New Shower Drain


1/2" will be fine---when you pack the deck mud for the preslope ,fill in under the drain flange.---this will give you a stable footing for the drain.

I am not planning on chipping out and replacing the cast with pvc. As far as I am concerned that is asking for trouble especially being that I do not have a basement to go in and look where the cast ends. I feel that that the direction I am headed & the work I have done is ok to this point.

So is anyone willing to answer my original question of is 1/2" ok??
Asking for for trouble is leaving that cast trap in the ground, trouble is a clogged shower down the road and a cable going through the weakest part of the drain after ex amount of years of use, the base of the trap, guess what needs to get done now.

You will not be sorry if you replace it----leaving old parts under a new pan is not a good idea.

New Shower Drain


Well... Did the preslope, and put the liner in but I am concerned about how I cut the liner a bit wide around the drain. I put the silicone under the liner and bolted the flange down. Should I be concerned??.. Would appreciate opinions.. Thanks guys..

Who did you attach the PVC part to the cast iron part?

Considering you are on slab..... yes 1/2 inch should be ok for the pre-slope slab at the drain.... I like 3/4+.... but you are on slab and I think you'll be fine.

Just my opinion.

EDIT:Sorry did not notice this had a second page to the thread and the question had been answered.

I believe your hold down plate is going to cover that hole and make a seal...... try putting it on

A fernco is like a radiator hose. It also is not the approved way to connect from cast iron to pvc pipe. A transition coupling made for your connection from cast to pvc would have been the right way to do the job.

Also make sure you block the drain and water test up to the top of your shower threshold. Let it sit for a few hours. There should be no leaks or wet wood around the shower if your liner was done right. Make sure you read the liners install instructions a few times over and over. No nails within 1 inch of the top of your threshold. No nail through the top of your threshold the liner should wrap the threshold and be nailed on the outside front.

If you nail the liner on the top of the threshold water will leak into the wood and it will rot. In about 6 years you will get to do it over again.. It was a common error I noticed when we had to inspect liners. Water runs down your door through the grout and down the nails. Water will find a way out if you give it a way.
