Consumer unit is a 'contactum' and says RCCB on one label, also on paperwork it says RCD. Looked at contactum website - but it is being updated so not a lot of info there. Who are the main suppliers of these? What makes would you recommend ?

Consumer unit is 13 years old. If you can't get bigger than 100amps is it worth changing this ? Will they just add new lighting circuits onto existing ones :?

Hi, I hope you can help. I need to speak to builders about our extension and want to be able to ask the right questions. We had a new consumer unit installed 13 years ago ( label says not to exceed 100amps). The house is 1950s not been rewired and we will extend it with 2 new bedrooms, 2 new...

32mm now connected. Definitely more water coming out but rough bucket testing tonight maybe 16litres/min so not a flood given size of incoming. Plumber coming to test for real. Voucher for boiler hopefully arriving soon :)

Going for new supply pipe tomorrow a.m. as while there is a hole in the pavement there is an easy one off opportunity to link in direct to the external stopcock. ( There is a big tree on our boundary whcih would make it very difficult once the hole in the pavement is closed up). Then we shall...

Stopcock replaced and flow measured at 18/20 litres minute and 2.5 bar pressure. Water technician's opinion was we need to put in a 32mm pipe to make a 'megaflow or other' type system to work, and even a vented system would work better with a better flow rate than the 13litres/min got now. With...

Water company are coming again to fix our street stopcock which is broken and then measure pressure/flow there to see if any benefit from replacing our bit of the outside supply pipe that runs in garden. Only able to measure internally on first visit. We are linked via a communication pipe to...

Yes I think you are right ! But 'megaflow' systems have street cred /big marketing budget and I am trying to work out why they are so appealing but actually aren't always the right choice.

Agreed you need the correct flow and pressure - but if you are in a not great areas for water then the solution is not an unvented system. It is only by upgrading pipework/ getting an accumulator /Dualflow etc add ons to the pressurised unvented system that the thing works. Whole areas should...

If lots of money could buy pressure and flow from the mains then cost is not a problem. My point is that these systems seem so dependant on mains flow and pressure ( ie variables outside your own control) that they are the wrong solution for most people. ie mains pressure at kitchen stopcock 2...

Yes I think their pressure and flow will be similar - about 100ft away on same main - and they may not all shower at the same time and use the kitchen simultaneously so it may not matter, but I will investigate ! But my point is why go to all the expense of these unvented systems and then...

Just spoken to Megaflow helpline technician and he says need 1.5 bar working pressure and 20l/ min for effective use. If haven't got that then to help with pressure and flow can look at getting a cold water storage tank ! ( but the aim is to get rid of it!), and a grundfos home booster system...

But upgrading pipework won't necessarily improve much if the water main is at 2 bar and 18l/minute. So are these high pressure systems really able to work at lower flow rates ? Or why aren't there more unhappy megaflow ( and other) customers etc. Many thanks

Yes, I am trying to understand why megaflow type systems are so popular when in some areas water flow and pressure are know to be ''poor'' - ie less than 20litres/ 1 bar. So a professional company could not recommend them completely as water flow/pressure rates are outside manufacturers...

Yes would really like this apparently simple (tho expensive solution) ie we can pay for new pipe in our garden but concern is the flow rate is not 20 litres/ minute, especially in early morning 8amish when everyone else is bathing, in summers when water is scarce etc. So we could go to all...
