Frequently Asked Questions

SealStop is a portable, completely mechanical automatic water shut-off valve. Simply attach it to your
garden hose, position it on your bucket, trough, watering can or container and turn on the tap.

SealStop automatically stops the flow when the water reaches the correct level, so there's no need to stand and watch it fill.

SealStop uses water pressure and a clever mechanical valve to automatically stop the flow of water.

There are no batteries, electricity, timers, apps or Wi-Fi required. Just connect it to your hose and let
SealStop do the rest.

Yes. SealStop holds UK Water Regulations certification under Regulation 4, Fluid Category 3, certificate number 2603716(1).

This means SealStop has been independently tested and approved for connection to a mains water supply.

SealStop connects to a standard ½" garden hose using a standard hose-end quick connector, such as a Hozelock-style fitting. We recommend using a good-quality Water Stop hose-end connector for the best performance.

Your tap itself doesn't need any special fitting beyond whatever you normally use to connect your garden
hose.

SealStop fits most buckets and containers, from thin flexible trugs with rims around 3mm thick, right up to galvanised troughs with rims around 70mm wide.

For standard buckets and thinner containers, the rim sits within the groove of the SealStop holder. For wider rims, such as troughs, the rim sits between the valve and the hose instead.

Always remember to clip your hose into the holder. This helps support SealStop and keeps it correctly
positioned while filling.

SealStop also works with many watering cans, although those with very low handles can be a bit of a
squeeze.

Not sure if it will fit? Send us a photo of your container and we'll happily take a look.

Yes. SealStop's holder has been designed to sit securely over the rim of most standard buckets and
containers.

Different shaped rims can affect the fit, so if you're unsure whether SealStop will fit a particular container, send us a photo and we'll be happy to advise.

No. SealStop is completely portable and requires no tools or permanent installation.

Simply connect your hose, position SealStop on your container, clip the hose into the holder and turn on
the water.

SealStop is designed to work with mains water supplies between 0.5 and 5 bar.

If your water pressure is below 0.5 bar, the current SealStop may not operate correctly. If your pressure is
above 5 bar, it should be reduced before using SealStop.

Looking for something for a water butt or other low-pressure supply? A low-pressure SealStop is currently in development. Get in touch to register your interest and we'll let you know as soon as it's available.

No. SealStop is designed for use with cold water only and should not be used with hot water.

Yes. SealStop is designed for outdoor use and can be left outside during normal use.

To prolong its life, we recommend storing it out of direct weather when it isn't being used for long
periods.

In freezing weather, disconnect SealStop and store it somewhere frost-free. Water left inside the device can freeze and potentially damage the internal components.

No. SealStop is designed for outdoor use only.

Yes, that's exactly what SealStop is designed for.

You can leave your container filling while you're nearby getting on with other jobs, without the mad dash
back to the tap before it overflows.

SealStop will automatically stop the water when your container is full. However, it is a portable filling
device and isn't designed to be left permanently connected as a 24/7 shut-off valve. Do not leave unattended with livestock.

Once you've finished filling, simply turn off your tap and move SealStop onto the next job.

SealStop can work with some pumps, but the pump needs to be suitable for use with a shut-off valve and able to stop or safely handle the back pressure created when SealStop closes.

If you're unsure, we recommend checking with your pump manufacturer first. You're also welcome to try SealStop with your setup and, if it isn't compatible, return it to us within our 30-day returns period.

Yes. SealStop is used on farms, yards, stables and smallholdings and is ideal for portable filling jobs such as buckets, troughs and other containers.

The current SealStop is a portable filling device and is not designed to be permanently plumbed in or
used as a 24/7 livestock trough valve.

We offer a 30-day returns period so you can try SealStop with your setup.

SealStop also comes with a one-year guarantee.

Yes. Every component of SealStop is available to buy separately as a spare, so a worn or lost part doesn't
mean replacing the whole device.

Get in touch and let us know which part you need and we'll point you in the right direction.

We don't currently offer international shipping directly through our website. However, we do have retailers in a number of countries.

If your SealStop isn't shutting off correctly, there are a few simple things to check:

1. Make sure SealStop is sitting correctly and vertically on your container.
2. Check the diaphragm is seated correctly with the clamp ring positioned on top.
3. Check the rubber stopper is present and correctly positioned.
4. Make sure the device is properly tightened and hasn't jumped a thread when being screwed
   together.
5. Check your water pressure is between 0.5 and 5 bar.
6. Check inside the device for any dirt or debris that could affect its operation.
7. Make sure the hose isn't pulling or twisting SealStop out of position, and remember to clip your hose
   into the holder.

If you've checked all of the above and you're still having problems, get in touch with us and we'll help you
troubleshoot it.

If no water is flowing through your SealStop, check the following:

• Make sure the top thread hasn't been overtightened.
• Check that the diaphragm is seated correctly and hasn't moved during assembly.
• Make sure you have sufficient water pressure. SealStop requires a water pressure of at least 0.5 bar
  to operate correctly.

If you've checked these and it still won't start, get in touch and we'll be happy to help troubleshoot.

If SealStop appears to have shut off but you notice the water level in your container is slowly continuing to rise, there are a few things to check.

Turn off your tap and disconnect the hose first. Then take your SealStop apart and make sure the diaphragm and clamp ring are correctly seated and creating a good seal.

Check that there is no dirt or debris preventing the float from sealing correctly, and make sure the yellow
hose connector is screwed on tightly.

Reassemble SealStop carefully and test it again.

If your SealStop has previously worked correctly but has started becoming intermittent, it may simply need a clean.

Turn off your tap and disconnect the hose first. Then take the device apart and clean the components
using a 50/50 mixture of white vinegar and water to help remove any dirt, debris or limescale. Rinse with clean water and reassemble, making sure all components are seated correctly.

Taking SealStop apart to clean it does not affect your one-year guarantee. We actively encourage regular cleaning, as it keeps the valve working at its best.

When testing it again, make sure SealStop is sitting upright on the container and that the hose isn't pulling it out of position.

If you're still having problems after trying these steps, get in touch with us. We're always happy to help.
