Looking for something else, I spotted photos I took in February of our old accululator. I say old... it's still in place... I don't know how old it is, but as we had a new water pump installed in February, I want a new accumulator too. I don't know how old this one is, what make/model - how many litres - 5? Photos show old water pump in place. It's all a bit grotty down there, but, yes, I will clean it all up, probably this Christmas. Any idea how to get that old grey cylinder off? Does it just twist off on a thread? Will I need plumbers pvc tape? Will a new accumulator have a standard thread? What's that silver plate for, under the cylinder? The marina owner suggested an Aquafax ... this is what seems to be it: www.aquafax.co.uk/products/accumulator-tank-5-litres-3-4-bsp-male-acs05-9-40303 Jabsco also seem to do one: Are there any other/better makes I should consider? Does the old one we have look like 5 litres? What about something like this? Looks nicer than those ugly 'gas bottles'.

The bigger it is, the longer the taps will work between pumps.

Yes the bigger it is the longer between pump runs. All they are is a cylinder with a rubber diaphram dividing the internal space, when the pump operates the water fills the void on it's side till the diaphram gives enough to reach cut off pressure. When you turn on the tap the diaphram forces the water out and then the pump kicks in repeat and repeat. So no need for fancy names on the box, Screfix will do or any plumbers merchants. Phil

Phil However there is an important difference between such things designed eg for central heating (with inhibitor) or for drinking water.

It has to be marked as suitable for potable water or it will rust through very quickly.

If it's working, why replace it?

If it's working, why replace it? As said above - I don't know how old it is, and I'd like a new one before this old thing breaks. The new one should go for 10 years so I won't have to fiddle around down there again... although, now I think of it, the Whale Gulper is close by (for the shower) and should I be digging that out and cleaning that, or a filter or something? I like to change things before they *pop* - like the bulbs in our car - get them done in October so there's less chance of them failing during the dark and cold winter.

As I said in another post; O.C.D. Accumulators/Expansion vessels work in different ways. A potable vessel has a bladder inside, which is held in place by the silver plate. Water doe not come into contact with the steel case. A heating vessel has an internal diaphragm that is sandwiched by the two halves of the cylinder. They both connect with a 3/4bsp male thread and they are parallel threads. They will screw all the way down into a female fitting which also needs to be parallel rather than taper. A sealing washer between the vessel connector and the pipework connector will seal it, but PTFE (plumbers) tape will reinforce the seal. A spare set of bulbs can be carried (a legal requirement in France) to accomodate any failures. When you change yours in October do you keep the old ones for your Christmas Tree?

As I said in another post; O.C.D. Have made a note to look that up. There might be some of that. I shall try to think of examples of me being guilty of that. But I think it's just me wanting to get on with life, and making sure I can because the annoying little things are kept well and firmly nailed down in the background.

I keep the old ones, yes - if they're still looking OK - although, much better is to have new ones as spares. They're not expensive. A 5W glass-based bulb will be much darker than a new one, after being 'on' for a year.
