are there any pre-requisites to going on the course, i.e. nvq level 3 or similar?

lol - nothing good to say about them?

Without wanting to open the flood-gates to another debate on the issue of Thermal Stores vs Unvented Cylinders, has anyone had any experience with the 'pandora' line of products of www.heatweb.com? More specifically, how do they fare on the following: a) Installation costs b) Maintenance...

For a horizontal run of soil pipe connected to 2 ensuite toilets + wastes for Shower/Sinks, where would you place the air admittance valve? i.e. at the furthest end or closer to the soil stack? Rough diagram: S ||==========TOILET==TOILET==VALVE? T || A || C || K || I understand...

Do you have any examples of these clips, say on screwfix.com? I'm wondering what they would attach to? (Joist?) Also, are soil pipe connectors ok to use in horizontal runs?

We are getting 2 ensuite bathrooms created, and the builder has had them plumbed using 15mm Hot/Cold Copper Pipes to the shower, and then feeds from there to the sink/toilet. I'm a bit concerned that the pipes have not been secured with clips and there is no lagging on any of the pipework (all...

When laying a soil pipe under floor boards for a run of about 5m (to outside wall), is it ok to use a soil pipe connector to join 2 pieces together? (rather than get one piece to cover the whole length). Also, what is the recommended method to stop the pipe sagging over the 5m length? Thanks

Hi Guys, We are getting our HW/CH system changed (as well as a new loft extension) and i'm wondering whether any of you would like to give us a quote. Work entailed as follows: - New boiler (kitche) - Unvented cylinder with break tank & pump (2nd floor) + connect to existing bathrooms -...

Hi Guys, You might have noticed that I seem to be asking a lot of questions regarding an unvented system for our property, even though I am not a qualified plumber/heating engineer. The problem i'm facing is that it's difficult to find heating engineers that a) actually know what they're...

Those look good - Thanks!

Can you recommend any makes/models of Break Tanks that can be used to store water and pump into an Unvented System (About 500 litres). Tank should have some sort of insulation as it will be placed in an area with no heating (but not open to elements). Is it possible to get tanks that keep the...

they'll actually be on separate floors. can you point me to the diagram online? thanks

Is it possible to use 2 Unvented Cylinders in an installation, which is heated by one main boiler? The thinking is that in a multiple bathroom house, each cylinder would supply 2 bathrooms (showers) (+ 1 kitchen). There would be a large cold storage tank located elsewhere, which with an inline...

Found this excellent guide to pipe bending. You'll need Adobe Acrobat, which i'm sure most pc's have installed already. Pipe Bending Tutorial

Victorian Townhouse. Distance from front to back of house is about 12m - internal partition walls are non load bearing.

I will check about the wallplate, but is there a recommended method of strenghtening joists to accomodate bathtubs?

I am looking to create an ensuite bathroom, which will be located in the 'middle' of the house next to a stud partition wall. What I mean is the location is in the middle of the long joist run from the front to the back of the house. The joists seem the most flexible at this point, and I suspect...

So the dualstream system is no different than using a normal expansion vessel? Will the water still be potable using a generic one?

The OSO Dualstream system sounds ideal for our requirements. Have any of you installed this system, or seen it working? I'd be interested to know how well it performs.

Chris, My apologies for my lack of knowledge. I was trying to do a bit of thinking for myself which clearly did not work! Anyway, I will measure my mains flow 'properly' this weekend and try to get hold of a pressure tester. Your first solution with the break tank sounds quite suitable as...
