Plumbing shower in van

[hollyb96]

Hi, I have zero experience with plumbing but need to plumb a simple system to a water tank in my van conversion. I need the shower and sink to plumb to the same tank. I bought a shower waste drain online but the pipe connection is 46mm and I am not sure what size pipe is supposed to go into that? I would assume 43mm but it seems that size is quite hard to find. I think the piping coming from the sink will also be smaller than the shower. Does anyone have any tips on how I can make this work? I have attached a picture of the system I would like to make. Thanks

To be honest, your best bet is someone like Brownhills or Towsure. You are going to need two tanks, one for fresh water, and one for grey water (waste). You will need drains valves to allow you to empty them, and also a valve to refill the fresh water tank. You will also need a water heater of some sort (often lpg gas or electric), a 12V pump for the fresh water supply, and taps with built-in micro switches to operate the pump. Most RV plumbing is done in flexible tubing, as it survives better.
