Just fitted a large and heavy stone shower tray onto a mortar bed. I forgot to run silicon sealant around the edges, before tanking with liquid latex and adhesive repair tape from Aquaseal. The tape overlaps onto the shower tray, making a waterproof seal all around it. Do I now need to cut the...

I have just replaced two ceiling chandeliers with LED ones. Each has 24 bulbs @ 4W each. Both are driven from two 2-gang 3-way dimmer switches, which also drive some wall sconces (6 bulbs @4W each). So, in total each 3-way dimmer switch is driving 54 LED bulbs (all 240v), totalling around...

Rads getting hot when just CH is on. Always been this way. Think I may be getting reverse flow. S config. Trad non-combi boiler. Header tank. Boiler is a Stelrad Mexico. Pipes run boiler to pump to t piece that splits to hw 2-way zone valve to hw tank one way; and ch 2-way zone valve...

I have a problem where the wall-lights in just two downstairs rooms have burnt and melted. I have no problems in other rooms. Living room and hallway - all the light fittings have burnt. They are BTC Hector wall-lights, which take 40w golfballs, and have a porcelain shade that is held in...

Why oh why does it take a posting to DIYnot to get a sensible answer to these questions: the building firm are currently playing dumb, perhaps because this could be expensive to fix. Anyway, thank you for your most valuable help. I've retrieved the instructions for the pump: "For the pump...

The benefit of hindsight... Well, you're onto something. I tried the trick of lower the head gently, and it starts working when I drop it half way to the shower tray. Every time. Interestingly, this is the exact height of the shower pump behind the tiling. Weird thing: we did test the...

Yes, same setup. The building firm sent round some new plumbers, who spent a day "fixing" the plumbing as follows: Fitting flange into the bottom of the HWC Replacing air valve for "correct" kind Fixing some of the speedfit joints that were poorly done However, speedfit pipe still used...

The shower has only just been installed. The pump is a Stuart Turner 3 bar twin pump. Thanks Potemkin

I have a power-shower that works very well. Except, when I switch on the water, nothing comes out of the shower and the pump doesn't make a sound. I then have to lift the shower head off its hook and shakeit around for a moment; whereupon suddenly the pump kicks in and the shower works like a...

...he agreed that the pump was too far from the HWC, also that the piping ran up throught the loft above the HW vent. His solution: leave the pump where it is, but drill into the bottom of the HWC and fit an essex flange to the existing pipework. I'm not convinced. Won't this still meant...

I really appreciate the excellent advice - thank you. In the meantime, I will consider whether to get in the firm or try to fit the surrey myself. I'll post some pics of the rest of the run, but basically, the plastic pipe goes about 35 feet to the pump (over hill and down dale), which rests...

I am attempting to post the pictures you requested. The plastic pipe is the one going to the shower. In fact, it goes up into the roof, runs quite high up, reaching an air outlet valve at its highest point, then dips down to the shower pump. I tried opening each of the speedfit pipe...

I lived with a fan that doesn't run on after switching off the lights. It's a minor annoyance, and rewiring would have required some major surgery to a room that I've just completed...

I do have a Surrey Flange (or something similar at least) on the top of the HWC. Interestingly, the air lock has returned today. No HW from the shower, and the pump stops when the thermostat is turned to Hot. I'll go into the loft and wiggle the valve to release trapped air. Could there...

I really want to thank you for this wonderful site, and your very kind assistance. Your advice was excellent Richard

Excellent advice, and really speedy too! I really want to thank you for this wonderful site, and your very kind assistance. Richard

Thank you! I tried venting whilst the shower is on. Lots of air coming out the vent. Hot water coming out the shower. Pump on. Lots of gurgling, which tells me air is moving up to the vent. Should I leave the vent open (do you think it has a one-way valve), or will it suck air back into...

I have a new shower and pump, installed by a building firm. I tried it for the first time, and discovered that the shower gives cold water but no hot. I suspect this is down to an air lock in the hot water pipe leading to the pump/shower. At its highest point, this pipe has a valve, tall with...

A dumb question I suppose, but I would really welcome any advice. I am fitting a new shower hose to a new shower water outlet in a new bathroom. The hose terminates in a male screw fitting of half an inch diameter. The water outlet is a female screw fitting to match. Fine so far. When I...

A building firm did the first fix for my bathroom. SInce then, we've had the room tiled and painted. One of the final acts was to wire up the extractor fan, one of the standard run-one types. Here I've hit a problem. The cable installed by the building firm is only two core and earth...
