The poor old diaphram 24 volt pump expired weezing gently as the pressure switch was never satisfied by it's performance.
So bounced off to buy a "computerised" pump that doesn't have a switch senses the demand and is silent, ha. (had one on the saily boat)
Unscrewed and condemmed the old pump to the shed (now filling with discarded broken bits of the boat) and plumbed in the new pump, removed the pressure canister and turned on for maximum smoke, wirrrrr wirrrrr, plenty of pressure then the hot water tank spat and spat. Hmmm new pressure relief valve fitted, mopped out the bilge (again) turn on pump, spat, spat, b£gger.
The pump says 2.1 bar, the pressure relief valve on the tank (C-Warm) is 2.5 bar, oh well off to the plumbers again for a pressure reducing valve and re-fitted the expansion tank after the new valve, wey hey all ok ....... until I turned on the hot water.... spat, spat b£gger.
So, reading the effin manual of course the expansion has to let off somewhere and I'd happily stopped it from returning back down the system, replumbed the pressure canister on the OUTPUT side of the hot water tank and at last no more spat.
Feeling pleased but stoopid that I'd not thought it through in the first place, just another simple job that took three times as long as it should have.
Next, the danfoss solenoid that looks as though it is the provider of fresh water from the tank for the washers. (But doesn't)
Already "testing the circuit" almost an enormous goof, With the 12V cooler box running all instruments radios chart plotters et all on I decided to switch on EVERYTHING just in case the blasted solenoid had been wired into some weird circuit.
From the breaker panel a click, hmm, no garmin network no VHF's no cd player, checked all the breakers, pulled apart the cupboard and went in with the volt-meter, sod all. Flicked the two 12 v breakers off and on and all was awake again which got me thinking, she's a 24V boat and there are 12V systems, no magic here then, the mysterious black box under the helm was too hot to touch (you've guessed it the 24-12v converter) so no more 12V cold box I fear without it's own 24-12V converter.
Just as daft, the aft deck spotlight fell apart so off to Halfords, sacrificed some bits from the old lamp housing new lense, clamp and buld, turn on for maximum lumination --- sod all - oh yes, 24 volt boat.... halfords 12 volt lamp.
BIG learning curve but getting there.
