Hey well that was my thinking as I know 12 is a big manifold. But as you know soon as mixer out the loop pulls all 12 pots to 5lpm. So it’s strong enough got to be. What u think?

hey nozzle, That’s the issue you see, when all are fully open they just sit at above 0.5lpm fully open no room to adjust. Even if I say did 5 at a time same issue. thanks

I have also been to a family's house that has a udf setup and noticed. one zone was calling with great flow 3 lpm but when I asked to up the other zone stats by the time 3 more come on there is hardly any flow for all 4 zones now. So what is the point in these flow meter pots. Its not like your...

Hi Can anyone please tell me these flow pots on my new 12 port manifold. When I get the first one to the flow I need the next one robs the one I just set and by the time I am at about number 5 flow pot there is no room to adjust the next pot and the others I just set are showing less than 0.5...

Hi Nozzel, Yes its been vented with a radiator in the loft at the highest point atm. Its also been flushed out dozen of time the way you describe. Its deffo not air. My thoughts are now the mixer when all complete with stat and holder could be crap still in the system from install still stopping...

Hi any thanks for your input. This would want to go where on the flow or return before the mixer? Thanks

Hey, yeah I think I will have too. I have noticed crap still in the system even tho it's been flushed out loads. When I clean it it seems to work better with stat in but still not great flow but better. I mean with a 12 port manifold is it possible to a just the flow to max if all are open? Max...

Hey. Yes the pump is a grundfos upm3 auto L. I have tried every setting/curve there is on it. For long periods too. I believe I just have it set on max now bec it is a 12 port manifold with approx 700m piping but still nothing. There is no Restrictions on the plastic drill holes in mixer...

Hi, Yes there is flow from the boiler that allows it to get to the mixer. Then the manifold pump will take over. I have had it out mate and mess about with it to see how it works but what ever I try if I do not remove the stat and holder from the mixer I get hardly no flow. When I remove tho...

Hi, I have it plumed in the correct way as attached. Pump flow correct also. I have bleed the system of all air. what do you mean regarding the venting? thanks

Don’t think my pics worked. Maybe now thanks

Haha thanks JohnD I have all my power ect sorted in ducting ready to be pulled out when needed. Thanks tho. Just need to know about the tiles on plaster and if ok to plaster backerboard to help me out with the way I am panning it. Thanks

Hi Nozzel. Thanks for your reply I have one only picture of the manifold and pump/ mixer before it was plumbed up and then close up of the mixer and pump now attached to the flow and return of the boiler. i hope this helps you give me some ideas as i am not stupid on this but am lost on this...

Hey. Thanks for the reply no we just have 2 en-suits. So as of right now we dont need main bathroom, Money can be spent else where, but I would like to 1st fix for new layout witch I have done when we go back to main bathroom. But for the time being plaster it all out and use as a office. Then...

I have attached a picture of my mixer connected to my manifold. I have highlighted the spring and red round stat if removed will allow the system to flow perfect. As shown on my manifold flow pots but as soon as I add these back in flow almost goes to 0 on the flow pots. Regardless of how many...

Hi all just doing my house up and we have ripped out the old bathroom. We are not looking to do this as yet as money is going on other things en suite ect. What I want to do is plaster the hole thing out and use it for the time being as a office. But knowing later on it will become a main...

Hi all just done a new Retro wet floor system in new house I am doing up. scratching my head with the flow of the system. From my finding and tests its something to do with the mixer not allowing the flow around the system. I found this out as I thought the pump was one not good enough or 2...

There only SE calculations not spec drawings it’s on permitted development. You don’t need calculations for timber joits i belive if there on a span tec sheet. Mine is for the steel but he has added joists for nothing for me on the calculations. I have moved the padstone in anyway so there now...

Thanks again woody, The steel is perpendicular to the padstone it’s on. No opening at the bottom just full wall all the way down. It’s a loft conversion. I could get 100mm on the padstone and just make the joists 5200mm looking at the span charts this is just ok for max veribale loads and...
