- This week we head back down to Hooker Pumps where we purchased our sea water circulation pump for some new gear and a big addition to the system! Then we head back to the boat for a new manifold and a pile of pipe and parts to assemble.

That is the best! To make a secondary system. Awesome!
Peek-a-boo, are you guys taking a well deserved holiday???
There's a head on the head!
I don’t want to be that guy, but the reason most folks don’t use 7500gph pumps for inflow is that if a fitting fails in the bilge you will sink your boat in minutes. You’ve now seen that sch 40 pvc snaps under stress, and that pump will outrun any bilge pump other than another hooker. At a minimum, you really need to consider a way to automatically shutoff the high flow pump with a high water switch in both hulls since your water routing will be in both hulls.
I was here to say this. This manifold should be made from bronze. I believe ABC requires these things to resist a 400 or 500# side load. I like the concept otherwise. This pvc looks like drain waste lines for residential house; they are built cheap and just strong enough for that applicaiton. These fittings, bends, etc. are really easy to calc. head loss. Given the oversize pump, 1.5" should be way more than enough, but that could be verified with a few simple calculations.
I like the new plan, please make sure to use schedule 80 pvc on the new set up as schedule 40 does not last long eniugh. Note that the blue handle valves are in the value category, therefore cheap and not recommended for sea water, always go with the red handle valves.
I love how neat everything lines up, but please cut the tails off the zip ties. lol. ❤
14:04 I’d use schedule 80 fittings for this. The regular household pvc may break under any lateral pressure, even continuous vibration.
That's a LOT of connections and having had one snap off already doesn't bode well for the current setup I fear!
Awesome
He says "I'm under the owners head" while in the video the head is on the owners head (like a hat). LOL
I like the idea of having backups to the backups
I understand the sweeping aspect of the plumbing drain fittings. But, as a master plumber I would question the pressure that the pump puts out and the DWV fittings may not hold up against the pressure in event of the worst case scenario as a crash pump. Pressure fittings have a deeper socket for gluing. They are designed for high psi. I guess that’s something to consider.
If you can snap off a fitting, you better make sure that fitting is above the waterline once installed, or you may be using your crash pump sooner than later. It looks like it should be, but just checking :)
Considering the risks with schedule 40 and the schedule 40 valves, using a Stainless Steel hydronic manifold and S.S valves which are actually fairly reasonable in cost would be the better choice for safety and long term.
I come from a water treatment back round , and I think your right on with the thought process. Always better to have and never use than take on water and go CRAP
“Crap” is much more polite than my vocabulary after it ting a container in the Bermuda Triangle LOL!
Looking at this I would say that you are of the right mind here. Having a way to chuck water overboard, with gusto, is a good idea. Having it built into the boat instead of relying on needing to first find it and then set it up where you need it makes total sense. It is always better to have and not need than to need and not have. Kim I know you don't like it when Ty drills new holes in your boat but this will be for safety. With this system you will have a better chance at keeping her floating if the worst does happen.
You have a fire extinguisher and hope you never need it. You have life raft and hope you never need it. You now have a crash pump and hope you never need it. It always makes sense to add the things that can save you even tough you hope to never use them. Redundancy is king.
I admire the ingenuity that you have. I am anxious to see how it works. Definitely one of my favourite youtube channels.
Definitely better to do it right. Really like that the pumps can be fully submersed and will still run. Yes, its extra work, but the peace of mind is priceless!
The problem with any tubing that requires barbed fittings is that every fitting restricts flow. Have you considered replacing the existing tubing with pex A? The walls are thinner so a larger pipe will have a similar OD.
Really like your "better safe than sorry" mindset, it will pay off if .... happens! Regrets wont save your family, this will! 👍
Thanks for all of your videos guys. I've been watching since the beginning and of love them all. I really found these last few with more of the technical specs and explaining what you're doing to be fascinating! Thanks again!
I'm lost, but still watching! Be well ❤
Great video, a quick question, what's the output pressure of the pumps? the DWV sanitary tees and Long sweeps are not really made for water pressure (like your manifold) just drains, have you thought about that? the boat is looking great, stay safe.
I was going to say the same thing. Looking great. Check on the DWV sanitary fittings.
Inspired, legend, you are one fire👍
It's Better to be safe than sorry. You think these things through and make it work. Many of us could not afford to do all the things you are doing but what we can afford to do we have learned the best way to do it from you.
Looking great team reminds me of my days building in ground swimming pools with your kind of manifold keep up the great work !!
I just recreated the manifold system on my boat but I had a hard time finding the fittings. I’m going to add a shut off valve to each AC as well but I haven’t found the correct size fitting yet. Debating on rebuilding the whole thing with larger PVC. Great video!!
Forgot to ask, where did you get all the PVC pipe fittings?
I purchased them online by make sure you watch the follow up videos on schedule 80
Ok yes, you are exactly right!! I recreated mine out of white PVC and it didn’t feel right. My previous manifold was made out of schedule 80. I am remaking it.
Getting water out of a boat asap is critical. You can never go ott on that🤙🏼🤙🏼🤙🏼🇦🇺
😄😄👍👍👍 ^You can never have too many back systems
I have always said better safe than sorry so if it’s not cost prohibiting do it.
Amazing project! And yes, it's better to have to much pumping capacity!
Every Hole in your boat hull is a point of potential failure that can sink your boat, so there is no such thing as too much redundancy.
You can never have too much emergency pump for when something unexpected happens. I think I would keep separate the overboard discharge from them. Takes time to get to any valves to isolate. Float switch/sensor and manual switch preferred. (Auto/Manual) selections.
Magical repair on the manifold Ty. Love what you're doing.
For that broken fitting they make a "drill powered saw" to remove the broken piece.
great deal and perfect tech for you clever company to support you
Thank you Ty...a hooker pump may be in my future...I was thinking inch and a half manifold but if you have the space 2 inch is much better. For those of you who are lost Ty is talking about the resistance of water flowing through a pipe. The larger the pipe and the fewer hard 90 degree turnd the lower the resistance for the water to flow. In addition. To the diameter of the pipe there is increasing resistance due to the length of the pipe. The resistance incurred is pretty much negligible in most boats.
Great video…belt and suspenders…always!
Interesting video, big fan of the sea chest approach. I like your tech-forward approach to solving problems: using the shaper to cut wood, the 3D printer, DC aircon, etc. Would be interested in your thoughts on marine textiles - it seems like sunbrella is what everyone uses for most outdoor marine applications and I have not really seen anyone try to use modern rip-stop Polyester fabrics despite them being significantly cheaper and arguably better suited for outdoor marine use on biminis, dodgers, or cushions?... maybe everyone uses sunbrella because it is really better or maybe it is one of those things where it is just the 'way it is done'. Anyway, just an idea for something you guys could look into, appreciate the interesting videos.
I use polyfab for cushions, seat backs etc. It’s not a question of durability for sail protection as much as it is a factor of weight. Love the ideas!
Any safety or redundancy items on a boat seem like a good idea, even to a non-sailor like me 😎
I LOVE the idea of being able to use it as a bilge pump.... UGH... I hate to throw a wrench.... can you switch it to bilge pump if that compartment is submerged...or too much to ask? OR... not needed because there is a LOT of bilge to fill before it would get to that point. REALLY REALLY love that you have thought of crash pumps!!! Your boat is leaps and bounds above others!
Better to have it and not need it than need it and not have it !
I wish you could have the crash portion able to be switched remotely (and also manually in the space), the last thing I would want to do is go diving for some valves in an emergency.
Thats what she said!
👍✅🏝
It would be much better if your manifold was a loop and the pump was feeding the manifold from a tee fitting. Doing that would even out pressure between all of the outlets.
It's not a bad idea having a crash pump on that boat especially since it has already been wrecked once. Back in the late 90s one of my friends purchased a 48' warlock world class high performance boat at auction that had sunk after ripping a large hole in the transom at 90mph. My friend fixed the boat and went through everything and first time out one of the engines slung a rod. He constantly had problems with that boat and I don't think he ever had a single good day out on that boat. One of mutual friends named the boat the BLB for bad luck boat. Eventually my friend sold the boat and took a $100,000 loss. After he sold the boat it had 3 different owners in a 3 year period. The last and final owner had a fire shortly after launching the boat. If curses exist that boat was definitely cursed.
Overthinking? YES! So in an emergency (PANIC MODE) you will have to go to the location, close and open valves to start pumping intrusion water over board? Won't you be busy running around with your hair on fire (wait....) you get it, preparing the dingy getting on lifejackets, grabbing emergency equipment, making sure everyone is accounted for and ready to abandon ship... WAIT, I have to go open/close valves! Just buy another crash pump like the one you are putting in the other hull. NOTHING for you to do in an emergency. Already could be pumping water before you would even know to close/open valves.
BUY ANOTHER CRASH PUMP. Leave the rest of your system to handle air conditioning etc. that you intended it for.
No idea what Ty is talking about, and I’d like to think I’m a reasonably handy person. A block diagram would be most useful.
Those fittings look like drain waste and vent I'm not sure their rated for pressure.
Just want to add a " that's what she said " to the very end of this video.
If you can make it fit the budget, too much is just enough, by my way of thinking. Keeping through hulls to a minimum is also a plus. I like how every Amel has only one.
