recently purchased a new cerveny 686prx horn.For me a very nice fit being a 60 yr old amateur.Has only one "spit valve" that seems to fill up fast.However, even after emptying still notice water in horn.Requires horn to be inverted and slides removed to empty due to design of horn.Any one with this horn have same problems? Just a nuisance or maybe lazy? My question:is this normal with all horns or just this design. may be a silly question and realize bigger problems in world but can not remove when playing in concert ect. thanks jds

This is a rotary horn with horizontal main slide? In my old Weltklang water is condensing in the loops after the tuning slide, this is moisture condensing out of the breath on the cold metal tube walls. This can not be drained through the water key. I remove the main slide an turn the horn horizontal and tilt so that it comes all out.
wish you succes!

I think the style is that of the Mira 186; if so, do a double spin counter-clockwise with the 4th valve slide out. Watch your shoes, though!

You can spin in in direction to bell or to tuning slide ( which is out then). I think it is in the main bugle. If it is in the 4th valve tubing, then of course another procedure takes place...

When I play a 186 I usually pull the main slide and tilt it to my right. The only other one I seem to have to pull to empty is occasionally the 4th and that depends on the 4th valve wrap of the horn (186 needed it, 187 does not).

Have the same issue with my 686 (5PRX) and with my old 681 (same wrap). With the 681, 2 or 3 top-to-bottom turns would drain it out the bell (away from my shoes), but the 686 is a bit less wieldy. Taking the tip from tubajazzo's post above , I am trying the horizontal tilt to bring the condensate back from the 2nd loop into the the 1st, which has the water key and tuning slide. Then I can use the water key to drain it.
Seems to be working so far. However, it's a one day trial, and there may be condensate in loops further around. I really try to avoid pulling slides all the way out when I'm in a situation in which I can't be careful.
