liner-steel-gasket-skimmer. Is that it? Do you add a gasket between liner and steel? Any silicone or sealant anywhere?
Regular cork gaskets that come with it...just seems so simple/minimal.

Also, any additional support beneath skimmer prior to backfilling? I have Hayward skimmers...was going to add a pipe to the second closed port as an additional leg. Any other thoughts on supporting skimmer?
Thanks

Second hole use a pipe capped as a support leg I use the back hole. That's all that's needed keep an eye so it doeant get cocked or out of level when backfilling the sheetmetal flexes. Depends on skimmer type some get gaskets sandwiched between liner and some get only 1. What model skimmer do you have

 

[Tbwonder]

This is Hayward SP10852OMDGR. Gasket schematic below. Just seems like there’d be a gasket between the liner and the steel wall.,..per their spec it’s just liner right to the steel wall. Was wondering in practice if this is what’s done or do you all add a gasket or silicone anywhere....or just dry fit to spec as it’s printed?

thanks again!

Yup that's how it goes seems odd dont it? I use a bead of silicone behind all of them always clear. Domt put trimplate on right away check screws after some warmer weather. Never a drill always hand turn all pool fittings snug they strip

Ok. Yes seems crazy. You essentially have that edge of the steel wall sandwiched in there but it’s exposed. I mean it’s ZAM coated and I’ve also sprayed some rustoleum on that edge but just odd.

I have silicone. Will put on all surfaces.

thanks for counsel.

Here is my hopper dig. That’s the guy in the machine and me alone hand shaving the walls. Yeah...today was a lot of work. Think it went pretty well.

 

[Tbwonder]

Progress

[jimmythegreek]

the skimmer throat should be through the wall and the liner gets sandwiched to that with gaskets. NO PART of the steel wall should be exposed to the water. theres a little ridge on the inner most part thats the contact point its all plastic contact make sure of that

Yes when I installed it, it goes differently than what it looks like in the diagram.

I siliconed the gasket to the skimmer face, then installed skimmer. The Gasket on the skimmer just contacts that steel edge a hair but the ridge on the plastic presses it through.

Do you normally just install the skimmer through and THEN put the first gasket on? Is what I should have done here?

Thanks again.
Also the hopper dig produced more sand, less gravely bank-run. Sand will be better than bank run for the backfill right?

Can you slow down sir? You are making me look bad on my solo pool project Looking good there, gotta say I hated shaping the hopper.

Yeah that day was brutal. My usual cast of helper characters is thin due to all this current lock-down state we’re in. I too am a solo operation here. Have someone doing a vermiculite floor and installing liner on Sunday...so I’m pressing hard to get squared away here for that.
