When a Plastic Bag Ruins Your Day
We started troubleshooting by cleaning the strainer and trying the trick we learned last month when it quit: turn the unit to heat mode (because heating the boat up extra warm is sure nice in July), triggering a valve that controls which way the coolant flows. Sometimes that valve can get stuck. Switching to heat and back to cool can correct that valve.That worked last month, but not this week.
Pat then thought it might be the water pump or the impeller in the pump since 3 out of the 4 units weren't working and we had just a minimal amount of raw water (sea water) running through the system. So he sent a picture of the pump to Jay at Yachtech who has helped us get quite a bit of work done on the boat and his response was:
|To get to these 2 units, it is best to be 5 year old sized|
|Some of the hoses that needed descaling|
|Black 'gunk' coming out was what remained of the growth that had been in the hoses|
|Showing the hose collapsing because it was too weak for the job|
Now those of you with boat AC systems have probably already thought about this, but we realized, since the pump worked and there was no growth in the system that the only part of the system left, was the thru hull. This is the opening under the boat where sea water is drawn in to cool the freon that then cools the AC. The thru hull must be blocked or clogged with growth.
After talking with other boat owners at the marina, many say they don't dive on their own boats here at Paradise Village, due to possibility of electricity in the water. I was also concerned with all swell motion of the boat against the dock. In our slip we drift away from the dock and back with quite a bit of force. I wouldn't want to come up between the dock and the boat at the wrong time.
So I texted Armando, who has a staff who cleans the hull of our boat. Of course now it's Saturday evening, we are hot, not pleased and somehow had skipped lunch during this process. We sat down to sulk just as Armando texted back, "I'll be there in 10 minutes". I can't say enough about the customer service down here. Armando shows up with one of his workers and a nice older gentleman who was probably his dad. Within 4 minutes, we pointed where the thru hull was, the diver went down and we suddenly had a huge flow of water coming out! The diver popped up with a plastic bag and some sticks in his hand.
|Not a spot I would want to be with all of the swells in the marina.|
|This little f*$%#r caused us days of work and stress|
Things we know:
1) Start with the simplest fix. We could have started with the thru hull, but hey we wouldn't have learned how to descale the AC system.
2) We should probably put a new AC pump on the list of things we should get. It turns out the strainer that comes with it, that is also deteriorating, was made in China and is discontinued, so we can't get parts for it any more. So a new strainer is also on the list.
