Central Vacuum clogged

Our central vacuum doesn't seem to have much suction. We'll blame it on our constantly shedding, always loyal dog. We've changed the bag but believe hair is stuck somewhere in the middle. Any suggestions to clearing it out?

Always check the hose and bits that you connect to the inlet first. Keep it simple.

Attach a few long strips of the hook side of Velcro, like a stringy Pom Pom to the end of an electrical fish tape and shove it through. You want to avoid making it too heavy to avoid pulling on flexible sections or getting it stuck.

You can also try tying the Velcro glob to a heavy duty line and suck that into the system and pull back out.

I just happened to see your post in the "Recent discussions" box. When I was in business we sold central vacuum systems for homes. The pipe in the walls was larger than the hose, so anything that was gonna clog the system would normally clog the hose. Not sure if that's true with RV systems. You can use a garden hose and run the male end through the hose to clean it out. I won't be following this thread, but hope this helps!

Did you make sure that you took the extra bags out of the actual vacuum. For some reason they store the extra bags in the vacuum housing. I know you said you changed bags but you may have just went and bought some not knowing they give you extra ones. Our suction was very weak at first, but we took the vacuum apart and found the extra bags stored under the attached bag. Took them out and it has worked great since.

There is a floor sweep opening under the hose connection. Make sure it's fully closed.

I haven't looked in awhile, but I believe there is a white filter pad at the back of the filter box. After you remove the bag, look in there for a second bag as noted above and make sure there isn't a square filter pad in there.

Check this website, it has a picture of the secondary filter pad in the unit at the back. RV Central Vac - H-P Central Vacuum Accessories

Thinking you have surely checked to be sure all the connections are good

Not on the outside but inside, behind the wall - normally they are just taped - often the tape will come loose and cause you to lose suction.

https://www.amazon.com/Wesy-Multi-Pu...ct%2Fhvac+tape - if not this at least this type/quality.

IMHO if you look you will likely find lose connections and/or holes in the line.

I've repaired mine and was surprised at the number or repairs needed -especially at the main connection on the floor.

This tape is now in my tool box - and you will be amazed at the uses you will find for it.

Hope this helps,
