You are contradicting yourself,and having studied A -level geomorphology I will rely on my owm knowledge,but thanks anyway.

What happens if the water meets an impermeable layer and begins to accumulate,adding to saturation of soil etc causing "heave".I am no expert but I thought gravity exerted pull on water and the push you refer to is a consequence of atmospheric pressure.By the way its not my wall.

In was not around when wall was built,but would imagine the creation of weep holes at the time of building was a cheap simple measure.Surely even an undrained backfill will benefit froma weephole given water's propensity to pass though permeable layers.I do not think the back-wall was bowed but...

Builder has been dealing with a low retaining wall which bowed out.I believe the issue was that retaining wall was the problem as no weep holes were created.The builder has taken down the facing wall and built a replacement and has put in some weep-holes,even cementing in some small...

I have a defective shower which was fitted for a customer,where water is leaking internally,and am wondering what has caused this.Possible explanations are 1.failed PRD 2.blockage of outlet 3.failed internal seals I believe the problem is a result of misuse and the customer attempoted a repair...

Many thanks for this advice.I like the idea of staggering the battens,and will, allow for venting by having a 5mm gap between the floor and cladding.I also note the suggestion of using (panel) pins.I was hoping to cap with a dado rail or some narrow architrave.

I want to clad a wall to create something akin to a wainscot by cladding the wall to about 700mm in matchboard and topping off with a rail(dado or similar).i could use no nails and fix direct to wall or use battens which can be screwed to.The second option allows for future removal and the air...

I have rosemary tiles on my house and my mums,both located in the same district of town,in ex-council houses built in 50s.Is it possible tore-use?Assuming they are in acceptable condition is it economic to do so-I know larger tiles mean fewer battens needed and can nailed on more quickly ie...

i have fitted a new siphon but the toilet still overflows via stand pipe.Am I right in thinking I need to remove the stand pipe and replace with blanking plug(22mm).I assume the water will then escape through the siphon(Epson). Can anyone confirm this is right,and if not what alternative...

Thank you to both for the options suggested-would a digital be more suitable than an analogue version?

I have to repair my mums central heating.I believe the clock has failed as the diodes are not responding and neither CH nor DHW are responding,and the pump is not running.The boiler is a newish condensing heat only boiler with external valves sited near the DHW cylinder.Is it possible to buy a...

i had a Vaillant boiler installed earlier in the year and need some controls now that central heating is needed.My usual fitter is fully booked for several weeks ahead.Are there any plug-in controls that can be purchased alongside the 150 timer(or similar)?I am quite happy to pay extra for...

I think you have identified the purpose of a forum where ideas can be exchanged and expertise shared.

That is what I have done as on my Worcester RSF280 we relied on manual operation for simplicity-on when cold ,off when warm.

I have had a boiler fitted recently and have been advised to have some electronic controls,as manual operation can cause switches to wear prematurely.I am prepared to pay a little more if a control system is more simple to fit and operate.Any suggestions please?

They are on the gas safe register-she that she is bored with men who call her a plumberette.I will not wind her up by reiterating your kind comments.

Why-the plumber is doing me a favour,and I am trying to minimise her inconvenience.I am also a qualified plumber but do not engage in gas work.no doubt you are proficient in all aspects of the job,but I am happy to say I am still learning. I suppose your comment is to disguise your ignorance

i am having a Vaillant fitted tomorrow and need ti get an adaptor to join 20mm condensate pipe(solvent weld) into a sink waste,and then to outside drain. Can anyone please recommend the part I need -thanks in anticipation.

I have just bought a vaillant Ecotec28 and the fitter tells me the Glow Work CX 30 has the same internal parts.Have I spent too much by buying the Vaillant-to be honest I still feel it will be money well-spent. Any fitters noticed a similarity?
