Q: Is flood testing your shower pan really needed?

A: Yes it is. And here is why...

Why do we check our work? Because every now and then it just doesn't go so good. Like this last weekend. When the client noticed not on flood test hour 24 but flood test hour number 50 that there was a leak in my work.

How did it happen? Not sure...

Can it happen? More times than you would think...

Should you flood test? This is exactly why...

I'm glad Peter (Square Pusher) can juggle his schedule for me so I can preform this repair.

Make sure you flood these shower pans people and don't get comfortable. I have not had a failure in almost 5 years in my shower pans and I'm sure this will not be my last.

This repair will cost me some to fix and even more costly - mine and Peter's lost time. The client has been keep in the loop and nothing has been offered as an excuse other than Me or one of my boys made a mistake. I have tested this Nobel membrane and know it to be a water tight product.

My liner was a single sheet and the only holes I know of where the three from the compression bolts and they had Nobel 150 under them. I will look closer at my work and try and understand what we did wrong last week but I suspect that it will take longer to find the fault rather than just redoing it.

Mistakes keep us humble. Keep me cautious.

I carry $4,000,000 liability insurance and hope I never need it. I will keep up my multi day flood testing as this poorly built shower pan (my work) leaked after 2 days of flood testing. Not after 2 hours or even overnight - but around hour 50 of a 60 hour scheduled test...

What other safe measures do you pros take to ensure this does not happen? What insight can you offer up this wounded "Private" ???

We all make mistakes. ALL of us (as seen with Stacy's shower). So long as you're willing to get right in and correct them..... AND LEARN FROM THEM..... you're doing good.

I pushed the envelope with this install but am convinced I punched a hole in the membrane with a roofing nail's edge and my "BIG FOOT".

Lesson learned;

"More Care and some new protection pads are needed."

I tried to find a leak detection tool at my plumbing wholesalers and tile outlets but can't find one. I'm sure I have seen them some where online before. We dried out the shower floor with rags and left my fan running in the room this past 30 hours and I will head out tonight to start the repairs.

Nice the client is away so I didn't loose a day's pay today - just my "Night Shift" on my home project...

It never ends.

Why it leaked...

Found the hole!

My fault....

Nicked the membrane with my channel locks - Used my channel locks because I didn't have my baby cresent wrench - looked for the cresent wrench because the socket set was in the shop....




I was so happy with my find I ripped it all out so I can do it right next time.

This is exactly why we check.

If you are in a rush, on a budget or any other number of reasons you may wish to skip this step. What will it cost you in the end?

Your health?
Your kids education fund?
Your new car you wanted?
Maybe even your house.

Is it worth it - no way. No No No...

Flood testing your shower is a very important process to stay away from problems that may arise in the future.

RE: Q: Is flood testing your shower pan really needed?

Contractor already pour mud deck over liner. I have no idea if the flood test was done.

Can I ask him to take the bud deck out ??

RE: Q: Is flood testing your shower pan really needed?

Flood testing is required by code isn't it?? I know for our rough plumbing inspection we had to have the pan full for minimum 24hours... for the inspector to see. I think ours was over 2-3days also.
