Water flow problem.

[suts89]

Okay got a strange one here.

Due to an up and coming extension build i have had to make alterations to both my central heating system (removing 3 rads) and water pipes.

The heating went well apart from a bad back from lots of crawling below the ground floor

I thought the re-routing of the water pipes had gone well untill i noticed a change in the water delivery from the kitchen tap, the water appears to be coming from the tap with less pressure and the flow is not as smooth (Spluters) as it was.

Its going to be difficult to explain in words what was and what is but here goes.

PREVIOUSLY.
The mains water enters the house below the kitchen sink (Stop cock) from there it went to both the kitchen sink and als T,d off to the first floor where it picked up two bathrooms before coming back down to the ground floor and into the combi boiler.

NOW
The mains water enters the house below the kitchen sink (Stop cock) it picks up the kitchen sink and now T,s off too the combi boiler. Just below the boiler the cold also T,s off up to the first floor where it picks up the two first floor bathrooms.

Do you think what i have done has affected the water delivery at the kitchen taps and if so how can i fix it?? I,m thinking i may need a check valve somewhere in the circuit but am not sure??

Thanks in advance for any help.

Cheers

I would say the stopcock isint open properly or you have managed to get dirt and/or ptfe tape into the pipes.

Thanks for that, checked the stop cock and confirmed it is fully open.

I removed the end from the tap (Filter assembly dont know the correct name) and found a little bit of dirt. However the symptoms still persist.

Any feed back much appreciated

Cheers

have you used copper or plastic ? the only time I have had the same problem you have is when a customer had used copper fittings, and on one tee he hadnt realised it had no stops inside, took a while to figure out why there was no flow from one of the taps.

Piccaso,

Thanks again, i have used John Guest Speedfit plastic pipe and fittings.

Dont know if it has any relevance but the kitchen tap is a mixer type and the symptom is apparent when running both the hot and the cold.

as the hot is running off a combi boiler the pressure is reasonably balanced so you dont need check valves, you normally get a bit of air from the taps when you first switch them on but it should clear within a minute, try running all the taps in the house to clear any air trapped in the pipes.

Picasso,

problem solved, you wouldnt belive it! Well you would as you were already close to the mark with your first response.

I again went back to the filter assembly on the end of the tap. Closer inspection found the first stage of the filer actuall had a split in it and tiny pieces of dirt had found there way in and were clogging the next stage of the filter

Thanks for your valued assistance.
