Hi, I have fitted a water pressure restrictor but am puzzled that when I turn the cold tap on and then off the pressure stabilises at 3.5 bar as expected. However, when I do the same with the hot tap it reads almost 6 bar! I know that hot water expanding will cause the pressure to rise but I...

Hi, I have a problem where an existing wooden gutter has been joined (not very well!!)to a neighbour's plastic rainwater gutter and is leaking. My initial thoughts were to fibreglass over the joint, but I don't think the plastic gutter would adhere very well to the glass. Is there a gutter...

Hi, Anyone got any ideas on this one? I’ve got a combi boiler and a water meter. Fitted a pressure reducer set to 3 bar but got pressure increase after demanding hot water so fitted a mini expansion vessel (0.16l) to the cold mains near boiler. I got water hammer when the hot tap in either...

Hi, Just starting to install the above into vertical mains pipe flowing upwards. The instructions say if mounting vertically it should be installed with the spring bonnet adjuster uppermost, however if I put it in like that the flow will be opposite to that marked on the valve. Can anybody...

Hi, I recently fitted a mains water pressure reducer and set the pressure to 3 bar. When the cold taps were turned on and then off, the pressure reading returned to 3 bar, but with the hot tap it was 4 bar. About 3 months after fitting the pressure instantaneously rises so that the guage spins...

Just a quickie, I have a Baxi 105e weeping near the spindle at the front of the DWH diverter. Does the o ring fit internally on the spindle (meaning the front and rear parts of the diverter assembly have to be dismantled) or can it be replaced by just removing the gland nut on the front and...

Hi, I own a property near to a site where a builder is starting work on a new build. He has intimated that he/his utility providers will need to dig up my drive/garden to lay services. Is he legally entitled to do this?

Hi, We have a cottage that sits very close to a lane (see pic) and a builder is starting to build a new property next door but one to us. Today he cut down a shrub that is tied to our wall and told me it will need to be removed completely when he connects the services to the new property. I...

Hi, I have a problem with a system that collects water in a well for garden use. It has a Leader Divertron 1000 submersible pump that is activated by either of 2 garden taps, and was tripping the RCCB in the house. I found a junction box at the top of the well was wet inside and sorted it with...

Hi, Not sure if anyone will be able to help me with this. I've been trying to make a junction box connection in the top of an underground garden rainwater storage tank. The SWA feed cable has had the correct gland fitted and screwed into a 20mm thread in the box. The flexible round cable from...

Hi, I have a problem with no hot water from the 105HE boiler. The pin that activates the microswitch on the front of the pressure differential valve isn't moving. The diaphragm was replaced only a month ago. Is this the sole cause of the pin not moving or could it be another diaphragm within the...

Hi, About 5 weeks ago I had a problem with the boiler having too high pressure, so pressurised the expansion tank and all hunky dory. Today the pressure rose again, so I repeated. I'm thinking the expansion diaphragm is porous??(boiler about 15 years old) and pressure is now steady. My thinking...

Hi, I have a 105E that has leaked from behind the pressure diff. valve. The boiler pressure is zero. Before I leap to the conclusion tht the diaphragm on the diverter valve assembly is broken, would this cause the pressure to drop to zero? Many thanks

Hi, I have a Potterton central heating boiler that has failed the landlord gas safety check. I have been told the seal has failed leading to the chance of dangerous gasses affecting the property, and it has been suggested that the boiler is replaced (it's about 15 years old). In no way do I...

I have a 16mm O/D water pipe which I have managed to dent with a spade. Compression joints would be easiest for me - can they be used underground? Also, normal compession joints are 15mm standard. Any advice? (I have used Philmac connectors on alkathene pipes before but not sure if suitable for...

Hi, I wonder if you could please advise me on the following: The heating in our house has a Centaurplus C11 control fitted in a bedroom and a Digital Programmable Thermostat Model 099A fitted at the top of the stairs. The 099A control is difficult to use at the best of times, the display is very...

Hi, My son has recently moved into a house with a mains water supply entering through a cellar. There is misalignment in the copper water pipe where it enters a service valve and it is slightly leaking. My first thought was to cut out the mis-aligned section and replace with a flexible...

I have a Baxi 105e which is only used for DHW (the CH system is disconnected). It delivers hot water but when the hot water tap is shut off and then opened again, the "triangle/pyramid symbol" fault neon flashes. I've tried to follow the fault finding steps in the manual, the DHW diverter...

Hi, I have been asked to install an armoured cable to connect a greenhouse to the existing 16A supply in an outhouse. I will lay the cable and wire up splashproof sockets and light fittings for their electrician to check and connect to supply. I intend using 2 core cable with the steel armour as...

Hi, A neighbour of mine is currently extending a property and using the existing garage plus 2 new spaces created on the plot to achieve the 3 spaces required for permission for the 4 bed property. As he also owns the adjacent land to the plot and now intends to re-draw the property boundaries...
