Removing remaining water from hose bib lines
Author: gbonawitz (PA) I have some cpvc pipes leading to a hose bib that most years still freeze and cracks even though I drain it. Does anyone know if they make cpvc bleeder valves that I can use to let some air in to remove any vacuum holding water in the pipe? I've looked but can't find any. Thanks

Author: Paul48 (CT) You need a valve that incorporates a drain port. There's a couple different varieties. Make sure the drain port is on the downstream side when installing. If the piping is exposed, you might consider sharkbite fittings. Merry Christmas!!!!

Author: packy (MA) you might be able to use a shop vac stuck over the hose end of the sillcock. it may get enough water out? as suggested, a shut off with a drain in it will help if the pipes don't sag near the outside.

Author: hj (AZ) It is not just "vacuum" causing your problem. Hose bibbs are not designed to drain ALL the water out of the pipe, even if the vacuum is broken.

Author: North Carolina Plumber (NC) Correct, a tee with with a Schrader valve downstream of the water valve will allow you to inject a shot of air to remove any water standing in the pipe. $20 worth of parts including a bicycle tire pump would give you peace of mind as far as having any burst pipes.

Author: hj (AZ) Instead of a shraeder valve on the tee, install a drain valve. It will be more positive draining than depending on air blowing all the water out.
