I'm about to fit an Aqualisa digital pumped shower. It is my intention to use flexible inlet and outlet pipes and, if practical, to mount the complete assembly on some sort of rubber pads on a board in the loft directly above the shower. Hopefully I will not hear the pump due to the flow of...

Its not the decision of the store. Its the manufacturer's design that has to be complied with. Check the brochure to establish the height of a typical full height cupboard (they are the ones that normally go at the end of a work surface and go from the floor to the top of the wall units. The...

Bathstyle, my reading of the OP's post is that his bathroom floor extends (at the same height) into the hall. I believe its the same flooring; probably wood planking/laminate, which is now suffering the effects of water. He didn't mention anything about floor mounted fixtures, so I guess he is...

If your floor mounted furniture is removed, I would recommend you to completely remove the existing flooring and replace it with 25mm WBP plywood, with noggins centred every 200mm between the joists and screws every 200mm all over the ply. Overboarding the existing floor with 4mm plywood will...

If the the toilet is located nearby, you could connect the overflow pipe into the top of the toilet cistern. When either the toilet or cold water cistern overflows you will know about it and by removing the top of the toilet cistern you will then establish if it is the toilet cistern or the...

Lay a heavy duty damp proof polythene sheet on the soil and cover it with 50mm of sand to keep it down. I had it done to my house 18 years ago and its still very dry and doesn't smell at all. You need ventilation above it as well.

Doitall: I have seen a few systems without a roomstat. All the rads have TRVs except the towel rail in the bathroom which has 2 lockshield valves (1 for balance on the outlet, as standard, and the other one fully open to provide the route for the pumped flow when all the TRVs are shut.

Because, if the boiler and pump had a bypass circuit, all the rads would be controlled by their own TRVs and it would be a perfect system. The boiler and pump could then run (via the bypass) without damage if all the rads closed independently. A room stat would not be needed. Therefore, the...

I've always been told by plumbers and read in publications that if a boiler and pump are running, there has to be a circuit for the water to flow through. In the absence of a pressure relief bypass, if, during the "On" period (timed or manual) all the rads close due to the thermostats, the...

Namsag, With TRVs in a CH system it is usual to have the roomstat set fully open thus ensuring that the boiler and pump remain running and able to supply other rads with TRVs open. If the roomstat is set to a (lower) desired temperature the boiler and pump will will stop when the associated...

In your previous post you mentioned that the operating temperature range started at 35, which means that it must contain some hot water. So, I guess that a truly cold shower is not available, unless the knob can be set below 35. Best get Bro the Builder to look at it when he can.

Doitall you wrote: Yes, if any water was drawn off at the top of the cylinder. If the draw off point is lowered the pressure will increase at that point and so will flow, if the diameter of the outlet is constant. I know this because I have a powerful shower in a my bathroom which is great...

I think the guys here would want some more information from you. Who installed it? A qualified plumber or a DIYer? Presumably the shower is a mixer and the hot water comes from the new boiler. It sounds like the cold supply to the mixer is either insufficient (or non existent) or the hot...

As a fellow DIYer I think you have arrived at the right conclusion, assuming that an electric shower is not acceptable to 'er indoors.

The TRV is a non-electrical method of protecting the home user from excessively hot water. This suggests to me that the TRV would have originally been fitted to an old system using a simple back boiler in a coal fire (ie a totally non-electric boiler) to provide the hot water. If you now have...

Have you considered extending the platform across the whole floor (like a stage)? The current plan makes me think that water will splash onto the floor over the edge that is not protected by the screen. Water getting onto the floor will not have a drain to take it away. The person using the...

Hmm, not so. Megrahi was sentenced to life imprisonment, with a recommendation that he should serve at least 20 years before being eligible for parole. He was born in 1952 and sentenced in 2001. Add 20 years to the date of imprisonment and, if still alive, he could have been a free man at the...

Your tank, I guess, is not a regular domestic hot water cylinder, but just a tank for hot water. If so, I recommend you get a thermostat that fits on the outside wall of the tank, directly against the metal wall. These are available at most plumbers' suppliers. The thermostat will normally...

Thanks for the advice to drain down the cylinder first. It wouldn't be the first time that I forgot to do it (and probably not the last, either). I like the idea of extending the outlet tube into the tank to avoid the bubbles on the internal side of the wall. I am aware of the dip tube on...
