Poor Cold Water Pressure in Bathtub Faucet: Exploring Solutions Without Damaging Tiles

Question

Hello Since I moved into a new flat in a bathtub faucet, cold water practically does not flow. Any other faucet (also the second one in the bathroom connected to the same connection) works fine. Unfortunately, all the pipes that connect to the battery are built under the bathtub and...

What is the installation made of? If welded, it is possible that badly welded and the lumen of the tube is significantly reduced. Mixer faucet? The crap could have accumulated in him.

Do you have a strainer? Maybe clogged up?

zimny8 · Answer

Swap these taps to check if the other one works.

henry56 · Answer

and check the water flow after removing the battery, if the battery is powered by hoses, check the strainers in the hoses themselves because they often clog up there

jega · Answer

The strainer at the outlet will limit the outflow of both cold and hot so I understand it's ok. But maybe our strainer on the inlets and that's where it is clogged from the cold? There is no need to combine, unscrew the battery for a moment, check if the strainers are there and replace them if necessary (do not throw away!). If not, plug the hot water supply pipe and let the water flow to check what stream will flow from the cold supply pipe.

Welcome back. I have already replaced the battery once. She was old, so I saw a problem here. But the problem is still there. After removing the battery, the cold water from the outlet goes the same as with the battery - very poorly. I know the problem is somewhere under the bathtub. After removing the battery and inserting a thin armored cable there, I did not come across any resistance up to about 20 cm deep. The same on a warm channel. So I guess there's either a constriction or a knee or something. There was nothing else. Of course, by tapping the cable strongly and in both channels you can see delicate dirt. So there must be a stone. The question is whether you can try to remove it.

Rather, the hot water pipe will get stuck faster, weird. You can try it, drain the water from the pipe and pour warm hot vinegar from the faucet side and leave it for a few hours.

You do not have access to the bathtub? Maybe tap on the tiles near the siphon and it will turn out that one is removable? If there is no door. And you could blow into the cold pipe with the faucet in the sink open?

skarpy · Answer

Thank you for your help. I will do just that in the coming days. I don't know if it matters, but every time (with or without a battery) I turn on cold water it is a kind of recoil. As if the water was going to shoot out powerfully for a moment, but that's the end and it's still going slowly.

kkknc · Answer

So it's somewhere further away. Maybe, as I wrote, the valve and the strainer on it.

skarpy · Answer

As I wrote above - I cannot do without forging. Probably in the future I will have to do it when replacing the tiles, but for now it is impossible. I have nothing to blow into the hole.

jega · Answer

And don't you have separate shut-off valves for cold and hot water somewhere before? Because if they are, cut off the cold one, open the tap at the sink to the hot one and connect the outlets to the shower (cold - warm) with a hose. This way you rinse the cold water pipe with warm upstream. From poverty, you could even rinse it with some scale-dissolving solution in a similar way. It's just that as the tap at the sink is sensitive to dust, you can get into trouble with it, so it's better to disconnect the hose and if the shut-off valve has a strainer (and it should), unscrew the entire valve for this rinsing.

arelektroda · Answer

My friend @jega's proposal is very good, but it will be fully effective when you find a place on the cold water pipe where you can open it so that any dust pushed with warm water can flow out. Unscrewing the cold water pipe, of course, after closing the main valve.

jega · Answer

From the discussion, I understood that the water is led to the washbasin (where there is no problem) and then to the bathtub, where it does not want to flow even after removing the battery. If so, then the place to unscrew is the connection of the washbasin faucet.

Strumien swiadomosci swia · Answer

Perhaps on the elbow, perhaps on the valves under the plates.

arelektroda · Answer

Well, try to unscrew the sink faucet and give it warm, as I wrote, and you will see if something flows out or worse, there will be no flow.

retrofood · Answer

It won't do anything. If the plumber used fittings of different materials to connect the faucet to the pipes, electrochemical voltage has deposited sludge on the walls and the hole in them is clogged. Only disassembly and cleaning or replacement with new ones. I used to have it at the water meter. The installation was made in a time when everything was missing, so the galvanized steel was separated with brass and that was enough. After a few years it became stuck to the amen. You can not clean it with any wire, because when wet it is rock. Only unscrewing and drying will allow you to scrape the muck, but it's best to do the whole thing on new, homogeneous elements.

There is also another option. Flat picked up before sale and bent hose. It flies, it flies, no one will notice the low pressure before buying. What does it mean? Do you have a tee from which connections for two batteries come out? Do you have the entire tub rig rigidly pulled? Are you sure that the bathtub cannot be put out of the building? Sometimes it is done that the buildings are permanent, but the bathtub can be easily removed. Acid advice is quite dangerous. First of all, we don't know what the installation is for. Thus, pouring acid (10% vinegar will not do anything in such a blockage, here you would have to use e.g. salt), can destroy the installation.

Hello, I have the same problem with the pipes, and exactly with the cold, everything is checked and probably somewhere on the tee that separates the water flow is blocked on the sink and there is no pressure ... the rest of the house, everything is cool, someone has an idea how to fix it without breaking the bathroom, installation old type.

kkknc · Answer

The ideas given above. Nothing has changed.

all009 · Answer

everything has been checked, I only have to try to connect the water and let the hot one go against the current to the cold one, maybe something will go wrong, if that does not help, then you have to disassemble the bathroom, i.e. disassemble the bathtub to get to the pipes ..
