oddjob Posted August 16, 2020 Share Posted August 16, 2020 Hi all I'll be digging a trench to the shed to get electricity out there and thought if I add a water drain while I'm at it I would be able to use the shed for my home-brewing. I checked with the sparks and he had no issue with the water and electricity sharing trench ,as long as they are in separate pipes all is good according to him. I've 20m to dig so I'm happy I don't have to do two trenches. My question is about the waste pipe, do I need a 110mm waste pipe for what is essentially just going to be used for water and grain bits or can I get away with a normal 32 mm white pipe? I know the pipe is able for it, I just don't know if it's ok to use it underground I was going to connect it to the existing waste pipe that is on the house, I've a manhole just outside the backdoor that o was hoping to get the pipe to Link to comment Share on other sites More sharing options...
Cpd Posted August 16, 2020 Share Posted August 16, 2020 I personally would use 110mm as if you need to clean it / unblock it for any reason it will be much easier. Link to comment Share on other sites More sharing options...
joe90 Posted August 16, 2020 Share Posted August 16, 2020 I certainly would not use 32mm, 50mm minimum but 110mm is better. Link to comment Share on other sites More sharing options...
PeterW Posted August 16, 2020 Share Posted August 16, 2020 As others say - 110mm ideally but minimum 50mm. Link to comment Share on other sites More sharing options...
Nickfromwales Posted August 16, 2020 Share Posted August 16, 2020 Can you get a fall with 110mm? If so it's a no-brainer to install 110mm. 50mm will need supporting right along its length to stop dead spots where crud will accumulate ( especially with what you'll be sending down it ) so over 20m I'd not risk it unless you lay the 50mm on pads of 6:1 sand and cement every 300-400mm and then backfill around it and over it with dust / fines with at least 200mm of coverage as the pipe is brittle compared to UG soil pipe. If no fall, drop 25mm MDPE in and pump it away with a saniflo / similar waste water pump. Link to comment Share on other sites More sharing options...
Nickfromwales Posted August 16, 2020 Share Posted August 16, 2020 Either way, use push fit not solvent weld ! Link to comment Share on other sites More sharing options...
Conor Posted August 17, 2020 Share Posted August 17, 2020 110 will be easier to install (more rigid, easier to set levels) and with brewing waste it's inevitable that you'll get a build up of sugary waste that will quickly block a 32 or 40mm pipe.

Onoff Posted August 17, 2020 Share Posted August 17, 2020 Look to compost the brewing waste if you can. Not sure what you're brewing but if grain based then you need to keep the compost bin well aerated as grain waste is nitrogen rich. Link to comment Share on other sites More sharing options...
oddjob Posted August 17, 2020 Author Share Posted August 17, 2020 thanks for the input lads, I hear ya loud and clear, 110mm pipe it is so. back when i was on the sites some 20 years back an inch fall per yard was recommended, does that still hold true or is there an new take on whats needed?

PeterW Posted August 17, 2020 Share Posted August 17, 2020 Inch per yard is 1:36 which is fine Link to comment Share on other sites More sharing options...

oddjob Posted September 7, 2020 Author Share Posted September 7, 2020 Cheers lad, pretty chuffed with it having never done any ground work before. Yeah, pick and spade job, great fun was had. There is a trench filling party on Friday, bring a friend ? Link to comment Share on other sites More sharing options...

Cpd Posted September 8, 2020 Share Posted September 8, 2020 I Have just done something similar and put A small inspection chamber in one pipe run and a Potential rodding point in another, I am far from an expert but liked the idea that should something go wrong I had the ability to see it and be able to sort it out without having to dig it up. I assume you can rod from the brew shed if required. Link to comment Share on other sites More sharing options...
oddjob Posted September 8, 2020 Author Share Posted September 8, 2020 never thought of that. I do have a rod and am somewhat confident that I'd get it in from the shed drain if i had to. Thanks for the input though Link to comment Share on other sites More sharing options...
Ferdinand Posted September 8, 2020 Share Posted September 8, 2020 Presumably having a 110m pipe might facilitate providing somewhere to pee should you drink it all in the shed... Link to comment Share on other sites More sharing options...

A pick to the shin is painful enough Link to comment Share on other sites More sharing options...
