New bathroom plumbing help please

[joni os]

Turn down temperature of hot water at combi until you get 43 C at sink with just hot tap.
If shower then functions OK, cold supply problem confirmed.

I have a new combi boiler and the mixer is this one. The issue must be with the mixer valve as it feeds the shower and bath which are the only places where I have a problem.

Thanks joni... I will definitely test that out!

Following your link you have both check valves and filters. Remove, flush pipework, clean filters and reassemble.

I was just watching a YouTube video out troubleshooting shower valves. Looks like that's what I need to do, thanks. Should this happen on a new fitting or did I miss a step out when installing?

Sounds like I might not have to take off my new tiling...yay!

 

[joni os]

You missed the bit about taking out the check valves and flushing the pipework leading to the valve.

 

[Taryn Hauritz]

Yes!! Lesson learned. Hopefully I can post good news tomorrow that I've resolved the issue - thanks for all the help!!

That valve is just for a shower with two outlets , a fixed head and a sliding rail, did you say it feeds the bath or am I picking u up wrong , ???

 

[kris]

It's not designed to feed a bath just , fixed, rail or jets ,

 

[Taryn Hauritz]

Yes, it has a temperature control and two outlets. One for the shower head and one for the bath. I have two of these in my home...both working well. This is the first time I've installed myself though!

then youve answered your own question as to where the fault is

A weeks full of free advice and still scratching your head

If you read the specifications for the shower it's designed for two outlets to run simultainesly , either a shower fixed head , shower sliding rail or shower jets , it's not designed for a bath just a shower , the flow rates will probably take ages to fill,

 

[Taryn Hauritz]

So I have exactly the same shower valve mixer in my house in two bathrooms and have used for two years without a single problem. I get that I'm totally new to plumbing and will keep trying until I figure it out but even if the product is not designed for this purpose, there must be a way of making it work like the two in my house?

Anyway, I'll stop posting and try some of the good advice that has been posted previously.

I read that in thinking it gives you the option too run at the same time, pretty sure the top and bottom valves are just 1/4 turn stop valves? , agree like you say poor flow rate for bath filling,

Taryn is there any chance that you have piped up the hot to the cold on the valve?

 

[Taryn Hauritz]

No.

 

[AMW]

You say you have 2 installed already but are they not just supplying showers and if there is a bath are you sure they are not pipe separately which is why you don't have issues with the others??

 

[Taryn Hauritz]

Good point. I'll ask my friend who installed the first one - I'm seeing him tomorrow and see if he can shed some light in the issue. Thanks.

 

[Taryn Hauritz]

Actually, on further reflection I'm not sure how they'd be plumbed in separately as the temperature control works for both shower and bath filling!

 

[Staffy85]

No.

you sound confident, was the hot pipe actually the hot pipe though

 

[AMW]

Maybe a picture of the others and do the others have baths?

How does it fill the bath , is there a fixed outlet above the bath or a single tap ?

 

[hammers4spanner]

Just phone an expert!!!

 

[Taryn Hauritz]

Honestly, what's the point of having a forum if I'm just going to be told to get an expert in? I discovered I really enjoyed plumbing and as a beginner I thought this would be the place to get some helpful advice.

I have always said on my posts that I'm a beginner and honestly I'm really proud of the plumbing I have achieved (having never done ANY before). I talk to all of my friends about how cool plumbing is and they always laugh. But then, the consistent attitude on this forum of "you're obviously incompetent and need a professional" is really putting me off asking for advice. Perhaps I'll just go back to my local plumbers merchants....where they're nothing but helpful.

Sorry for the rant but as a plumbing enthusiast I'd really rather be encouraged to learn from my mistakes rather than give up at the first sign of a problem. If I had that attitude I would never have installed a kitchen, bathroom, flooring, walls and shelving in my new flat by myself.

If I mess up completely and have to call a professional in, then that's my choice, my expense and my responsibility.

Nothing worth doing was ever easy.
