Is cold water flowing in to a tee like this ok?

 

[Newboy]

Yes.

Bear in mind that if the toilet is flushed whilst the shower is in use then there will be an effect on the cold flow rate.

 

[Riley26]

Yes its in the same on suite so shouldn't be an effect. I wondered if the tee would give a huge frictional resistance?

 

[Newboy]

not significant

 

[Riley26]

Yes.

Bear in mind that if the toilet is flushed whilst the shower is in use then there will be an effect on the cold flow rate.

Similar could be said if any cold supply is used whilst on is in the shower?

Tis no wonder we see some shyte installs out there....jeez

 

[Riley26]

Meaning?

It's less than ideal but in real terms it will make no difference to your install.

Preferably from supply through the long 'T' section with a riser on the centre to your first appliance to your second appliance with a pulled bend to the connection point. If possible/practical it's better if showers have a supply independent of other appliances.

(sometimes, for reasons best known to themselves, it's easier for people to make clever comments rather than provide practical help!)

I think the simple truth is that @Gaswizard doesn't know the answer so he resorts to abuse

I wouldn't worry he's obviously got a long way to go until he matches up to some of the guys on the forum. If you're lucky Agile may give us the definitive answer

Not exactly a "micro idealism situation" with regard to hydraulic loss through centre branch.

I'd also be interested to hear Agiles view on this.....
A learning curve is an understatement , every day is a school day when Agile posts on here , awesome....his knowledge is second to none...

So cold water flow in to a the centre branch of a tee is ok? I have seen it a few times under the kitchen sink were the incoming cold mains tees in to the house cold supply and kitchen sink tap feed.

So you recommend teeing off the hot and cold main supply's separately again to pick up a shower?

 

[Riley26]

Could teeing of separately almost make a dead leg in the hot pipework if the shower wasn't used for a long time
