Graf Rain Barrels - Water Harvesting Products and Accessories

Hi Wade,

The slatted wood rain barrel has a 92 gallon capacity, the brick version is 105 gallons.

The barrels may be connected together with an overflow tube at the top to overflow to subsequent tanks.

We currently are extremely limited on our rain barrels due to warehouse space constraints and we do not have either of these models currently in stock. We can order them, leadtime would likely be about 8 weeks. Additionally, these would need to ship via freight truck due to their dimensions.

Thanks

Hi Victoria,

The hose bibbs/taps that are included with the rain barrels have metric threading and a tapered piece to which you can attach a standard American garden hose by trimming off the threading and attaching it with a hose clamp. The other option would be to just use rubber tubing to attach to the nozzle. We do not have any attachment that allows you to thread an American hose onto the metric threaded spigot.

All of our rain barrels come with the diverter kit in a rectangle shape and a spigot.

Hi Cathi,

Thank you for your interest in our products. The rain barrels come with a downspout diverter kit which includes a hole saw. This is used to insert the diverter into the downspout and also to make an inlet into the barrel. The barrel comes without an inlet – allowing it to be placed on the location that works for you.

Please let me know if you have any additional questions.

Hi Amy,

Thank you for your interest in our rain collection tanks. We currently do not carry them in stock, but they can be special ordered with our next container from Graf.

The main tank does extend down to the bottom – which is below the spigot. It is sufficient to leave the spigot open during hard freezes. However, if you would like to be able to drain all water from the tank, you can purchase a universal water removal kit to add an outlet at the bottom of the tank. Additionally, this hose is clear and can be used as a gauge to see how much water is left in your tank.

Hi Tuvien,

Thank you for reaching out. On a 2” x 3” downspout, the diverter should be inserted on the 3” side. There is an appropriately size hole saw to cut the hole needed in the downspout as well as the tank.

Hi Gregory,

The spigots on our rain barrels are not threaded for a standard threaded hose to be attached. If you are wanting to attach a hose, we recommend cutting off the threaded end of your hose and attaching it over the tapered nozzle with a metal hose clamp.

If you are using a soaker hose, please be aware that water flowing out of a rain barrel is only flowing based on gravity and will not have the pressure of a hose connected to a spigot. There may not necessarily be enough pressure for a soaker hose to work as effectively as if it is hooked to a regular water supply.

You can increase the pressure some by raising the rain barrel up so your gravity flow is better, or you can also use a transfer pump if desired.

Hi Jeff,

The Brick Wall and the Slatted Rain barrel are similar in construction. When you receive them there is no inlet – but the downspout connection kit that is included comes with a hole saw for you to place the hole at the best location for your placement. So then you will have a the inlet and the spigot. There is also one additional hole at the bottom of the tank that comes with a threaded plug – front bottom left corner on the Brick Wall Tank and bottom side on the Slatted Wood Tank. This hole is used for draining the tank completely, as the tank does extend fully to the base. However, it does have the same threading as the spigot, so people have occasionally moved the spigot to the lower position and raised the tank up to make it usable.

Hi Shirley,

First you close off the intake valve – so no more water enters the tank. Then you leave the spigot/tap open: leaving enough open space in the tank to allow the left over water to expand when frozen.

Very little cleaning (if any) is required due to the way the intake water grabber is designed – it really only collects water coming down the down-spout and hardly if any debris. But the biggest reason for little debris is that because the tank is closed to light/sunlight the water doesn’t degrade and does not develop algae – it stay clean – as a result there is very little settlement developing at the bottom of the tank – therefore not needing any cleaning. But just in case you do have a pretty bad/old roof with lots of material run off you can buy a special “universal Drainage Kit” which would allow you to drill a hole at the very bottom edge of the tank and drain debris.

We have added the Top Tank to our line of Graf water harvesting products.

They are 1,300 liters about 340 gallons. These are a bit more industrial looking but they are very high quality – and because they are made of two halves of high impact plastics this unit is 10x easier to move around than any other unit made from one piece and/or steel. Empty the unit only weighs about 70 lbs.

Yet they are too big to send by UPS/Fedex and will have to ship on a pallet – but they nest very nicely – so the more units we ship the cheaper the cost per unit. We can ship 8 units on a pallet.

Hello, Thank you for visiting our website.

Yes, it will work just fine. However, if you want you can instead buy a much bigger collector but they are much more expensive.

FYI: most customers do not realize that 1” of rain on a 1,000 sq.ft. roof produces about 670 gallons of water - yet your rain barrel will hold only between 50-120 gallons so you only need to catch 20% and your rain barrels is already full.

Hello, Thank you for visiting our website.

Unfortunately we do not have the Sunda in grey, only in the dark mocha color. The "grey" is a typo on our website, apologies for that. The Terranova wall tank is available in gray and is the same size and shape of the Sunda. It features a real nice rocky/concrete looking texture.
