Product Questions

What’s the best way to clean the inside of the water tank?
Question by Jason
We recommend using warm water and baking soda to clean our water tanks.
Answer by Front Runner
I have a slimline II for a 2016 Toyota 4Runner. Can I install expedition rails with the standard mount for this tank? Or will I need the special anywhere-on-the-rack mounts for the water tank?
Question by Michael
Yes! The expedition rail kits will work perfectly with the standard mounts. We have done that installation many times.
Answer by Front Runner
What size is the thread on the outlet? (Bottom corner) And is there an outlet on each side? If so is a plug included to block one off?
Question by Joe dale
Our Water Tank Hose Kit (WTAN014) will accommodate this tank perfectly. The tank comes with two outlets, one either side and comes with one plug and thread size is ½” BSP.
Answer by Front Runner
Can you pressurize this so I can use with a sprayer?
Question by Maurice
The tank was designed as a gravity fed tank and has not been pressure tested. So, while we don't recommend pressurizing, we have had customers use inline pumps to have pressurized water with our tanks. Strong showers for everyone!
Answer by Front Runner
What is the flow rate? My intention is to use this as a shower tank for a heated shower. They range between .6 gallons per minute and 1.1 gallons per minute. Does the cap need to be loosened to allow the tank to breathe? My Slimline II is on top of my tall Sprinter van, which would be a pain to climb the ladder and loosen the cap, then climb it again to tighten it back up.
Question by Randy
We do not have flow rates for our water tanks. This tank is gravity fed tank so as you are aware, loosening the cap will increase the water flow.
Answer by Front Runner
Do you sell a locking cap for the 45 ltr mounted water container?
Question by Peter
While we don't have a 45L water tank (WTAN030), we do have a locking tap for our hose kits that are designed for that water tank. The product code for the locking tap is (WTAN016) and hose kits are (WTAN014) (WTAN029) .
Answer by Front Runner
Can you daisy chain 2 or more of these together ?
Question by Zach
Yes, It is possible to daisy chain the 45l water tanks. We recommend using our hose kits.
Answer by Front Runner
What is the overall dimensions with the bracket shown in the picture ?
Question by Jonathon
370mm (W) x 370mm (H) x 575mm (L with brackets).
Answer by Front Runner
Hello, does this tank with the mounting system, fit on the JK 5-door interior rack?

Thank you.
Question by Pol Clement
Yes, the water tank fits on the JK 5 door interior rack.
Answer by Front Runner
Question by stopbit
This tank will mount to the interior tray yes. Because of the limited space, mounting and filling the tank is not as easy as a roof rack mount however.
Answer by Front Runner
Does the mounting system work on a stock toyota fj cruiser roof rack?
Question by mbahl
Unfortunately no, the tank was designed to be used with the Front Runner rack.
Answer by Front Runner
Can this attach to the Slimline I rack?
Question by Puneet Bhalla
Yes you can. You will need to buy this adapter for the Slimline I.

Fantastic Review by Lexusallterrain
A very easy to use water with lock, no leaks, keeps water warm enough in summer for evening shower. Very convenient safe way to transport water ! Easy installation! (Posted on 18/10/2017)
Great Rooftop Water Tank Review by Paul Eric
Love this tank. I have it plumbed to a small pump providing pressurized water for showers as well as general camp wash down of items. The one thing I wish it had - a handle. This tank is heavy when full. Yes, I fill it while mounted on the rack whenever possible. But, with my entire camp depending on my vehicle (roof top tent, awning, shower enclosure, etc.) I don’t want to break camp just to refill this tank. When full of water the tank weighs approx. 100 lbs. Typically someone will hand the full tank up to me as I kneel on the rack and lean over the side. We make it work. (Posted on 15/10/2017)
