Liquidtight vs pvc conduit

[Eaglei22]

I saw the liquidtight conduit at my local hardware store, which had a continuous 100ft roll.

I am just a diyer laying electrical for a dedicated pool pump circuit, and also a general use. Which will be about 75ft away from house.

I want to run two seperate 12 guage wires in that tube and two neutrals, and one ground (or would two seperate ground be better?) ?..

Looking at the liquid tight it seems more straight forward and adaptable to the trench angles, better than pvc conduit.

Pvc conduit shows a burial depth of 18 inches. What is the depth for the liquidtight conduit?

Also, does the liquidtight cable need to connect underground to a pvc/metal conduit? Or come right up to the junction box before entering the house, or come right up to receptacle housing. If connection underground, how is a waterproof seal made?
