Hi I need to replace the waste pipe from my tiolet to the waste tank. Not really a hard job i know but i can't find a turn off valve to it. What i want to know is this: The pipe from the tiolet to the tank, when removed from the loo end, was holding water If i take off the end from the tank to replace it, is it going to pour water out of the holding tank if it has no shut off valve or just what the pipe is holding? Any thoughts would be good. Thanks Chris
Does the waste pipe join the Holding tank at the top or the bottom of the tank?
If it is at the top (which I think is more likely ) then you would only spill the contents of the pipe. Recommend you flush thru with fresh water ( or river water) before removal. Better still if it is an ITT toilet (the one with the handle operatered pump) disconnect the flush water intake pipe and pump air thru the system and this should clear most of the contents.
If for any reason it joins the tank at the bottom then you are going to lose the contents of your holding tank into your bilges (or worse). In this case I recommend you have your holding tank flushed and pumped several times before attempting this operation. Most good boatyards will do this for you if asked. Infact ours does it as routine.
Whatever happens from one who has spend more than a few unhappy hours overhauling toilet systems recently.
Hi Rod Thanks for the reply. It seemed such a simple job!! The tiolet is an RM69 and it was meant to be undo 4 screws and 2 jubilee clips and put it back together job done in half an hour!! The pipe from the loo to the holding tank is located at the top so fingers crossed no too much poo smell in the boat!! The old pipe is rock hard and has now deformed where the old jubilee clip sat around the top so it will not make a seal now and when you pump the loo it throws water up around the joint and in to the shower tray,nice for washing your feet!! The real pig will be threading the new pipe through and up to the loo. Any easy way of doing that? Tie some string on it and pull it through? It's my first boat so not really sure how the loo works yet or much else really. Got an RYA inland waterways course a week Wednesday so things should be clearer then. I will have a go at the pipe change as it is pretty straight forward and with all these BSS test works being done getting it booked in anywhere is a real nightmare. Regards Chris
Hi Rod I had thought of the duck tape method so i will try both and see which works first! The good thing is that the holding tank is easily got to and the boat was for sale in a brokerage and stored all winter so it has been flushed and pumped out before we bought it I just need to get some more pipe and have a go. I was told today that you should heat the pipe up with a heat gun before i fit it to the loo and holding tank to make it softer so i get a good seal,is that a good idea or just use some good old washing up liquid to slip it on with a good push? Chris
Hi Rod I think the best way for me to go is leave it rigid until i thread it through and then boil the kettle and dip each end in the water as i connect them and that should give me 2 soft ends to work with and hopefully make a good seal once it cools off. Chris
