$320 for tank and fittings , $340 for electric toilet and 5 hours labour x $30 per hour =$150

total cost = $810

I just would not be able to sleep with a tank full of my dung hanging over my bunk.

With a head and shower space like that one southace, you will be able to save water by showering with a friend.

The sea cock is below the water line under the sink it's just the original 1/12 outlet from the old jabsco hand pump loo.

Read topic title in poor light conditions. Thought it said FILLING a gravity holding tank. That's easy. S(h)it above the tank and let gravity do the work or s(h)it below the tank and pump the product uphill. Do not try and use a pointy stick for this purpose.

In my Noelex I simply used a 25 litre heavy duty (black) jerry can strapped next to the bowl. Had two of them so that when one was full could simply swap tanks over and carry the full one to a shore side toilet block and empty.
As Cisco said. Sleeping with a full bucket of **** hanging overhead is not sexy and it should not take long for Eau de latrine to permeate your cabin.

Well for your information Frant it's not a bucket it's actually a chemical resistant completely sealed holding tank far more Advanced than your jerry can procedure how sexy would it be pumping your poo into a jerry can and having to carry them ashore to a toilet block!

Since you all seem experts on where to fit holding tanks please tell where I should have fitted it , and where you have yours located?

South ace. Going to leave pulling your leg and barbs about buckets of **** overhead aside.
Please tell me that you have used correctly barbed elbow fittings and not PVC plumbing fittings for the elbows to your tank. You should have double hose clamps on all hose connections, particularly below waterline ie to your through hulls.
Please don't take offence, comments are serious.

One of the things I wished I had done when fitting the hoses to elbows etc, when I installed my toilet, was to heat the hose with a hot air gun to ensure the hose clamps were able to deform the hose into a nice seal. Not much heat, just enough to soften them up a bit. This was recommended to me by a shipwright and he said to do it with every hose even if it is easy to get on. I do this all the time now.

All the suction hose had to be heated with boiling hot water...... It is nearly impossible to get the dam hose off the fittings now unless I use a heat gun which I currently don't own. Why would I need double hose clamps ? Actually I don't really even need hose clamps!

I have had my survey and not due for another one until the insurance asks for one....actually they didn't even ask for one when I brought the boat!

i have had surveyors in the past suggest that I should have double hose clamps yet they don't condem your boat for that.

The only time i nearly lost a boat due to flooding was when the Sea cock snapped off well before the hose clamp failed!

If some how the new hose clamp below the waterline fails and the hose somehow heats to 80 degrees and slides of the hose barbs and water comes in through the closed seacock it will just go into my shower sump bilge where then it's pumped back out over the side and if that fails it will over flow into my next bilge which also gets pumped out over the side and if that fails it then goes into my next bilge which also gets pumped out over the side.

i don't take offence and I don't judge your comments seriously I just laugh and wonder if your name is really Frant = Rant

You did use PVC plumbing fittings didn't you south ace. If your boat is ever misfortunate enough to be flooded then you might have trouble with your insurance payout as the loss assessor will jump on the lack of double clamps and non regulation fittings even if that is not the cause of flooding..
however I am going to chuckle when the PVC fitting fails and your cabin is inundated with ****.
