What do you do if your vac pipes are leaking inside the walls and how do you know if they aren't? Also I occasionaly vacuume something that I need to recover from the bag or canister, how do you do that with central vac if it is somehwre in the pipes?
P.S. I personally hate vacuuming and let my gang of robots do the whole thing. They clean the house well and entertain the cat.
The pipe install is plumbing grade PVC. Given the low wear and tear occasionally running a light vacuum will put on that install, vs. constant pressurized water flow, I'm pretty sure it's up to many years of service. As far as idiot proofing the act of vacuuming, years of having hundreds of employees have taught me as much as I think I've idiot proofed something, I can always hire a bigger idiot. If it gets stuck in the pipes call a plumber to snake it; if it doesn't it's in the canister just like any vacuum.
