Water pressure

If you increase the pressure too much you run the risk of blowing the joints apart.

Have you had a look at the pipe run? Yours wouldn’t be the first van built with kinks in the pipes or unnecessary loops and bends. It might pay to replumb it with a straighter run.

hi I would look at pipework to bathroom area as you say it ok at sink is it same on hot & cold?

Hi looked at the pipe work what I can see appears ok.

I realize working a submersible pump won't give you dynamice flow and I'm happy with it at the kitchen and I can work with the poor flow at the bathroom.

I was just wondering if pump with 17-19 flow would help.and not do damage.

I've done all the usual tracing of pipes and taking out filters.

Thanks for the posts but I have noticed this appears to be a common problem in older vans like mine and you shouldn't expect miracles.

Tks

I don’t agree about it being a problem in older vans. I’ve had vans 10 years older than yours that haven’t shown these issues.

I can’t advise about different pumps/flows I’m afraid as I know nothing about the fitments on your van. I can only again suggest getting underneath and replacing the pipes.

Good luck.

I'm wondering if, given the age of the van, it's simply a blockage somewhere - either due to algae or limescale.  If you can't take the pipework apart to clean it out, try running a solution of vinegar / bicarb through the system and leaving it to stand for 24 hrs (recommended, anyway as a means of descaling the boiler). Changing the showerhead may also be a quick way of removing a limescale blockage there.

As far as replacing pumps is concerned - when we took delivery of our van, I changed both pumps (internal and external) from Truma to Whale High Flows and the increase in pressure / flow rate was very noticeable - indeed our shower in the van is now almost as good as that at home.

Richardandros that sounds like a plan I'll get on the over the winter before the season starts again.

Like I say we don't use the shower and I do have water in the bathroom sink.

It maybe I am expecting too much from a small submersible pump.

Thanks to all.

Be intrigued no more, DD. It’s a well known solution - pardon the pun.

I remember my mum telling me and (just checked) Mrs C's grandma telling her it's an effective combination.

From memory from school it's all about the vinegar reacting with the baking soda to release carbon dioxide that makes it so effective?

There's plenty of stuff from a simple google search to get the right optimal ratio of one to the other.
