This is about heads blocking on the outlet side.
Lots will be familiar with scale forming on the inside of the outlet pipe and eventually blocking it. Remedy suggestions often include vinegar application etc but normally you end up taking out the pipe to clean with a dammed good thrashing (!) on the dock or replacing the pipe.
So, on our liveonnit boat, I was used to doing that wonderful job about every 8 or 9 months. Lavac.
In S Europe, there is widely available, at less than a quid a litre, a product 'Agua Fuerte', literally Spanish for strong water. Its about a 25% solution of hydrochloric acid.
I have been using this stuff in on average 2 weekly doses for 3 years.
Hey presto, no blocking! Also absolutely no observably effect on pump, head unit, pipes or hull valve.
Not sure how it would fit with UK attitudes, but can recommend it. Also widely used in boatyards after lift out to clean props and shaft, simply dissolves barnacles etc.
Take sensible precautions and flush a lot!
Have now got a second yacht, with Jabsco. Will chekkit out.
