How it goes
Find the inlet placements by measuring from the
outside perimeter inward. The hose lengths are 25,30 and 35 feet. I aim to put
the inlets in the halls and not inside rooms. You will get more coverage and
also the inlets will not limit the placement of furniture inside rooms. Also
doors will open into rooms and thereby the inlets in the halls can't be blocked.
Now that we have an idea about where we want the inlet we need to drill through
to pass the pipe. Before drilling the 2 1/2 inch holes I always put a small 1/4
inch hole and a hard wire probe through so I can go and look to see really where
the big hole will go through. This step is most important because you don't want
to drill through floor joist or wires, pipes or radiant floor heating system
tubes, ect. With SCV you will not have the structure compromised by improper
drilling or notching. Now that the holes are drilled through the inlet ruff
bracket will be attached to the wall stud. The inlet bracket for the inlets are
different from the other things like electrical switches in that they are
attached to the front facing side of the stud. This can make getting the inlet
straight hard because of the grain of the wood. The inlet bracket comes with pre
drilled screw holes but often these holes are not in a good position in relation
to the grain making it impossible to get it strait. The remedy is to drill other
holes in the bracket that will line up with the gain and then it can be set
strait with a level. I had a guy from another central vac company that said he
just put the inlet bracket on loosely so that when the inlet finish door is put
it can be straitened later? I don't think so. The inlet height off the floor
needs to be considered as well. Unless I'm told otherwise I will simply put up
the brackets in line with the other things on the wall, like the electrical
outlet plugs. The pipe run will run from the bracket away towards the tank
location now that the inlet ruff brackets are set. I always put a pipe strap
near the inlet bracket to isolate it from any stress from the pipe again to keep
it strait. As the pipe run extends away I minimize the angle of turn at the
elbow as best I can. I use the 30 degree turns and not the 45's that I always
see used by others. The 30's give a better flow with less restriction. I always
use the blue PVC glue at my connections to that when I go back to inspect my
work I can see that yes it is glued and there's no question about it. I always
dry fit my work together so that I know it will fit together easily and not be
forced together. Improper or not glued connections are the most common reason
for a problem with the install. Deburing of the cut end of pipe are another
super important thing to do to prevent clogs. Don't assume that these most basic
steps will be done, you need to make shur of it. I you use us for your install
you will know that It will be done right. You don't want not right. Along
the pipe run there will be connections where two pipes join together. I would
not allow for a "gravity drop" where dirt from one pipe can fall into another at
a connection. This gravity drop error is another reason for clogging that I have
seen. Again, if the install is done right then you won't have a problem. As the
pipe continues along there might be times when the pipes must pass through a
Sheet rocked barrier. At this point I convert the pipe to metal to satisfy fire
code. This happens most often in commercial installs or when the pipe enters the
garage area where the CV tank usually goes. Another kind of inlet is the
vacpan. The best place to put these are under cabinets and not under anything
big and heavy like an oven. These are designed to fit into a standard 4 inch toe
kick space. I ruff it up to the general location and positioned to point towards
the face for final hook-up later. I also will use a
couple of 30's to get the right height to meet with finished floor level.
I could keep going but I
think you get the idea. There really can be a big difference in quality of
workmanship. With SCV you will get the best there
is.
