Accumulator expense woes

[Gasmart1]

Hello to all. I have a very insistent customer who was keen to have an accumulator/pump installed and at the final hurdle done a complete u turn and opted to put a cwsc (ground level!!!) with a Stuart turner negative head single impeller pump to feed a megaflo and cold to the bathrooms.

I advised against this!

Guess what? It only doesn’t work!

Is anyone aware of a pump that would perform any better or do we all agree that an accumulator set up is the only way forward?

I would appreciate all professional opinions.

Let the debate begin...

I would appreciate all professional opinions.

If your first attempt didn't work, I think you should contact Heatrae-Sadia and ask for their recommendations, e.g.:

Technical advice

Personally, other things being equal, I prefer accumulators over pumps just because they're simple and have less to go wrong; both qualities I like more and more the older I get.

Why what happens in theory it should work

Now if it’s a demand problem fair enough

Thanks for the advice. I’m a one man band and yes the *** packet has definitely been utilised on this one!
The customer in question used to have a building firm and is full of it from time to time.
Greatwater was the original suggestion
as an accumulator/pump to be installed
but the customer seems to think that set up a bit too expensive.
They are back on mains for now but asking could a bigger pump do more?

I always cover myself with my professional guarantee...

Dissapointment

Thanks Craig. They’ll probably opt for that being “sneezed” in next!

And the dab looks good.
Has anyone installed?

No probs, I haven't installed one myself but I had quoted to fit one as a replacement for an earlier model, after speaking with grundfos these pumps are about as good as it gets. I would however speak to grundfos about the proposed system. Pressuring a megaflow might be too much strain on the pump motor.

What’s wrong with the existing pump ?
