Glad parts still available
Glad to get a repair kit for a vacuum breaker valve that is no longer in production. Got the valve about thirty years ago and finally it needed new parts.

Glad I found their website.
Exactly the parts I needed for the repair. I had looked locally and could not get them.

BEST ANSWER: Hi, this repair kit is for the PVB by Conbraco and is not compatible with a Febco PVB. If you need a repair kit for the Febco PVB 1/2", please see the link below.


in this picture of the item #40-500-02 it looks like there is one more item but the picture is not clear. when I hover over the picture the letters SW come up and it looks like there is a white part also. I want to make sure this part is coming with this repair kit because that is the main part I need. Please verify tht I will receive this part. there is a picture of 5 items clearly showin and 1 item that is a vague picture. Please let me know thanks? Sam

BEST ANSWER: Yes the white float comes with it you just have to install the rubber gasket on it
Will this fit a 15 to 20 year old Canbracco Model no 405050?
