Bathroom Renovation Concerns, Help Please!

[Riley]

Will probably just be the new filler on the loo. Get installer back

 

[ShaunCorbs]

Pipes not clipped also prob

Ok thanks, due to issues we had with the installers little bit loath to reach out to them again but guess I might need to.

I think I will test it again tonight and pay more attention to when the 'thud' happens and then I can go back to them with as much info as possible.

To me it seems to flush and when the flush has finished it then has a small 'thud/vibration' occur. However I will try to work out if the thud/vibration occurs straight after flushing or if it only occurs when the toilet cistern has finished filling back up.

Thanks

If it is water hammer try closing your basin taps fast from fully open does it happen with these

Ok I'll try that when back home but as far as aware only happens on toilet flush.

Based on the above description I would expect a Part P certificate to be supplied, this will be a detailed list of the work carried out, parts supplied, location and a listing of the measurements taken during the testing. Especially important would be the position of the equipment to ensure that they complied with the zones listed in Part P. Also that the fan has a 2 pole isolator positioned outside zone 2. The shower isolator should also be accessible without hinderance. You should also check that the downlights are IP 65 etc etc. That's why the Part P cert is so important.
I've lost count of the number of times we have discovered hidden issues when doing the Part P checks. For example a property that had all the Earth wires in situ but the bonding was not connected to the property earthing pole. Or sockets where earth and neutral where reversed.

The vibration you mention is probably not water hammer as that is associated with the the cistern filling not water exiting the cistern. What it could be is a faulty air admittance valve which allows air into the waste to prevent air locking. It could be boxed in.

Yeah it seems difficult to determine what the problem could be as seems it could range from a lot of different areas. I'm going to try to work out exactly when it occurs but it definitely only appears to be when toilet is flushed and a few seconds after the flush.

 

[Old UKPF 85508]

Sorry just a further reply and something I will test when I get home, someone I know has said that a small 'thump' when using a half flush on new toilets is normal as the flush valve would be closing with the cistern still half full of water so a 'thump' is to be expected.

They asked me to check a full flush to see if the noise continues as a full flush would have the flush valve closing under its own weight.

Does this sound true to anyone? I'm going to try the full flush when I get home to see if it stops the problem but thought I would ask peoples opinions on here as well.

When you flush, turn the cistern stopcock off.
That way you will know whether it is a water supply problem - water hammer - or a cistern related problem.

Sometimes during flushing, particularly if you have a plastic 90 bend below the outlet of the toilet, that can make a noise as well.

It is true that sometimes with half flush the cisterns do make a noise, due to the weight of the water helping to close the valve, where as full flush the cistern is generally empty and the closing of the valve is not as abrupt.

See how you go

 

[Old UKPF 85508]

Ok thanks, I'm going to try the full flush and see if that has a thud after as maybe that really is all it is.

The thud isn't loud and there isn't any banging or rattling of pipes just something I haven't experienced before and due to issues I had with installers just makes me wary.

Thanks for the advice.

What area do you live in. Hopefully not rural with plastic pipes beneath the floor.
Mice and rats are buggers for chewing through plastic pipes and causing massive leaks.

 

[Old UKPF 85508]

No don't live rural.

Tried full flush and still makes a noise but my partner although can hear the flush doesn't feel any vibration and she thinks it just sounds like a normal toilet flush so think I will just monitor and see how things go.

 

[PlumbBobBob]

if you were to put your general location, there may be someone local to you who could come and have a look to put your mind at rest.

 

[Old UKPF 85508]

I live in North Kent, tried to listen harder when flushing and definitely seems to be from cistern so assuming it is the filler making the noise.

Hopefully will be ok as partner doesn't feel any vibrations so will keep an eye on it.

 

[Old UKPF 85508]

Just had a word with the supplier of the toilet and explained the problem, they are adamant it is normal and is the valve closing off in the cistern so hopefully all fine.

Any update since then?

I want to get my bathroom renovated in this way. How much it will cost me, I wonder?

 

[ShaunCorbs]

alot to get it done right

 

[PlumbBobBob]

I hope you don't get it done to US standards, electrics over the basins!
