Metal pipe fittings

[guru]

Does anyone know what thread the metal pipe fittings, often used outside to connect from water meters to tanks are? Are they BSP? If so, what size is commonly used?

[philyesil]

Hi Guru, the galvanised steel piping used generally for plumbing is threaded BSP. The smaller pipe commonlyused is 1/2" BSP.The nect sizeup is 3/4"BSP, then 1", 1 1/4 BSP, etc. These threads are usually sold in a set f dies at most builders merchants. Hope this helps. Plastic pipes are becoming more popular but they are usually welded together.

My husband says:

If you can’t get at the pipes easily, put some grease on it and take a print of the thread with a piece of paper and then measure how many tpi (threads per inch), measure the dia of the pipe (he can't remeber if it should be the internal or external measurement)

[dippersgirl]

there are tables to to inform you more, Zeus prodused them

Hi thanks for the replies. We get a lot of grit and stuff in our taps so was thinking of fitting a sediment filter between the mains supply and the tank. Do you think it would fit? Comes with either 1 or 1 and half inch BSP threaded connectors

A few thoughts. Normally tanks have a gap at the bottom, 2-3 inches where most sediment and scale will collect. Sometimes with metal tanks they are drained from the bottom so no sediment.

If you have a lot of sediment it could be being re-cycled into your house water, it is also a great breeding ground for legionella so it is wise to clear out.

I posted this on a different thread:-

I was having trouble with my combi boiler. Plumber said he needed to get a recirculating machine to descale the heat exchanger but got it working a little better. I put 1 kg of pool acid granules in my tank which is 5 tonnes and used it normally till the tank was empty took about 3 weeks. I got piles of limescale out of the system and now the water is as hot as I have ever known and the boiler is on its lowest setting. We used the water as normal for showers etc, my skin may have been slightly drier than normal. We used fresh mains for all consumable water though. There has also been a marked difference in the amount of scale in the tap nozzles too. Worth a thought.""

Since doing this I have had no scale in the tap filters the last two weeks.

Message me if I can help further

Hi Jonnie, thanks for the reply.

We are in Esentepe and have a mains supply from the village to our underground 2 ton cold tank. We have standard hot tank on the roof. The cold tank has a layer of silt on the bottom, but as you say the pick up pipe that feeds the pump is off the bottom. However, we still regularly get the tap filters caked with grit and gunk. We do get the tank cleaned out but still the silt re-appears eventually, so it must be in the mains water supply.

I'm considering installing a water softener outside between the mains supply and the cold tank to combat the hard water and scale. Installing it between mains and cold tank would mean that ALL the water to our property including through the pump, pipes, taps, tanks etc will be softened water and would stop all scaling. However, b4 I do that I have to install a sediment filter to filter out this b4 it goes through the softener.

I'm still checking out whether a softener will fit and work ok in Cyprus, but even If I decide not to, the sediment filter will still ensure our tank and tap filters stay clean.

Does ayone know if water softeners are available in TRNC?

[emineden]

water softeners are available here, there is a shop by the lights at the Bellapais turning that sells them.

[guru]

Hi eminden, do you know the name of the shop at all?

I dare say they'll be double the price but at least it means I could buy the salt here.

I think I'll do a seperate post to see if anyone has one fitted.

[Jonnie]

I think you will find the shop to be Siba, they do pool equipment and chemicals too.

What you are finding in the tap filters will be build up braking off the pipework largely, a bit like the scale in your kettle.

Hi,

I agree jonnie, but looking in my tank regular sediment appears on the bottom (2 ton underground plastic tank) so it would seem to me that it's also in the main supply coming from Esentepe beledeysi.

I had the tank cleaned last year and plan to get it cleaned regularly but that's why I'm thinking a whole house filter might be a good move. I've also been advised that a water softener (if I decide to go that far) needs a clean supply so I think a sedimemnt filter will be my first move.

Only thing I need to do is decide where in the line between meter and tank to fit it. It's galv' steel pipe from the meter, but somewhere underground it becomes black plastic pipe.

It connects to a float valve just inside the tank under the removable lid. At the top of picture it's the black pipe on the RHS with 90 degree elbow entering the tank.

Does anyone know what size this black plastic pipe might be, and also what sort of fittings are avalable for this pipe, compression, push fit, solvent weld etc???

Regarding the grit problem in the taps etc, this can easily be overcome. You need to fit a small brass filter unit on the supply to the ball valve. I got my in UK and it is simply a brass chamber with a wire fiter about the same size of the pipe. The filter can be removed for cleaning as it has a simple nut screw end and since installed, no problems with grit as it all falls to the bottom chamber of the filter as the water is supplied.

Hi

Where did you get the filter from? Do you have a link to a website at all?

Also, the black plastic pipe to the float valve, (picture above) I presume this is MDPE pipe - any idea what size it might be (20mm? 25mm?)

I was thinking of one of these - whole house sediment filters http://www.pozzani.co.uk/water-treatment-216/index.html,

Thanks harita, I've corrected it now

[Jonnie]

You can get the brass fittings at the Yapi markets here. I would say the black pipe looks like 20mm to me but it is impossible to say for sure.

With regards to the filter that I mentioned, it is called an inline Y filter. These can be purchased through Toolstation outlets or their online store, catalogue number 52821 (15mm) & 16650 (22mm). Both of these come with compression nuts that can be attached to either copper or plastic pipe. The one that I have fitted is slightly different to that shown in the Toolstation catalogue as it is a half inch female iron but the items detailed do exactly the same job and should be fine with standard pipe dimensions here in the UK. Hope that helps.

Thanks for that. Two questions. 1) Does it matter which end the blanking plug faces i.e. downwards, upwards, sidewards 2) do you have this on the mains supply TO your tank or on the outlet FROM your tank to your pump?

[pc4854]

Not sure what is meant by the "Blanking Plug" if that is the removable filter then it should be at the bottom of the pipe so that the grit falls into the chamber. I empty my chamber once a year. My unit is fitted on the main supply to the underground water depot, this was found to be best as the grit was fouling the ball valve which allowed the mains water into the depot and on one occasion caused an overflow into the pump room, now not a problem.

Hiya, yes I meant the removable filter, thanks again will give it a try.
