Neighbours pressure washer

[Galaxy88]

Please help me with some suggestions and possibly grow a back bone

My neighbours are outside currently pressure washing their drive. They do this frequently, at least every few months.
This in itself is not a problem, but the drive is shared and the mud and debris floods our side and down onto our patio and under the garage door (where we keep all our outdoor electrics and tools)

Everytime they do a wash, we spend ages cleaning out the flooded garage and all the rubbish off the patio.
I dont know how to approach or fix it, the drive is angled downwards and the drain at the end of the drive cant handle that much water in one burst, so floods a few inches into the garage.
Aibu to ask the neighbour to do this in small stages? I think I need to invest in sandbags. I hate getting this frustrated over a pressure washer, but it floods our garage that is on the end of the drive.

Generally they are lovely, but seem obvious to the hours of work they cause us in clean ups after each wash.

Will be looking at a guard! Cant keep doing this every 3 months. No, the garage doesn't flood when raining. The drain in front of the garage handles rain water fine so far. Just not industrial pressure tools that are currently being used.

To be fair it sounds more like a drainage problem, which is your responsibility not your neighbours'. The paving and garage floor should be laid on a slight incline so that water runs away to a drain that is able to cope. What happens if it rains heavily? A pressure washer doesn't actually produce a huge volume of water, certainly less than heavy rain over the area of a drive.

Sorry, cross-posted!

Ring your insurance company and ask for legal advice.

Maybe if you go and ask for their insurance details as your insurance company will be claiming for all your numerous ruined electrics they'll stop and think that the consequences will effect them too

Tell them, and ask them to stop or at least to do it so it doesn't flood your drive and garage. They probably have no idea.

We have a neigbour who used to do this, until we told them they were soaking the fence and our patio. They also had no idea, and are now careful were they spray!

It's not your regular pressure water, its larger circular style one that's pushed along the ground rather than held and sprayed. Drain is fine with rain water, had no.issues so far.

They clean stuff by virtue of the pressure of the water they spray, not the volume of water. The bigger the machine the higher the pressure. But if it's just connected to their outdoor tap it can't produce a greater volume of water (as in litres per minute) than the tap itself will provide.

So, I'd say that either the drain isn't capable of coping with the volume of water which a running tap on full blast will produce (which suggests it's inadequate), the paving slopes the wrong way, or whoever is doing the washing is blasting it against your garage door and forcing water under it that way.

This is 2.5 meters wide, is that enough for your garage?

I'd send a solicitors letter to the NDN's, saying that they are damaging your property with their actions and it needs to stop!

Fiddlesticks that's not true. I live at the top of a hill. If I pressure washed my paving, it would cascade over the wall into my neighbour's garden because it's lower than mine. So I don't use a pressure washer because I'm not an arsehole.

It is the responsibility of the person doing the pressure washing to ensure there's adequate drainage on their property or via public drains. It shouldn't be affecting the OP's property at all

Ring your insurance company and ask for legal advice I suspect that's the best bit of advice on this thread, OP.
