Bought a granite bath top- my centerset Moen faucet – new- the two feed pipes are supplied with a spin on plastic nut to go under the counter. it is a real thick plastic nut- that plus the thicker granite leaves only 3 threads for the flex couplings to screw onto.
should the granite people have thinned the granite where they drilled the holes (or does that weaken the granite) or is it better for me to go out and find thinner under counter nuts?
Mone never heard of granite I guess

You may want to contact Moen & ask for an extension bit (not sure of the correct verbage). I know the plumbing company that I worked for had them for thicker granite installations.
And make sure to get enough of them (one for hot & one for cold etc).

How thick is that top?
john 3 cm I think thats Canadian I think. In merica talk its a little over an inchbought at a good faucet store, not lowes
sales lady "has never heard of the problem" with granite
parts man tried to sell me a $35 extension kit.
Ace also sells 3/8 inch plastic screw on "nuts" for $1 each.

Nearly all granite in the US is 3 cm (roughly 1 1/4") but in the trade the stoneyards definitely refer to it as 3 cm.
This is a common problem and lots of plumbing manufacturers haven't addressed it adequately (even Kohler - they still have plastic nuts on some hand sprayers). They don't *get* the seriousness factor of an undermount tub installation with granite over and tile down to the granite, not to mention waterproofing, etc. Everything below the tub deck has to be bulletproof and unbreakable.

You may have already had your question aswered, but you will probably need to find an accessory kit to your faucet for thick slab applications.
Most of the manufacturers held onto their old designs for residential applications and created "kits" to handle special applications.
Moen has heard of granite, they just had already contracted to have about a million units produced at the level that they were expecting before you decided on a different situation.
I am sure that Moen has not heard of you. ;)

Basic problem is that Moen is ignoring granite. I used the old 19 year old heavy brass 1/4 inch "nuts" they worked. the new cheaper plastic nuts to be as strong need to be 3/4 inch thick- that plus Moen putting on short pipe stubs causes the problem.Home free? not really, the extension drain pipe that screws into the pop up assembly is too short by 1/ 2 inch so back to the store.
