Central Vac Installers! Please STOP using This Fitting

The "three way tee" or "double wye" or "baby butt" fitting invites blockages and buildup in your central vacuum piping. Here are a few "best practices" to join vacuum piping connections.

Exactly what I was trying to understand. Why there were no "evil" tees on sale at my hardware stores. Thank you.

Might I ask: you seem to really like the 45° fittings, whats wrong with sweep-tees?

[@Centvac]

Great question! The sweep tees are acceptable but I prefer the 45 wyes because they are a more versatile fitting and also provide a more gentle entry angle for the branch line. On commercial jobs and retractable installs, I would recommend using 45 wyes exclusively. For residential traditional system installs we often use the sweep tees with no problems.

@Centvac Good info! Thank you very much! I installed a traditional system back in October in my house but I'm thinking a few years down the line of switching to Hide-A-Hose and an MD Silentmaster, so this is very good knowledge to have handy.

definitely The most clogging fitting !
