It's not worth it, bong water is just disgusting

If you are wanting reclaim from a water pipe, use adapters or a dry ash-catcher to collect it... then reclaim from that. The more dry glass you vapor goes through before water, the more reclaim you will get. A simple GonG adapter with a slight angle is enough to keep some goodies out of your water pipe. Two 90 degree (or more) turns on dry glass would do a pretty good job of catching what you want while maintaining potency of your vapor.
Also, having those larger vapor particles get stuck on dry glass before the water will provide a smoother hit... like a long whip is smoother than a strait stem. Try different things to see what works for you.
There is also the option of using cotton or hemp fiber to filter the vapor for reclaim and/or reducing harshness -
Vaping with cotton
Just keep the reclaim out of the water and the water out of the reclaim.
