Stupid question about automatic water trough

[AmyHack]

I got a fantastic automatic water trough for my birthday which I've managed to connect with a hose this afternoon. Really pleased with it but now I'm sitting at home worrying that the pressure will back up and force water backwards and/or break something. Can anyone tell me if I'm worrying over nothing or if I need to put some sort of valve onto it. I've never seen this type of auto trough used before.

Thanks to anyone more knowledgeable than me!!

Look like a standard plastic field trough with a ball valve. I bought 1 this weekend and the local farmers co-op had just had another delivery of 30+, I'm really surprised you've not seen them used before. I have 10 in total now, 9 connected to the mains with a standard plastic tank connector and pipes and 1 connected to an IBC tank via a hose. Unless you've done something very odd I'm pretty sure you're worrying about nothing.

ETA: Happy birthday

There's no way water can go backwards, the input valve is well above the water height.

Thanks guys, It's the pressure in the hose I'm worried about. As it's connected to the tap via a hose. I suppose I'm thinking it's like having a garden hose with a nozzle on the end. If you close the nozzle but leave the tap on and leave it for a period of time the pressure can push the nozzle off. Or make it leak.

You'll see the trough overflow if it's an issue but I have a half one of those on a pumped water supply and never have an issue with it.

Hmm, well I guess it depends on the strength / quality of the fittings you've used on the tap and the trough connection. My IBC tank setup (using standard hose fittings) is fine but it has less pressure than mains. My mains tanks use field water pipe rather than hoses so have a different type of fitting. If you're worried I'd be tempted to just close the tap a bit to reduce the pressure (it probably doesn't need to be fully open).

Thanks guys! I'll turn the tap down a little bit tomorrow and keep an eye on it. I'm such an overthinker!

It should be fine, depends how it's positioned though. I once filled up a bucket with a hose and my field was at the top of the hill... I left the hose innand went off,
came back later and found bucket empty!! Started to think somebody was stealing my water as there was no way they would have drank that much! Then I discovered it was siphoning itself back up the hose and coming out the other end!

There are regulations over what fittings you can use if you are connecting to the mains, you will need either an air gap or a non return valve.

The trough has the air gap built in.

Is your hose connected to a tap at the other end? If so it’ll be fine, as long as your connections are done up tightly.

I’ve had one for years and never had a leak due to water pressure.

It shouldn't return then so you will be fine

If it is a standard garden hose, it can stretch over time with the pressure. Then it can pop off the fitment at the trough end. The worst that would happen is a

I wouldn't worry immediately, with a new hose, but I would replace it with a more rigid water pipe for the long term.

The worst that would happen would be a wet field, and you would likely see the bulging on the end of the hose before it blew.
