Rinnai HWS & Pressure Tank

Would this work with the pressure tank?
Controller comes with a fully adjustable cut in (start) pressure of between 0.5-6.0 bar and a cut out (stop) pressure of between…

By 'closed discharge' I assume that means a pressure tank!
I give up. All too hard. Will have to look at a Grundfos like most of the neighbours have…

Oh, so if the pressure tank is 30 psi are you saying I only need a cut-out a few psi above that?

Thanks for the info and your time with this. A new electronic pressure controller seems the easiest solution, if I can find something suitable. The D switch looks a…

Rinnai HWS & Pressure Tank

So basically a pump with one of these type fixed controllers will never work with a pressure tank. Too much run on.
What must others use with a pressure tank?…

Ok, the penny has dropped. The controller is only adjustable for the cut-in. 1.5 - 3.5 bar.
The cut-out is fixed at 8 bar (around 116psi),…

If I pump the pessure tank up to say 52psi (have to experiment) to satisfy the pump it'll then only deliver maybe 5L before the pump kicks in. But…

I meant the Grundfos (without a larger pressure tank inline) would come on and off every time a tap is opened. Well, not everytime if it has its own 8L…

Yes there's not enough adjustment in the pump to bring it down to suit the pressure tank.
The Rinnai are a lot better now with low flow. I can turn…

Thanks for the reply. The pressure tank was originally installed to reduce pump startups so less wear, and supposedly less power. But, I have since tested the pump…

Rinnai HWS & Pressure Tank

On tank water only and we're having troubles with our Rinnai 20 instant HWS. The Rinnai is fed by the pump via a 60L 'Pressure Wave' pressure tank. …

Toilet waste too close to wall. Help!

Thank you for that. This one from Marbletrend has a adjustable S trap 70-170mm so would be ideal. Problem solved. :D

Pan photos to show the problem.

Will one of these work with the pan?

Although, I'm concerned the pan won't sit flush on the floor.

The toilet waste pipe in our slab should've been positioned at 150mm centre setout from the plaster wall but has ended up only 115mm - 35mm short!

The toilet we bought…

Ripped off by our concreter. Please help.

Thanks, good point. I will keep that up my sleeve.
Thanks for the advice. Certainly has been a wake up call.

Hi everyone, we are owner building in regional Qld and putting up a kit home and shed. The concreter who did the shed slab held us to ransom half way…
