Apprentice Electrician

Yes I got to be an apprentice electrician the last few days, as we are setting up the wiring for a hot tub. So I have pushed and pulled 3 wires through 3/4" inch PVC pipe and glued all the 90* angles and couplers to the pipe and laid it by the house starting from the electrical box around the outside of the fireplace to where we want the hot tub on the patio. DH calls to let the hot tub people know the wire is in place and they say they need 4 wires. Now DH is getting upset and doesn't want the tub---I really didn't want one as it is one more thing I have to take care of. We had a tub when we lived in Beatty for a year and sold it before we moved. I used it but DH went in it maybe 3 times. Now we are waiting for the electrician to call back.
