Just a quick couple of questions, I haven't seen or used any SF but I may be using it when I start moving and replacing various radiators and water points in my house.

The 4 port rail manifold, I'm guessing that any unused ports need to be sealed off? Am I right in thinking that the SF plugs (PL10/PL15/PL22) are the correct way to do this?

I also assume that you can connect more than one manifold together by the use of a 22mm pipe section?

Do they need to be attached to something to avoid any stress on the connections or will the support from every connection being attached to a wall be adequate?

Any other advice is of course always welcome, although I am fully aware of the importance of a clean cut and inserts with such a system

Thanks in advance,

Which manifold are you meaning, I've gone down this route for my new bathroom so I don't have to have access points all over the place for isolation valves.

If it's for water, make sure it's suitible for potable water - some were not when I last looked.

If you get the Speedfit ones, like I did, make sure the thread is good on the inlet. I had FIVE that were cut wrong and subsiquently stripped threads. They were from different shops too! SF QC was not aware of a problem when I called.

You can link the two manifolds together any way you want - once they are fixed to the walls, they are going nowhere.

I capped off unused ports with a small section of pipe with a cap on the end.

For those that are worried about flow rates and the taps - I timed it with and without the manifold and it made less than 1/2L of difference (25L without the manifold. I suspect that was because I couldn't open the taps quick enough - so it shouldn't affect flowrates, whcih surprised me.

Got to go to work, but here is mine.

It's not finished, but you get the idea.........I didn't WANT to use plastic really, but if you knew the shape/layout of the room, etc then you would totally understand why copper was not practical. Plastic fantastic really saved the day (lets say this bathroom is above FOUR different rooms and has 6 walls of stupid angles!!!!



If you notice in the pics too, I've also used those little clips to make sure the pipe doesn't come out/loose. The top of the manifold has little sliders that let you choose the name of the appliance (bath/shower/toilet/bidet/sink/etc) which is a nice touch

I was intending to use the style you have for the hot/cold water to give me a single source of isolation valves in the house. From the sounds of it you've already done some research and they are good for potable water? To be honest, it's not something I'd even considered but it will be used for drinking water.

The design I was more interested in is attached, I'm intending to use it for the central heating but I'm not likely to need all the outlets. When looking into it more, I found a SF plug which I assume is designed to be used instead of a length of pipe with a cap? Just I haven't found any definitive information to exactly what it's use is

Excellent advice about the threads, this is certainly something I'll be wary of when purchasing the manifolds!

Those plugs look like they will do the business. I only put the pipes with the caps in for added safety and I had them already. With the manifold I have, you can just turn the taps off. Nothing like belt and braces when it comes to water, I think.

I saw the manifold you show - I thought about it, but saw no potable water mention and even the guys in the shop couldn't tell me. I THINK it's suitible for just radiator and water systems, not potable.

The ones I shown ARE ok, it's in the product guides 'n everyfink.

Perfect, I can start putting together my order now! Thank you very much :)

I notice Langers2K hasn't been back in a while, but thought I'd update for everyone else who has this idea.

Connected up the toilet and sink on Thursday and found a bit of a problem with the manifold. If you try and adjust the flow using the manifold, there is a finite amount of adjustment to the flow before you induce serious water hammer.

Not a huge problem for me, but not expected (at least by me).
