Proper video Adam. This is just the kind of info that new pond builders/keepers need to watch. You know your subject more than any other on youtube. A video on pipework, valves and return flow would be great sir. Congrats on over 20k also
Brilliant video pal, I’m in the process of accumulating everything I need for my build, I’ve got the same bottom drain and this has really helped with my thought process regarding design/layout etc. Keep it up matey 🤝
Hi Adam. A very interesting and informative video on Bottom Drains. I noticed that the bottom drain you had connected the air line by fitting a hose between the input and centre column within the bottom drain itself. Is that not a bit of a weak point as hoses tend to wear, go hard , loosen and come off. The bottom drain I used had grey pressure pipe going from the pressure pipe inlet to the centre column of the bottom drain. The centre column was fixed and the top screwed on to it. Using pressure pipe all the way to the centre column is surely safer. Looking forward to next weeks video.
I decided to retro fit a 1.5” 43m demountable union pipe fitting on the centre column of the bottom drain making it easier to detach if any problems with the air-line.
Great video mate helped me no end, I've got the exact same bottom drain running 4 inch to a ball valve purge and have fitted a 4 inch skimmer also. I'm still in build stage at the moment.
For once I was side tracked from a Adam Julyan video and clocked the snap on truck cart I’m ordering 1 of my snap on dealer 😂😂😂guess I’m rewatching video now 😂😂 great video Adam
😂 It is a great little storage box although I'm just using it as a filing cabinet not a tool box. Hope you enjoyed the rest of the video on your rewatch lol 🙂
Truck has been ordered . I won’t mention the price 😂. Yes I enjoyed the video I’m in the process of redoing my pond with a bottom drain this time so 👍. A sturgeon advice video would b good I would like to treat my pond for parasites . But can’t find any information I ask my pond store they try selling everything 💁
I have an idea for the fix of blanket weed getting caught in the drain. A divider that runs up the stem to the edge of the drain pan. Removing the ability for the blanket weed to hold on to the stem if the middle gets caught
Make sure your fish don't have a parasite and give it a little nip tighten remember it's plastic but it should tighten enough so its pretty well on there.
I've got a pond without a bottom drain, concrete base. Thinking of cutting out a section of concrete, undermining the walls and fitting a drain and then concreting in to original level, insulating and fibreglassing. It's part of an extension turning my 3 ft deep pump fed pond and making it nearly 6ft gravity.... Will be around 2500 gallons. Do you see any problem In doing the drain in this way?
Very informative adam mate 👍 I too didn't add a purge valve on my pond but i purge to the drum and rarely get anything come through, but i am running two pumps flat out so I'm guessing there isn't much chance foe anything settling.
It's not too bad with a drum filter as they usually have high flow rates but one of the things you can do occasionally which is what i do to purge my skimmer is close the drain valve let the pumps suck most of the water out of the drum and then open the valve so the water rushes through the system. Thanks for the comment 🙂
Hi Adam Enjoy ur vids esp purging a system! Doing the ground works to install my spindrifter nearly sorted. 2 Q,s do i place the db directly onto the ground thick clay or do i place it on a paving slab or a concrete base before i cement the pipework to get ready for concrete pond base fill? And what fall in the concrete floor to the bd do u recomnend? Max distance from pond wall to bd would be 6/7 foot. Appreciate any thoughts cheers
I usually put a bit of concrete under the drain its easier to get it level and stops it sliding about once you've done that put some around the pipe as well to support it so the concrete from mixer can't bend it. Make sure you put quite a bit of weight on the drain when concrete goes on or it will float away. It wants to be central with a good slope into the drain so everything naturally falls to the drain.
Hi Adam, great video. What's your opinion on retro fit bottom drains? Are they good at keeping the pond clean,are they better than a solids handling pump and filter set up? Thanks, I'm thinking of investing in one. Pond is already fibreglass so it would have to be retro fit one.
Hi Adam, I’ve had a pond built and a 4 inch air bottom drain from JBR plastics. This came with air dome, a grey collar between this and the main drain. The fitter has fitted it without the grey plate in between. He said it does not need it, my question is does it and what difference does it make in your opinion. Many thanks
Having a problem with my spindrifter bottom drain ,got a build up of air under the lid ,that is causing low water flow in to my filter .. any idea what problem is ??..
Had they placed a plastic 'hook' on the other side of the drain, one could bend rebar and pin it down to the bottom of the drain. And do pre-concrete mix to just affix it for the real pour.
Hi would you say its worth spending £160 on a spindrifter aerated BD against buying a basic bottom drain and attaching a separate air source to it ? . Pond build about to start, 3x3x1.5 Mtr block built but on a very tight budget . Your insight greatly appreciated.
adam first off thanks i learnt a lot of important stuff from this vid that i never new but whats you thought on gravity fed filters i dont like the thought of it i think i would prefer coming off the external pump but see a vid of someone saying if you have a 4inch bottom drain it would be better to have it gravity fed what do u think. btw your koi at the end of the vid looked beautiful what a nice selection of koi
Thanks 🙂. A gravity fed filter is the best way to go it keeps the pump away from the dirt so the pump doesn't have to handle solids which it would have to grind up into small pieces so your pump will live a lot longer with a filter before it. Because the pump isn't grinding the dirt into small pieces it make the filters job a lot easier. There are so many more advantages to gravity fed filters but I don't want to write a book in the comments 🙂 There are also so advantages to pump fed its easier and generally cheaper and if you don't have an above ground pond it means you don't have to bury your filter.
Hi Adam just a quick question at the 22 minutes point when you talk about fitting the liner flange do you recommend putting a bead of sealant between the underside of the liner and the bottom drain rim before screwing the flange down ?
Yes absolutely it wants a thin coat all around the rim to make sure it sticks really nice but not too much that it causes flange to sit unevenly I should have mentioned that thanks for pointing it out 🙂
Hi Adam, firstly great video and great pond you have there. I'll be fitting one of these in the next couple of days, never thought of a boot before, sounds like a good idea, what do you use to cover the jubilee clips. Oh and must be tight getting a screw driver in there. Hope you reply and stay safe.
It's a good idea to use a rubber boot to hold the drain lid in place it makes it a little easier if maintenance is required in the future. You don't need to cover the clips they will be fine although its best to tighten all rubber boots with and 8mm socket and wrench as a spanner will never get them tight enough and risk them coming off under pressure or time.
@@AdamJulyan Hi Adam, thanks that's great, just thought weed and leaves might get stuck easier on the clips if not covered. Anyway thanks for getting back and have a great summer.
This video has answered literally everything i needed to know about this bottom drain setup! Cheers mate 👍

Great video - what is the solution to stop the dome from unwinding
and coming off. Thanks

Where can you buy just the collum in the middle where the air goes in?

Another informative video mate..Learnt a lot from watching your vids, realise all my mistakes hahah
Good stuff, thanks!
Would a sweeping T be better than a 90 deg. T for the purge?

Yeah some way to actually anchor the drain its self down would be brilliant addition rather than relying on the pipework to hold it in place.

how do we ensure there is no leak when we dont use waterproofing?
Great video but for over 150 quid for the small one you can poke it!

Hi Adam. How far away are your bottom drains from your filter?
Hello sir, 4 inche bottom drain without air line how much? Thanks
Top Video Adam! Thank You
Glad you liked it! Thanks 🙂
Better way cleaner way best of bottom drain in stead of pump in pond nice pond you got mate
Yeah bottom drains do have their issues but its better overall than a pump in the pond. Thanks 🙂
Top Vid Adam your like Yoda of the Koi world :)
3:30 Giggity
IMHO the richdon koi drain is world's better. No internal pipe for blanket weed to get wrapped around and a bigger diffuser.
Ill have a look into that thanks for commenting 🙂
Could you not of used a power washer and jetted it out??
I also did that it wouldn't shift it at all even tried running the water backward out the drain with a powerful pump and it would move.
@@AdamJulyan wow you`d of thought jet would of just destroyed it wouldn't you.
I'm first! :-)
You cleaned up any conffusion about bottom drains very clear now
