Re: [Amel Yacht Owners] Re: Electric Heads
Our backflow problem has been much better the last 2 years with some modifications, but still not ideal.toggle quoted messageShow quoted text
I bought the locking pump mechanism as an entire new unit. Not much more $ than a rebuild kit. There is a bayonet in the lock that puts downward pressure on the flapper valve. That helped somewhat.
I then bought an in line valve (also a Jabsco part) that I inserted in the hose about three inches after it exits the head on its way to the tank. That helped immensely for about a year, then the backflow ensued. I took the in line valve out and cleaned it, some sludge had accumulated. After putting it back, the head seems great again. Maybe there’s a trick in terms of flushing to prevent the sludge from accumulating.
Bottom line, it’s worth buying the locking pump and in line valve. I think you’ll be pleasantly surprised.
One more tip, Defender sells a much more flexible black water hose. Immensely easier to work with. It’s called Raritan Sani. I highly recommend it.
