Pool Fill Plumbing

This pvc connector from the hose bib to the fill line has broken - I'm having trouble sourcing anything similar. Does anyone have any suggestions on where to find something similar or an alternate way to connect this? Thanks.

Cut the broken fitting off as shown. (If I'm seeing it right)

Bring them, and the in-between piece to a plumbing supply store (note, not HD. You want where the plumbers go).

Show them the parts and the pic and they'll disappear in the back for a minute and come out with everything you need.

HD/Lowes is hit or miss with specialty parts like flex pvc, and the employees are also hit/miss when looking through what they do have.

That looks like 1" Flex PVC...can you measure the diameter and post back? Size will change recommendations.

3/4" Flex PVS Outside Diameter: 1.050"
1" Flex Outside Diameter: PVC 1.310"

Did it break because of freezing weather or because someone tripped over it? I’d cut out all the flex PVC and run standard rigid pipe with a way to blow it out during/before freezing weather.

And to plumb it to code. You need a backflow preventer on the auto-fill line.
Stay away from that flex hose as well.

That looks like a I-gotta-get-outta-here-lets-see-what-I-got-on-my-truck plumbing job if I've ever seen one! None of that should have been left like that.

As others have suggested, it should have all been hard-piped, there should be a proper valve, and it should have all been insulated.

- Are you planning to fix this yourself?

- Why is it not gushing water? Is there a shut-off valve somewhere else? If so, can you post pics of that valve?

For all we know, you might already have a backflow preventer installed...
 
Thanks all - there is nothing fancy about this. Just hooks up to the hose bib, I turn it on manually, pipe on right terminates above a skimmer for the purpose of filling the pool - and it works fine. Pipe on left goes to outdoor kitchen and has been broken a long time.

Nothing automated, no floats involved, no need to backflow as it's literally the same as running a hose to the pool, just underground.

I took it off as I usually do to cover the hose bib for cold weather, needed to top off the pool and it was still cold but snapped.

Don't really want to hard pipe it as I need the flexibility to disconnect it in the winter.

Just looking for best practices - yes I'll fix myself, happy to dig down to the 90 degree bend underground if needed. I've seen a friends connected with a washing machine hose which does offer more flexibility but seems janky to me.

best idea so far...

OK, now I get it. You're right, no special vacuum breaker valve needed. You actually already have a backflow preventer (BFP). When water falls through air before it hits your pool, that's a BFP, more commonly known as an air gap.

This is what I'd do:

You'll find adapters at your big box store to convert either or both of those two PVC pipes to hose thread, then just attach them to your hose bib 1-to-4 splitter with 3' hoses. Remove the hoses for winter. Blow out the pipes, then cap them to keep them from filling with rain water.

You'll need some PVC primer and glue to attach the converters to the pipes, but everything else just screws on. About $35 in parts and materials will get you squared away.

I wouldn't use flex again, it'll just fail again. It's not supposed to be exposed to the elements like that. You can throw your little hoses in the garage in the winter for safe keeping. And they're easy and cheap to replace should they ever fail.

I put one of these on every one of my hose bibs, and haven't flooded my garden since (which I used to do regularly). So far, they seem to work great. One of these on your pool filler valve would keep you from over filling the pool.

Oops, thought of one more thing. If you're planning on restoring the "non-pool-fill" pipe, I think you said that one feeds an outdoor kitchen, the hose you use for that one will need to be "food grade," or have some such designation/quality.

Something like this:

In that case, that 1-to-4 splitter should be food-grade, too (drinking water safe).
