# RoamRig Plumbing 101
## Our plumbing upgrades simplify the Revel plumbing with high-quality, reliable components and a single, intuitive valve. Here's how it works.
Interested in a plumbing upgrade? [Start by reading the FAQ on our blog.](https://shop.roamrig.com/blogs/blog/new-product-roamrig-plumbing-upgrades-for-revels)
The heart of our plumbing upgrade is the water panel, which is located behind the slider on first generation Revels and in the back of 2nd and 3rd generation Revels. We've simplified the four switches to a single valve that controls all plumbing functionality.
The panel works the same for all generations. Watch this video for a quick overview:
### Water Panel Functions
- **City water:** Use a connection to a pressurized city water source for the van fixtures
- **Use tank:** Use water from the onboard tank for van fixtures
- **Siphon fill:** Fill your tank with the onboard water pump
- **Pressure fill:** Use the pressure from your water source to fill the tank
### Filling the Tank
Fill the tank the same as before – water will overflow under the van when the tank is full.
When using a pressurized water source, use a shutoff with a built-in flow restrictor to keep the fill rate moderate. This prevents the incoming flow from exceeding the overflow rate and reduces the risk of pressure buildup that could damage the tank.
### Using the Pump
For any van/RV water system, always turn off the water pump whenever it is not in use.
2nd/3rd generation Revels: use the switch on the RoamRig water panel in the garage or the One Place monitor to turn off the pump. Either switch can turn the pump on/off, regardless of which switch was last used.
1st generation Revels: we do not make any modifications to the switch. Toggling the pump on/off is the same as before.
### Draining the Tank
**1st Generation Revels:**
- Either pull the plug on the bottom of the tank.
- Or set the control panel to Use Tank then run your rear shower (to the ground/drain) or the inside shower/sink with an open grey tank.
**2nd/3rd Generation Revels**
- Either use the drain valve on the bottom of the van:
 
- Or set the control panel to Use Tank then run your rear shower (to the ground/drain) or the inside shower/sink with an open grey tank.
