I'm looking at adding some to my plumbing but am limited to horizontal pipe to place it will a high quality swing valve work horizontally or must it be placed vertically?

your title says check valve and in the content of your post it says swing valve. A swing valve will work vertically or horizontally, a check valve must be installed vertically to work correctly. Some manufacturers require or Suggest a minimum of six inches of straight pipe before and after a check valve.

Check valves are notorious for sticking open or closed because of mineral buildup or crud that can get lodged inside. Save yourself the future headache and skip the check valves. I would be hesitant to even mess with a swing valve.

I thought there were different designs of check valves and a swing valve was a style of check valve. Either way you answered my question as I'm considering a swing valve. Thank you.

No need for either. Try installing a 45 degree piece of PVC upwards after your bulkhead. If you can get the plumbing Into your bulkhead above your water line then you should be able to stop the siphon quickly enough to avoid a flood.

I would like the check valve as a fail safe but as Ryan said they need to be cleaned and checked often as they do stick.

The ones that are clear cost a little more but are clear so you can sort of see the build up inside.
