PVC drain pipe installation labor cost reference: by meter or by item is more reasonable

When decorating to the water pipe link, many people will be confused by the installation fee of PVC drain pipes - the master reported "25 yuan/meter by meter" and "800 yuan/set by item", which is more cost-effective? In fact, there is no absolute "right or wrong". The key is to figure out the logic and hidden costs of the two methods, and then choose the construction scene of your own home.

Let's talk about the most common "calculated by meter" first. This method is based on the actual length of the pipe laid. For example, 10 meters of pipe will be charged at a unit price of 10. The advantage is that it is "clearly priced", and the number of meters is clear at a glance. It is suitable for scenes where the pipe is simple and there are few accessories (such as a new straight pipe on the balcony). But pay attention to two pits: one is "whether the unit price includes accessories" - the "25 yuan/meter" quoted by some masters only counts the pipeline itself, and the elbows, tee and trap will cost extra (5-10 yuan each); the other is "whether the auxiliary works are extra" - the manual work of slotting, punching, and dismantling old pipes, many quotations calculated by meters are not included, and may cost 100-300 yuan later. For example, if you want to install a 15-meter drain pipe in your home, the basic fee is 375 yuan at 25 yuan/meter, plus 5 accessories of 30 yuan and the slotting fee of 200 yuan. The total cost will reach 605 yuan, which is much higher than originally thought.

Look at "itemized calculation" again (also called "set calculation"). It is to package the installation of drain pipes in an area into one item, such as 800 yuan for "the renovation of the whole drain pipe in the bathroom" and 300 yuan for "the drain pipe in the kitchen sink". The advantage of this method is "worry-free" - no matter how long the pipe is or how many accessories are, it is all-inclusive at one price, which is suitable for complex construction scenarios (such as dismantling old pipes in the bathroom of the old house + rearranging pipes + repairing walls). But be wary of "unclear boundaries of items" - for example, the master said "calculate by item", but did not say whether to dismantle the old pipes or not, and did not say whether to add money to repair the wall. Later, the fee may be increased on the grounds of "you didn't ask For example, for the renovation of the bathroom in your old house, the master reported 800 yuan as an item. As a result, during the construction, he said "200 yuan for dismantling the old pipe" and 150 yuan for replenishing the wall, "and the total cost rose to 1,150 yuan.

So how to choose? In fact, the core is to "match the construction complexity": if it is a simple project (such as adding a balcony straight pipe, replacing a damaged kitchen drain pipe), the pipe is straight and there are few accessories, and it is more transparent to choose "by the meter" - as long as you ask in advance "whether the unit price includes accessories or not, and whether auxiliary projects are extra", the total price can be accurately controlled; if it is a complex project (such as the renovation of the whole house drain pipe, the old house is multi-regional pipe distribution), involving dismantling, grooving, and multiple elbows, choosing "by the item" is more worry-free - but be sure to write clearly before construction "all the work included in the item" (such as dismantling the old pipe, slotting, wall repair, accessories, accessories, accessories) to avoid adding money later.

Finally, I give two practical suggestions: no matter which way you choose, the first is to "list the details" - write clearly "price per meter, unit price of accessories, auxiliary engineering cost" by meter; write clearly "all construction content included" by item. The second is to "compare the total price" - for example, the renovation of your bathroom may cost 1,000 yuan by meter (25 yuan for 15 meters + 50 yuan for accessories + 200 yuan for slots + 200 yuan for dismantling). If the master quotes 900 yuan by item and includes all the content, it is more cost-effective to calculate by item.

After all, there is no "who is more reasonable" for the two billing methods, only "who is more suitable". The key is to turn "vague verbal promises" into "clear written agreements" to avoid "cost surprises" in renovations.
