During our ownership of Mariadz we have had intermittent problems with the aft grey waste box which is fed from the stateroom heads (shower and sink) and also the galley sink. These have usually been as a result of a stuck float switch in the grey water box that gathers it all together before it is pumped away. The result of this has been a bilge full of water, or water stuck in the sink/shower. In the past we have cleaned the grey water box regularly (more precisely Stevie from Watercraft UK has cleaned this out for us and cleaned up the float switch). Basically the scum from the shower and the sink waste after washing up were causing us problems. During the last winter, we decided that we would look at this setup and also upgrade the Whale Gulper pump.
The upgrade was to use the toilet version of this pump. This is equivalent to the more powerful of the two grey water pumps but has a much wider pipe, let’s not linger on why that is required for a toilet pump…..
However, we have started to have problems with the pumping out of grey water again. This started in the last couple of weeks and we noticed that the pump was staying on for a long time and not pumping much water out. On investigation we found two of the non return valves, to sop the water going back into the pump and grey water box, supplied with the brand new pump by Whale had failed. One of them had turned inside and the other had a split in it. The first problem effectively reversed the non-return valve and so the pump was pushing against a valve trying to stop water going past. A service kit with replacement valves fixed this problem, I will follow up with Whale though. For the next few days, the pump seemed to work ok, well pretty much as it did before. Then, we noticed the pump performance deteriorating again. We had never previously had problems with the pump part of the grey water system so this was particularly frustrating.
Olly from Seapower had fitted the pump and diagnosed the initial problem as I eagerly watched on. So at least I now knew how to strip the pump down and check for problems – and although the pump has been moved to be more accessible it is still a horrible job of fiddling with pipes and pumps under the floor in the bilge in difficult to get to places. I did this adding a little extra water to our bilge as I went :(. The good news was that I couldn’t find a problem with the non return valves. I decided to swap the top of the Whale pump with our old, working, Whale pump to see if there was a problem with the pump caused by our valve problems previously. It did exactly the same. I put everything back together so I could show Olly, who was arriving imminently, what was happening. I retested…..now no water was going out, surely I couldn’t have reversed the valves accidentally when I put it back together? Thankfully I hadn’t. Olly and I worked together to try and diagnose the problem. Pump seemed fine, valves were fine (thankfully, that could have been quite embarrassing) but the outlet pipe seemed to be blocked. Now previously when we had the initial problem, Maria and I had put a hose through the this pipe to make sure it was clear but it now appear to be blocked. When we repeated the technique, the hose water was bouncing back off something. We went to the other end of the pipe at the through-hull to see if we could see the blockage. The pipe itself seemed fine. However the through-hull seemed to have a problem. There was a ninety degree bend immediately prior to the through-hull so we took this off and found that there was a huge blockage in this. I then set about clearing this out. I found two plastic screw covers
(the ones that disguise screws and make them look like the headlining or woodwork. These had jammed across the pipe together, which was little wider than these at the bend. This stopped all flow, especially as they had been packed in with hair and assorted other gunk. On cleaning this out we put the whole system back together and tested.
Previously, it has taken 30 seconds to clear the grey water box and at bad times up to two minutes. The pump started and I went up to the deck to check for the flow coming out. I peered over the side to see a dribble coming out, deflated I returned to the galley to talk through with Olly our next steps. He seemed happy and said that the pump had finished before I got there! In fact the pump had emptied the box in seven seconds! Even more amazing was that the pump emptied the box so fast that an emptying sink could not fill it quickly enough and so the pump ran and shut down and waited for more water before finishing the job.
So success. And Maria is happy to keep the boat because she can shower!
However, how could we stop these problems recurring. Some time ago we had bought a filter for the shower to stop too much hair getting through and this had worked well catching a lot of hair and needing cleaning regularly. I decided I wanted the same in the galley sinks.

gets you one of these stainless steel little puppies that fits the plug hole perfectly, has a very fine mesh that catches rice grains etc and looks like it is standard fit. So all those problems could have been averted for less than two pounds….
of course throws the compass off 😦 . we looked at the design of the standard steering column and were a little confused. Engine hours is important to keep an eye on but does this really need to be on the helm? We decided to move it down below. There were also some redundant switches. By carefully rearranging the steering column, with Olly from Seapower’s help, we were able to come up with a better design that also fitted in the chartplotter and the control panel for the Forward Facing Sonar. The radio bracket has been moved
away from the compass and the new remote control for the autopilot has also been mounted on the pedestal. Another change was removing the standard key to start and replacing with two buttons. At the end of the day the keys are all standard and so add no security but can handily (?) break off in the ignition at times. We just need to make sure that the ignition is switched off from the master control down below to avoid someone taking Mariadz away. Finally we added LED lights to light up the table when needed.

This time, we decided to bite the bullet and buy a couple for our bedroom. We would have to find a cheaper solution for the other cabins.
the mast or the boom we wanted to add some lighting.
This is taken from the batteries, so it isn’t long term, but can take care of short term peaks. What it does mean that you can run an aircon unit, maybe a couple of fires, hair straighteners, hair dryer, fancy a cup of tea – no problem. 🙂
We went with the e-xpert lite based on Olly’s recommendation. Over time, these type of monitors become less accurate though and need to be reset but they do provide useful data about what is happening right now such as amps in or out. However, anyone with an understanding of our approach to the refit will not be surprised that we would not be happy with a single way of measuring these things which could become inaccurate. There is another type of battery monitor which has a very complex algorithm within it and measures the battery itself to calculate a percentage of charge in the battery bank.
This system actually gets more accurate over time as the algorithm helps it to tune it’s settings to “learn” about the batteries it is monitoring. The combination of these two monitors gives us a powerful way of understanding our power use and state of charge. This will allow us to manage our power use much more effectively. We can monitor and adjust our power use and it will also help us to understand the effectiveness of our charging mechanisms: engine, shore power, generator and solar power. We will report on how well this works in practice in future posts.
The victron had some good features but the Studer seemed to have a better reputation for quality. The clincher for us was the global support network. They are both good but there are several times more dealers and repair centres for Victron, so in the unlikely eventuality that we had a problem, it would be easier to repair.

On the left hand side there were two chart plotters. The Raymarine was original fit and was linked to the similar unit in the cockpit. Around about 2010, AIS had been added and rather than upgrade the navigation a decision was taken to add an additional plotter to show the AIS information. Personally the thought of going below to check the AIS track of a large ship that may be on a collision course sounded like madness. Also with our plans to go round the world we didn’t expect the original navigation to last 25 years without trouble. So the decision was taken to upgrade the Raymarine navigation and remove the redundant setup. We considered other manufacturers but we have been comfortable with Raymarine equipment and so decided to stay loyal to the manufacturer, also thinking that it should be quite easy for us to understand how it worked since it would be an evolution from the equipment we were used to.
Of course an upgrade from that period meant that the existing radar set up would have to be replaced.
Forward Facing Sonar (FFS) so that we can see exactly what is in front of us and hopefully therefore avoid hitting it! Now on the East Coast, where we have very shallow water and mud, there is an unwritten rule that if you haven’t touched the mud you probably aren’t really trying ;). We are very careful these days having touched the bottom once in the Dufour but I am guessing that running into a reef will be no laughing matter so FFS it is. It looked like the Echopilot was the best fit for us and integrated with everything else.
We have combined that with a 7inch plotter which will show this view to Maria at the helm. I am led to believe that the purchase of this equipment was no reflection of a lack of trust in my ability to tell Maria if we are going too shallow but a niggling doubt remains… 🙂
