Help with plumbing!!

[BenHulland1234]

Hi, I am a complete beginner when I comes to reefing, i’ve had freshwater tanks in the past but have decided to take the plunge into saltwater, I have purchased a new tank which has 2 holes to drain into the sump, and one hole for the return. I live in the midlands in the uk so the only plumbing/diy shops I have local are B&Q, Wickes, plumb centre and city plumbing. I am after some help with the whole plumbing, I have no clue what to buy from bulkheads to pipes to fittings, and how it’s all put together!
All 3 holes are in the side wall of the tank near the bottom, behind a wier.
The two drain holes are 1.75inch
The return hole is 1.25inch

Thanks in advance for any help!!
Ben

Check this out... it will help you determine which bulkheads fit into the hole sizes in your tank. Good place to start...
