Pocster Posted March 25, 2021 Author Share Posted March 25, 2021 SWMBO was over again ffs Current plan is this . Macerating WC pumps ? into grey water macerator which then dumps into soil pipe . Meanwhile sink/washer etc. grey water uses a seperate pump . I’ll put valves on both vertical runs so I can avoid grey or ? running Back when they break ( not if ) . I’ll set a zwave sensor on macerator that receives the ?. So at least if it doesn’t trigger I.e draws too little current or indeed too much than at least HA can inform me . I’ll probably put a valve on the input pipe . So when it busts can turn inlet pipe and outlet pipe off . My other plan was when it fails I see no reason why I can’t drill a hole straight into the saniflo unit to drain it of ?. Trying to minimise the fun when it goes wrong . Apart from relatively easy access to the pumps any other suggestions to take into account when failure strikes ? Link to comment Share on other sites More sharing options...

PeterW Posted March 25, 2021 Share Posted March 25, 2021 Don’t think a grey water pump will accept black waste - you will need a pair of macerators and block the WC connection to add the feed from blender No.1 in to this ... Link to comment Share on other sites More sharing options...

You’ve confused me wc has a ? macerator which then pumps to the first grey pump ( making it not grey anymore ? ) - then up and out ( hopefully ) Link to comment Share on other sites More sharing options...

Which is the point I was making. Grey water saniflo are just a pump and a float switch in a box. WC waste is known as black water and contains solids. Different type of pump.

Pocster Posted March 25, 2021 Author Share Posted March 25, 2021 The horizontal pipe at the top that goes into the soil pipe . Should both outputs go into that 1 pipe ? . Or better to have a independent pipe into the soil I.e 2 horizontal pipes Link to comment Share on other sites More sharing options...
Pocster Posted March 25, 2021 Author Share Posted March 25, 2021 Can you get a cap to seal off the toilet standard waste input ? ( that’s what you meant @PeterW I assume ) . Link to comment Share on other sites More sharing options...
Pocster Posted March 25, 2021 Author Share Posted March 25, 2021 Should the pipe run from wc macerator to black macerator be a larger bore ? . My logic being if black macerator blocks ( for example ) the pipe will hold the contents . Or am I overthinking it now ? ? Link to comment Share on other sites More sharing options...
Pocster Posted March 25, 2021 Author Share Posted March 25, 2021 Thinking about it . if the vertical black pump pipe is full of ? and it fails would you be able to turn the valve to isolate and stop it running back ? . Trying to think of a guaranteed way to isolate or even drain the pipe in a “nice” I.e controlled way . Link to comment Share on other sites More sharing options...
PeterW Posted March 25, 2021 Share Posted March 25, 2021 So these can take a standard 110mm waste pipe which you can cap off and then run a 38mm pipe or similar into them. That needs to be as short as possible but also your input pipe needs a fall on it, especially if it has just a WC feeding it. You’ll need to come up out of the macerator by a foot or so then get a decent slope to the next one. Not sure if this will work in reality and these things are noisy - one is bad enough, a pair running ...??? Have you not had the sensible conversation and said the “No” word to Mrs Pocster or is that something that is banned in the dungeon ..?? Link to comment Share on other sites More sharing options...

Mr Punter Posted March 25, 2021 Share Posted March 25, 2021 I fitted one of these into a basement: https://www.sumpsandpumpsdirect.co.uk/acatalog/Sewage-Pumping-Station-Compact.html#SID=20 No noisy macerator and uses heavy duty 2" ID pipework. I sunk it halfway into the ground and brought insulation and flooring up. Located in a services room behind the WC. Link to comment Share on other sites More sharing options...

I know that’s what I need . My question would you be able to turn it with 3m of ? vertically stacked ? . Would it turn ? . Pressure too much ?

Pocster Posted March 25, 2021 Author Share Posted March 25, 2021 This type of thing for the black macerator . Block the conventional inlet and use a low one ( so I get the fall from the Wc macerator ) https://www.plumbworld.co.uk/flo-force-max-macerator-pump-101425-1252355 Link to comment Share on other sites More sharing options...
Gav_P Posted March 25, 2021 Share Posted March 25, 2021 Does the Macerator have to be right next to the bog or can you use normal soil pipe from the bog to the macerator which located somewhere else? Link to comment Share on other sites More sharing options...

No. Because the liquid will run ahead of the solid from the WC. So eventually you will get a blocked pipe. Saniflo confirmed this method was a bad idea.

We've established it is possible with some "risk". The other thread you refer to is Zoot the Hoot. I believe he has immigrated to a warmer climate.
