I have a home with a unknown vacuum system installed without a unit or hose. How can I tell if it is compatible with Cana-Vac parts?
Most central vacuum systems today use the same face plate connections. Some older systems are a different story. Look on the tubing sometimes the make will be printed on it. Also take a face plate and look at it sometimes it will have the make printed on it. Ask a neighbor, most likely they will have the a system installed by the same company. The hose end contacts have to make electrical contact with the contacts in the face plate so they need be in the correct position. Also the hose needs to fit tight but not too tight. That is why replacing the face plates is the best option then it can be done. If Cana-Vac’s face plates fit your wall brackets then the face plates can be replaced. There is no way to be sure but to try one. Take the face plate out and measure the inside diameter of the face plate on the face side end and the inside end, it is tapered so they will not be the same diameter, (you will need a inside caliper), the measurement needs to be accurate. Also measure the depth
