Installing a vinyl pan in shower stall

Hark

I am installing a vinyl pan in a shower stall with a 2" pvc drain line and 2" shower strainer.. I told the tile guy he has to pre gauge floor before I install my vinyl pan. He says you don't have to, why does pre gauge need to be done? What is the improtance of pre gauging?

pre gauge floor?

New-one on me when using a PVC pan liner.

The strainer usually has an adjustment to alter the depth.

Alway pitch

You must per pitch all shower pans the concrete or tile are not h20 proof. The water after about 3 or 4 showers will leach through and the whole pan. If not pitched will be come a cesspool of water do not put in the pan with out pitching it we some times us roof shingles under 1/2" plywood it does not need to be much but you will save your self a lot of trouble down the road.We have ripe out over 20 pans in the last 3 years from poor installations. Good luck.
