Hi all,
Our accumulator membrane seems to have broken down, based on its leaking water after the pump runs.
I'm planning to replace it, just wanted to sanity check a couple of things before I do... apologies if any of the questions are a bit dim; I haven't done any maintenance on the water system til now.
Potable water. I've read elsewhere on this forum that accumulators are usually colour coded, where red is for heating and white is for potable water. Does that mean e.g. this model is for heating, despite being in the freshwater category? https://www.marinesuperstore.com/freshwater-system/water-tanks/jabsco-2l-accumulator-tank
It seems perfect otherwise, and I keep coming across ones that look just like it. Some of them are explicitly labelled as suitable for potable, but I'm not sure how much I trust that the descriptions are true.
Plumbing fittings. I've attached a photo of our old accumulator, which is plumbed in via hoses connecting to a t-junction. As far as I can tell, that t-junction can't be unscrewed from the current accumulator - despite other accumulators looking like they just have a threaded output. Do I just need to be more forceful? Some special spanner for the plastic bolt?
If I can't detach that t-junction, do I just need to get a new t-junction for the new accumulator, unfasten the current hoses' jubilee clips, then refasten them on to the new t-junction?
The narrowest part of that t-junction seems to be about 12mm. Does that mean a replacement should be 1/4in? (No idea about standard sizes.)
Thanks all, I'm hugely looking forward to fixing this and getting the bilge dry again...
