Good stuff, Doug. Lift a board and have a look instead of trusting an electronic sensor - absolutely!

[@theessexhunter1305]

Doug, listening to your comment about if you block it you clean it reminded me of my time as a dive instructor in Egypt. The dive sites are marine parks so the paper is not flushed into the sea, it is put in a bin and then collected to be burnt. However with people spending a life time of putting the paper in the pan then the loos do get blocked from time to time. Included in the first day boat briefing is a reminder that the person who is in charge of cleaning the blocked loos is also the COOK lol This seemed to have a great effect on not putting paper down the pan...

Well that episode ended up in the crapper! Sorry I just had to say that. Great discussion on heads and how they operate. Another point to check as you do regular maintenance on your head is that anti-siphon valve to make sure it has not had anything get into it to reduce or prevent its operation. Thank you Doug and Betsy and the Seeker community. Everyone take care and stay well.

[@petemanley4221]

Entertaining and very useful video. Thank you :)

[@julestburt]

I'm buying a boat...but have lots to learn before I do. Apart from the sailing part, it's all the other systems on a boat I know little about. This was very very helpful...had no idea how those 'heads' work. Thx for sharing. Best video I've seen on this yet! Watching from North Vancouver, Canada!

[@SVSeeker]

Just go down to the marina in your area on the weekend and walk the docks. Make friends and offer help. I’ve been working all week on a friends boat. Started by fixing a leaky head. And been doing electric work the rest of the week. He has also done most of the navigation electronics on my boat. I think that is the best way to learn it and also the best way to find your boat. Beautiful country you have up there. I’ve sailed the San Juan Islands.

[@julestburt]

@@SVSeeker Great idea. Will do for sure. I have one good friend (very knowledgeable about this stuff too) who lives on his sailboat all year and lives around all those lovely Gulf Islands not too far from San Juan islands...delightful scenery I agree!

[@CaptRon817]

We used mineral oil and/or a small amount of vegetable oil as a lubricant. Just pour a little in and flush and that's it. Worked great.

[@KnightsWithoutATable]

Wadded up paper towels will plug many toilets, especially the newer "low-flow" toilets. I am impressed with how well this performed. Would have to see how it performed in service, but considering the design is so common, I expect that is is more than capable.

pmsl you brought back some memories of cleaning out jammed wc's on hire yachts , jeez some people just don't read the fucking manual and shove everything down the heads Damhikt ! Great explanation of boat heads and storage and capacities of tanks. All the best , Karl W

[@rlm98253]

One of your more lucid explanations.

[@TheBartmobile]

I know you are going for simple, but I highly recommend a macerator pump... no one wants to worry about their dump clogging up the hose. Put macerators on every commode. Also, sucking in raw water to use in the head will make everything smell WAY more than the poop itself. That raw water sitting in the hoses has bacteria in it, and boy does that water stink if it sits in those hoses for an extended period. I suggest having a separate fresh water system to feed all the heads. Put valves on all of those toilet “intakes” to suck in raw water if that fresh water supply ever runs low. Once the crew understands how the valves work, they will all appreciate the non-stinky fresh water option for flushing! I’d also get one big pump that can easily lift the waste at the dock side into the pump out station, or just throw a valve and that same pump can powerfully empty that same tank below the waterline when offshore.

[@stevenr8606]

@ Black Bart, so true. Salt water that sits does REALLY STINK!

[@Vikingwerk]

And get backup macerator pumps. I know several plumbers who swear the things are built to fail on a schedule.

[@manfredschmalbach9023]

It's a boat. Nothing, and that means NOTHING, comes in the bowl that wasn't gulped and digested before (besides wipepaper, we made that sole exception 'cause western landlubbers simply can not learn to put those in a bag ....) People signed that kinda manual on any vessel under my command on their first hour aboard, and we put up very steep fines for different sorts of failures caused by mistreating that rule. It worked well the moment we decided the whole crews had to pay those fines together, no matter usually only the female participants clogging the pumps on a regular basis with their bloody "sanitary products".

[@flamesandspoons]

Macerator is great on the ocean but illegal in most states. In Michigan they are illegal to even have on your boat.

[@Nevir202]

[@HankHill757]

Consider adding a bidet seat attachment (approximately $30) or handheld kitchen sprayer (bum gun) to each toilet instead of toilet paper. No worries about toilet paper clogging the system and save money from having to buy it. Bidets are the way to go!!

[@sjoerdbleeker7167]

Hi there! I also have a jabsco in my yacht, they work perfect except for the hinges on the seat. They break really easy. Maybe a nice cnc aluminium replacement project? Love the channel and the work you do! Best regards, Sjoerd Bleeker (naval engineer) - Holland

[@pawlarsen708]

Sewage odour can seep trough some plastic. Just a cation. I know in some cases special sewage pipes are needed. Thinking about your holding tank solution. Kind regards..

[@DustinCoffel]

Check out the seat mounted bidets. They are great and really reduce the toilet paper load. They also help on heigine when you are not showering everyday to conserve water. It would be a separate fresh water pressure line. You could probably tap the lav sink. We have one on our RV to help with the tank maintenance.

[@SVSeeker]

It’s all fun and good till the pump sucks in a jellyfish.

[@DustinCoffel]

Hahahaha...@@SVSeeker "fresh water"...

[@jessicav2031]

I like the idea of the valves. Have a valve on each hole below the waterline, and follow a checklist everytime you are going to leave your boat for an extended period of time. During normal use, leave them open and rely on the anti-siphon. Multiple layers of security :)

[@SVSeeker]

That is the layout.

[@KayZee1957]

We do what I think a lot of rec boaters do. We close all through hulls when we leave the boat. They stay open while we're aboard and can react to a bilge alarm.

[@retiredfederalie178]

It will be interesting to see how susceptible the barrels are to permeation. All the hoses and tanks ultimately end up with a smell. Also macerater pumps do have some lift capabilities but not much unless your buying high end ones. I have burned them out before. The good ones have rebuildable pump heads. Oh and what I have found that fills holding tanks faster that anything is those folks with table spoon sized bladders! And they use TP too! I like the simple pump toilets. Easiest to repair, unclog and replace if ya gotta. I have two electric ones now spent $375 on one for it’s pump (computerized nightmare!) Train the crew and stay simple.

[@thomasjeffersoncry]

Special hoses and tanks are required or the smell comes right through. I know bc I changed the outgoing toilet hose in my boat and didn't use the proper sanitation hose. Boat smelled like S***. Changed to the proper hose and all was good!

The extra valves seems like they might still be nice to have if you think theres a risk of the anti siphon ever malfunctioning.

[@repalmore]

"take it back" Sorry, most all the stores have signs up stating "no returns" and I asked someone that worked at a store I frequent and she said that no one had tried to return any TP. Yes, shitty of them to hoard. Of course I sorta bypassed that mostly with a bidet. Nice clean feeling EVERY time.

[@danielkeirsteadsr6939]

[@limerickman8512]

To check holding tanks and other things like it, just install cctv camera and a light to turn on to check if there any issue, attached to a CCTV to check for issues, if you are above on top and hear something you do not like and there is other activity that need your attention. Because it is part of CCTV you can have an app for that. This following system can even detect heat and motion detection, like the following product, which is probably not marine grade.

Rule is pump and dump as you go so the bowl stays empty of waste and full of water the jabsco can handle a lot just not all at once. I have a few stories from a life time of boating but best was on current boat my Sister in law a lovely lady used the head and it blocked not uncommon but trick on my system was usually to get up a bit of pressure by blocking the breather. anyway cork couldn't be found so I put my foot in plastic bag and stood on breather where it comes out on the deck and told her to just keep pumping she put her head through the hatch to tell me it was getting to hard just as I inadvertently lifted my foot she got the entire contents of the holding tank in the face in a microsecond.

I think I missed the episode where you went shopping for toilets! That Jabsco is absolutely the cheapest and the most in-efficient marine toilet known to man! It is really about $150 with your coupons etc. The next class of toilet is actually one of the best--The Raritan PH2--it is a hand pump also---but--it is light years ahead of the low priced spread---however---the price is over $400!! And I do recommend the vinegar--always buy at Costso---5 bucks for 2 gallons! I always give the females the"Talk"---about the care and feeding of the marine head. The boatyard dumpsters are always full of those Jabsco toilets, some of them real new! The Seeker is much better than this toilet!!??--------Mikey in Sequim

[@blondestrainger]

Pump style heads are great as poop will septic breakdown in the hoses . Get macerator style or short hoses but you will need at least 200 gallons storage if you are inshore and cant dump. Never rely on marinas daily. Six persons x four times a day x equals 24 gals per day and that is low as a real pooper uses much more. This is fifty years of Yacht and trawler building and Cruising with Family. Rethink capacities of tanks very closely . Ball valves every where on hand pump heads too. An open head below water or when you heel over will Yes Sink you ! Been there while racing sail Yachts and someone left the valve open , ME!

[@blondestrainger]

Oh that RV macerator doesnt work for shit above the tank even though it has a rubber impeller in it. Keep it below in the waste stream. Good luck and Good Pooping Mate !

[@sparkyprojects]

Personally, i would put a seacock in both lines, but place them so they can't 'normally' be operated, or lock them open, if you ever have to service the pipe (leak below waterline etc) you can shut them off to do the repair The alternative is to dive and insert a plug from the outside, assuming you're in warm enough water without sharks ;)

I have one of those Jabsco toilet's, the small bowl one (came new with my boat). Hate it. I'm a big guy like you. I'll get a large bowl, or house size bowl as their called later. After I use it. It takes a lot to flush out your poo. I bet about two gallons or more are used after a poo session. Half the time my poo just floats (pump pump pump..). My holding tank is about 25 gallons I think. A week is good for me before I pump it out. If you think at times, that you are going to be in port for any length of time, a large capacity holding tank would be great.

Sounds like installing valves on the intake and discharge make sense for easier repairs and emergency, even if you plumb in the anti-siphons so the valves don't have to be regulary operated.

[@nonplayercharacter6478]

Yes, I thought that too. Valves or vents? Why not both? Sounds only prudent. Doug would probably say that you could make every system redundant at the cost of actually making a boat, and he's probably right. Although, I think that holes through the hull would deserve redundancy protections, if anything does. I've probably seen too many submarine movies, it's always the valves that save them. :)

[@SVSeeker]

There is often a thru-hull fitting with a valve on it. That may be closed or if your getting just a little water it might have a strainer on the valve that is clogged or the line is clogged. Or the flap valve in the pump might need replacing. Or the seal around the pump piston might need replacing. Dig in! And welcome to boats.

[@Bill23799]

Tell your guests it could be a lot more difficult. You could have installed a Zero- Gravity Toilet. Those things are incredibly complicated. Zero-Gravity Toilet instructions 1. The toilet is of the standard zero-gravity type. Depending on requirements, System A and/or System B can be used, details of which are clearly marked in the toilet compartment. When operating System A, depress lever and a plastic dalkron eliminator will be dispensed through the slot immediately underneath. When you have fastened the adhesive lip, attach connection marked by the large "X" outlet hose. Twist the silver coloured ring one inch below the connection point until you feel it lock. 2. The toilet is now ready for use. The Sonovac cleanser is activated by the small switch on the lip. When securing, twist the ring back to its initial-condition, so that the two orange line meet. Disconnect. Place the dalkron eliminator in the vacuum receptacle to the rear. Activate by pressing the blue button. 3. The controls for System B are located on the opposite wall. The red release switch places the uroliminator into position; it can be adjusted manually up or down by pressing the blue manual release button. The opening is self adjusting. To secure after use, press the green button which simultaneously activates the evaporator and returns the uroliminator to its storage position. 4.You may leave the lavatory if the green exit light is on over the door. If the red light is illuminated, one of the lavatory facilities is not properly secured. Press the "Stewardess" call button on the right of the door. She will secure all facilities from her controll panel outside. When gren exit light goes on you may open the door and leave. Please close the door behind you. 5. To use the Sonoshower, first undress and place all your clothes in the clothes rack. Put on the velcro slippers located in the cabinet immediately below. Enter the shower. On the control panel to your upper right upon entering you will see a "Shower seal" button. Press to activate. A green light will then be illuminated immediately below. On the intensity knob select the desired setting. Now depress the Sonovac activation lever. Bathe normally. 6. The Sonovac will automatically go off after three minutes unless you activate the "Manual off" over-ride switch by flipping it up. When you are ready to leave, press the blue "Shower seal" release button. The door will open and you may leave. Please remove the velcro slippers and place them in their container. 7. If the red light above this panel is on, the toilet is in use. When the green light is illuminated you may enter. However, you must carefully follow all instructions when using the facilities duting coasting (Zero G) flight. Inside there are three facilities: (1) the Sonowasher, (2) the Sonoshower, (3) the toilet. All three are designed to be used under weightless conditions. Please observe the sequence of operations for each individual facility. 8. Two modes for Sonowashing your face and hands are available, the "moist-towel" mode and the "Sonovac" ultrasonic cleaner mode. You may select either mode by moving the appropriate lever to the "Activate" position. 9. If you choose the "moist-towel" mode, depress the indicated yellow button and withdraw item. When you have finished, discard the towel in the vacuum dispenser, holding the indicated lever in the "active" position until the green light goes on...showing that the rollers have passed the towel completely into the dispenser. If you desire an additional towel, press the yellow button and repeat the cycle. If you prefer the "Sonovac" ultrasonic cleaning mode, press the indicated blue button. When the twin panels open, pull forward by rings A & B. For cleaning the hands, use in this position. Set the timer to positions 10, 20, 30 or 40...indicative of the number of seconds required. The knob to the left, just below the blue light, has three settings, low, medium or high. For normal use, the medium setting is suggested. 10. After these settings have been made, you can activate the device by switching to the "ON" position the clearly marked red switch. If during the washing operation, you wish to change the settings, place the "manual off" over-ride switch in the "OFF" position. you may now make the change and repeat the cycle.

I'm worried about the sifon stoppers ur putting on if that the only line of defence to stop the toilet sinking you id still put valves in just in case if they stop working that way u r able to stop it quick... Also pulling wetter through the pipe puts negative pressure in the pipe same with a sifon but pushing it puts positive pressure in the pipe if the sifon stoppers work with a change of pressure of think that a different type would have to be used for the outlet and the inlet

They are reversed on the suction line. Not even sure they will be needed, but they are somewhere in my shop.
