Can't help in person but here's some tips:
1. If using a union, make sure the circle/cuff connector is on before gluing the other side
2. When gluing a fitting to pvc - Push in and turn, then hold for 15 seconds
3. Buy 1-2 extra fittings, particularly unions, 90's, 45's, and even throw in a coupler or two just in case. I really can't stress this enough. I ran into mishaps and had to wait just to continue progress due to orders and shipping
4. Savko is an excellent source for parts
