Skimmer replacement "circular weir" questions.

I have a pretty good idea on how to proceed.

But, any tips from anyone (pool owner or builder) would be appreciated.

please let us know how yr new round skimmer works. have just had one fitted and thought that the plumber had lost the wier and had to call pentair direct to convince myself that he was right and i wasn`t being worked over.

I got a late start today.

I measured from the ring seat (lid collar) to the bottom of the threaded fittings I was using. The threaded 2" fittings were threaded in and sealed with plumbers pipe thread sealant. Since my piping is 1½", I glued 1½" to 2" bushing into the threaded fittings.

I ordered the skimmer with 2" threaded fittings, as there were way more choices of model #s than I had with 1½" S20 skimmers. I just used a 1½" to 2" bushing, to make it fit.


Next I laid a piece of wood accross the deck and measured down the height of the skimmer + fittings. I compensated for a 3 cm (subtracted from the total lenght of skimmer & fittings) for the PVC drain pipe slip fit.


Measured multiple times, checked my calculations, marked the pipe, wrapped some tape around the pipe as a guide, and then cut the PVC drain pipe as level as I could.


I cleaned up the face of the pool wall, where the skimmer was to mate with. Used a chisel to make sure everything was flush as possible.


Test fitted the skimmer. Made sure the ring seat (lid collar) was below or level with the deck. The ring seat is adjustable, so I made sure it was just below deck level, as I could alway raise it to the height of the deck, when it's poured.

With the test fitting going as planned. I didn't have to make any adjustments.

I put a couple beads of silicon around where the skimmer box mated with the pool wall.


I primed and applied glue the drain PVC pipe. Tapped the skimmer down with a wooden block, to make sure I went down to the proper slip fit. Finish plumbing the skimmer portion to the skimmer intake pipe going to the pool pump. Used wooden blocks to hold the skimmer level & plumb.

Skimmer ran great, no leaks with just the silicon and wooden blocks holding it in place. Kept it this way for a couple of days to make sure there were no leaks. It's only wet in the pictures from me rinsing the area clean.



Another good thing I found out. I found out why I was having so much trouble priming the skimmer line. When I was cutting off the old skimmer, I found my floating pool thermometer inside it. lol



I'm currently filling/topping off the pool, so I can test it and check for leaks.

Tomorrow,

• I will backfill the hole and make a form around the skimmer. Add some rebar and tie it to the pool. Then encase the skimmer in cement.
• Then pour the concrete deck to finish it off.

Dirt backfill


Small plywood form around skimmer. Some rebar re-enforcement tied to existing rebar from old skimmer. I put two u-shaped pieces in. Lower rebar pictured. Second one was installed, after several inches on concrete was poured.


Concrete drying. Skimmer working perfectly and no leaks.


Video:
Circular weir in action. Clicking noise, is the Kreepy Krauly cleaning the pool. This is with the skimmer equalizer valve nearly fully open (underneath the basket). You can adjust the skimmer action by adjusting the equalizer valve.

Just need to backfill with more dirt and then pour the deck over the skimmer.
