🚨 THE MORE WE OPEN UP THIS SHOWER, THE MORE WE FIND… 🚨
Yesterday we showed you what was hiding underneath the tile and waterproofing.
Today, we opened the walls.
And now we’re talking plumbing. 😳🔧
Take a close look at these pictures. You’re looking at multiple push-to-connect/SharkBite-style fittings incorporated into the plumbing behind this shower — and several connections appear to have glue, adhesive or sealant smeared around them.
And here’s the kicker:
💧 WE HAVE ALREADY DETECTED A LEAK.
So let’s talk about SharkBite fittings for a minute, because there’s a misconception worth clearing up.
WHAT ARE SHARKBITE FITTINGS ACTUALLY MADE FOR?
SharkBite fittings were designed to make plumbing connections quickly and without traditional soldering, crimping or gluing.
They’re especially convenient for repairs, renovations, tight spaces and situations where connecting different approved types of pipe would otherwise be difficult.
You cut and properly prepare the pipe, insert it to the required depth, and the fitting’s internal components mechanically grip the pipe while an O-ring creates the watertight seal.
That’s the whole point.
YOU DON’T GLUE A SHARKBITE CONNECTION.
Putting glue, silicone or some other sealant around the outside of a leaking or questionable push-to-connect fitting isn’t what makes that fitting watertight.
If the pipe isn’t cut square…
If it isn’t properly deburred and prepared…
If it isn’t inserted to the proper depth…
If the O-ring gets damaged…
Or if the fitting isn’t installed according to the manufacturer’s requirements…
Smearing something around the outside isn’t the answer.
Now, here’s another important clarification:
SharkBite fittings are not automatically “temporary-only” fittings. Certain push-to-connect fittings are approved by their manufacturer and applicable plumbing codes for permanent installations, including some concealed applications when installed correctly.
But here’s where workmanship and professional judgment come into play.
When I’m building a shower that’s potentially going to be covered with waterproofing, backer, mortar and thousands of dollars worth of tile…
I DON’T WANT A WALL FULL OF UNNECESSARY CONNECTIONS AND POTENTIAL FAILURE POINTS.
Every fitting is another connection.
Every connection is another place something could eventually fail.
And if that connection is buried behind a finished tile shower, getting back to it isn’t exactly as simple as opening the cabinet under the sink.
That’s why the plumbing BEHIND a beautiful shower matters just as much as the tile you eventually see.
And in this particular shower, this isn’t hypothetical anymore.
We already found a leak. 💧
First we discovered improper waterproofing.
Then a saturated mud bed.
Then standing water above the liner.
Then no proper pre-slope.
Then an improperly installed pan liner.
Then wet wood at the curb.
And now we’re opening the walls and finding questionable plumbing connections with an active leak already detected.
This is exactly why I keep saying:
A SHOWER IS A SYSTEM — NOT JUST TILE.
The prettiest tile installation in the world means absolutely nothing if the waterproofing, drainage and plumbing behind it aren’t done correctly.
Most homeowners will never see this part of their shower.
But this is the part that determines whether that beautiful shower lasts.
We’re still in demo mode…
And apparently this shower still has more secrets to tell us. 🤦♂️😂
Stay tuned. We’re tearing out the shortcuts and rebuilding this one the way it should have been done the first time. 🔨🚿
