The pictured drain gets blocked periodically - everything drains into it - shower, bath, all sinks, dishwasher and washing machine so every so often I need to clear bits of hair and food out of it (I realise it could do with a good repoint!).

Today it's really blocked - I've ladled all the water out into a bucket but the blockage is further down - I've poked a thin stick through the grate and can feel that it's silted up so I thought it would be a simple matter of lifting off the grate and getting my hand (gloved) down there but the grate seems completely solid. I thought it would come off to allow access to the clay pipe but could it be cemented in place? I don't want to pull on something I shouldn't be pulling and end up with a real mess.

I'm fairly certain that it's a problem with this drain specifically rather than anything further down. but if I can't get this grate off is there anything I can buy to help get rid of the blockage? I was looking at the 'drain snake' type things at toolstation/screwfix but they seem to be for indoor blockages.

Any suggestions much appreciated.

Yes grate must come off - if you've got a sharp HSS metal drill then drill through the edge of the cast iron next to a slot - do 4 like a cross , then 1 in the middle . Then whack it hard in the middle , it should break . Let us know here how it goes (y)

Won't the grate lift up and off, using a couple of hook tools? Probably need a bit of persuasion.

Thanks both. I'll try hooking it out before drilling.

It looks like the PVC pipe is in the way a stopping the grate from being lifted up . you might have to cut around the pipe or maybe replace they are cheap enough mainly of PVC these days .

Looks like someone has used some black sticky stuff and stuck the grate down. A bit of force should release it.

First off, check for a local manhole(s) for a blockage, otherwise it’s pointless trying to half clear something. The grate should come off, I don’t think anything has been used, I’d say that’s just grease buildup. If the manhole(s) is clear, the I’d be using a drain rod with rubber /plunger disc on, looks 4”.

Thanks all. I eventually got the grate off with the help of a couple of pan hooks stolen from the kitchen. Once I knew it was intended to be removed I could pull appropriately hard! I cannot believe how much was stuck in that drain, a bucketful of foul smelling decomposing waste. Thank goodness for long long gloves. There was a plastic bag down there, goodness knows how but we've always had issues with our dishwasher so maybe it's been causing issues for a long time.

Shower time now. Thanks again.

Why wreck it?

It will simply be stuck with debris. Find something like a metal coat hanger, with the end folded to form a hook, hook a corner on the grid and pull it up.

A wet vac, if you have access to one, will suck out the mess at the bottom, then try flushing with plenty of water until clear.

Did you get sidetracked Harry or not read the last post? ;)
