Ok so I don't apply pipe dope to the threads of a tub strainer before you screw it into the shoe of the W/O assembly, One plumber that works with us says a engineer told him it needs it, let me say one thing here, where it threads into the shoe of the drain is not where a seal takes place, dope is not needed there, the seal is at the gasket and the putty. Who here puts dope on those threads?

 

[Bill]

Agreed, and even if it does manage to drip a bit it should wind up inside the tub shoe anyway. But yes, I agree the seal is with the rubber gasket underneath, and the putty on top. Though I started adding tub/tile caulk around the basket after I tighten it just to be sure.

Rectorseal T plus 2

 

[Wethead]

I never have dopped the thread ever,

Its NOT the threads that make the seal,

 

[ROCKSTARPLUMBER]

T + 2 use it on all the strainer threads. Found that i have had less leaks for some reason that way.
But, i have seen some guys put dope on a toilet tank gasket. Ex-boss told them to do it. Never understood that one. i see dope all the time on things that dont need it. water heater flex connectors, no burst supplys, true sign of a rookie.

I have seen guys put teflon tape on a union......come on now

 

[Ron]

He told me it makes it screw in better, ha, there not even a tapered thread, I showed him, I go, watch this, see how easy it screws into the shoe, he was not convinced it was not needed, so I told him do what he likes, it won't change my way of doing it.

 

[ROCKSTARPLUMBER]

I dont have a can of it in front of me, but isn't clearly printed on the label of all dopes, that it is just a lube, not a sealent?

Never thought of it, but you are 100% right, it is NOT a tapered thread!

Plumbers faucet grease on the threads.

One of you service guys will thank me for it later when you can easily disassemble it.

Is it harmful to ABS of PVC, just asking cause I don't really know.

 

[Wethead]

Prolly not , I use something similar on pools

No.

I use brass Gerber pop-ups.

 

[Wethead]

No.

I use brass Gerber pop-ups.

You know, off topic here , BUT for years that company GERBER always reminds me of baby food

 

[Ron]

Cool, not that I'll start using it, only time I thing I might use it is in an all bass application, but I see no seizing of the threads in a plastic application.

i think you're right and that's why i use it sometimes. i will use it on a tub strainer if the shoe is brass as an anti-seize. i can't remember using it on abs ones though.

i use faucet grease on all sorts of stuff for this same reason and i am a service plumber!! if i'm doing any service plumbing in Il, i'll thank you in advance right here. it really does make a difference. i put it on delta shower valve domes when i rebuild the valve and they aren't frozen up for the next guy.

I put Dope Megalock on mostly every thread i make up.. I put it on the tub thread just to make it screw in smoother.. Just a habit ..

 

[Wethead]

Yea, the MEGA lock is BIG Apple thing for sure

When I plumbed in other states it was Hercules Dope

 

[Kyle181]

i use dope on the strainer threads, i fell like it threads in easier, and thats the way i was taught to do it so ... its just habit now

The reason for dope on a tank to bowl gasket is so it can seat easily without the binding that a dry gasket occasionally encounters. It's not a big deal but it's just one of those little things that makes it all easier and better.
