Best way to seal around garden drain

[DIYJoe89]

Hello
I would love some help if anybody has any suggestions please

I have attached a picture of our garden drain, we have had a little bit of damp in the kitchen around the window above this which we were advised was due to the guttering which we have had replaced and that seems to have stopped it

I am looking for the best way to manage this drain which I think also can't be helping. The water appears to be coming at it too fast and it splashes everywhere up the wall, is there some sort of splashback I can buy to prevent the bricks getting constantly soaked? Or a better idea? Leaves are cleared now.

I am aware I need a new pipe for the kitchen sink drainage (I snapped it last night). The expanding foam around that pipe is very damp, should I replace that?

Planning to re-point the bricks this weekend.

Thanks for any tips or advice, really appreciated!

You can use a drain cover like this

to reduce the splashing. That is just an example.

As your RWP is in the corner you may need to use a couple of bends

and a bit of pipe to make it align with the hole in the drain cover.

Also you can get a gulley grid

FloPlast Gulley Grid Black 150mm x 150mm - Screwfix

Order online at Screwfix.com. Black polypropylene gully grid with downpipe knock-out section. For connecting downpipe directly to underground drainage section. Compatible with Polypipe, Hepworth, Osma, Hunter, Marley, Brett & Marshall Tufflex. FREE next day delivery available, free collection in...

that is made so that you can knock out a circular piece and put the end of the RWP directly into the gully.

You would need to make sure that a new gulley grid will fit.


For the kitchen sink drainage, I think that you will need to replace a section of it, and to get the bit that goes through the wall free you will need to remove some of whatever is around it. If that is wet then removing it will remove water from the wall.

Pipes like that outside become brittle with time as the plastic (PVC) degrades under UV light.

EDIT:
The hyperlinks to Screwfix do not work, but if you copy the text to a new tab that does work.

^All good advice^ and i'd suggest you also apply a fungicide to the algae on the wall, do a bit of pointing then brush a water sealant over the whole area to maintain the bricks. Look into getting a drain leaf guard to stop the cover getting blocked, too.

Extend the down pipe through the grid so it discharges below ground level.
