Shouldn’t stick your part and hand in small holes …

Perhaps when it’s dark stick a torch outside so you can see the light coming under the dpc . Foam along until no light visible . You’ve then done the best as possible .

Unless you can see right under there it will be tricky to fill with ct1 . Expanding foam is best . As said ; won’t stop water entering ( in a flood situation ) but will stall / slow it down . 👍

Crumbs you were unlucky . Yes a decent channel and also a decent water ‘storage ‘ facility ! . Still think expanding foam is best under there to seal it properly. That doesn’t mean of course water couldn’t get under the dpc if it flooded again though . Get those 2/3 pumps in and some method of high water / pump failure alarm in pronto !

Been pissing down here now for about 5 days! But yes ; this is what I have. My concrete courtyard slab with a channel ( shuttered before concrete pour ) in front my sliding doors. That 'channel' continues the full with of the doors and then turns 90 degrees straight into my sump 'chamber' ( another concrete cast ) which is of course lower ; that is where my 2 rainwater pumps sit. My courtyard is also ( deliberately I may add ) quite a bit lower than my door threshold. I have plastic stilts and aluminium joists with decking on top . What this does mean ; if both pumps fail for whatever reason I can 'store' a lot of water before it even gets near the doorway. I'd do a photo also ; but like you - I'll get drenched 😎

If it’s an awkward ‘gap’ then I would say expanding foam . Is there not a drain / channel outside infront the doors ? - that is what you really need that feeds into your sump . add: photo of your doors / courtyard from outside might help

HomeSeer is your answer . Convoluted and sometimes contradictory. Multiple ways to solve the same problem . Big user base ; so lots of help . Lots of bitching aswell . HA is not home assist @Radian .

Small fry

This is the thing . How far do you want to go ? . I have 4 pumps ( each pair on seperate outlets , battery backup , audible alarm , HA alarm on failure ) . What is the probability of 4 pumps failing and zero electricity- it’s pretty (expletive deleted)ing slim . But you’ve been flooded so your attitude to this risk ( as it has happened ) will be less .

Tricky ; especially on this forum . Most here are mentally average at best but obese in size .

Sorry ! Re phrase “ Turn off my SWMBO “ - what’s the male equivalent of SWMBO ? ( going to Google that now ! )

Turning SWMBO off

Think of all the energy we / I waste by posting . I heard a rumour that @Onoff ‘s bathroom thread consumed over a gigawatt…

Geniushub is good - I’ve used for many years in 3 properties. Certainly worth a look

Doesn’t “look” legal ! . Can’t imagine that’s allowed!!!

SWMBO will want one - so accept your destiny to install one

I know you potentially were planning to have a basement WC … If that happens and possibly showers , another WC ( no idea of your layout / plans ) then a sump for all of this might be better than a macerator “ per thing “ as it were to pump up into the internal drain pipework . If had to add the sump all for the sake of a basement WC - pita ….

Excuse me ! ” To add My rainwater Zoellar pumps are at 2 different heights in a pit I.e lower than my basement floor . “ nuff said bro 😎

I have something similar for my sewage pump . It can’t overflow of course unless both pumps fail and high water alert fails . Rainwater is of course the real issue - here I just have my 2 pumps at different heights in a hole in my concrete slab . A ‘ service agreement ‘ is BS 😁

I’m not sure there’s a lot to actually design here . Obviously speak to a sump seller - but at the end of the day it’s a couple of pumps in a container with an outlet to the drain . Making an insurance claim on failed pumps that you design / install yourself though could be an issue . Depends on your attitude ( confidence? ) on this issue .

You mean THE Kevin? You don't get paid ( I checked on that years ago ). Also I don't need some condescending , (expletive deleted) wit bitching at me about how I will fail and how bad it all is.

Swmbo narratives on HA.... " well it didn't work yesterday! " " if you die how will I fix the music player ?" " is that camera working?" " I hope you know what you are doing " " the rooms cold are you sure your heating system is working " etc. etc. etc. etc.

Trust me I would. Got a bloody house to build haven't I !!!

You’re the only one that visits . You just want a pir light so you don’t fall and break your neck . Oh yes ( as you can imagine ) (expletive deleted) the neighbors

Mines the same . 99% HA is not good enough . As we know 100% is impossible.
