Water pumps, flexible tanks and pipes advice

[gtmoore]

My Moody 29 has cold water hand pumps in the galley and heads. The rigid tanks now have Plastimo flexible tanks installed and it's all connected together using blue 12mm flexible pipe. It works OK but the pumps are a pain and tend to splash water around and it's hard to wash your hand and pump at the same time so I thought why not change it.

If I wanted to fit a pump and pressurise the system, I appreciate that I would need to change the taps but would the flexible tanks and piping be suitable? The whole system is unvented but would that trouble an electric diaphragm pump?

Thanks in advance for any advice.

A vent would be useful, but not essential with flexible tanks. The blue flexible will need a pressure rating of at least 4 bar, then it will also be ok. I would consider one of these newish pumps, that senses the amount of flow required and speeds up or slows down as required, it doesn't need an accumulator. I use the same pump, with a different system and find them quiet and effecient.

Can you tell me the make of pump you use for this Colin. There's loads on the market and I haven't seen a review of these types of pump in the magazines

Thanks

I'll have to get back to you, I can't remember the name, but they have been advertised in the yachting press, YM or PBO. They are a four diaphragm rotary pump.
